* Four out of six members of the original lineup of Swedish {{Horrible History|Metal}} PowerMetal band Music/{{Sabaton}} left to form the very similar[[note]]still mostly military history themed music, but MetalScream vocals instead of a basso growl[[/note]] Music/{{Civil War|Band}} after recording ''Carolus Rex'' in 2012, citing fatigue with Sabaton's touring schedule and a desire to have more of a role in songwriting. Sabaton frontman Joakim Brodén says they're still friends but admits things were tense at the time.
* In 1968, Creator/{{Motown}}'s star production team, Brian & Eddie Holland and Lamont Dozier, got into a financial dispute with Berry Gordy and when he didn't budge, left to form their own record label, Invictus/Hot Wax.

* Laharl in ''VideoGame/Disgaea2CursedMemories'': "I don't even wanna be a part of this stupid world. I wouldn't stay if you begged me! I’ll go find a better world, with heaps of food! And cookies!"
* In ''VideoGame/{{Terranigma}}'', Marily from Loire works at Mme. Papilo's expensive boutique at low pay, but after Loire expands, you can help her start her own boutique that sells affordable clothing to the masses.
* ''VideoGame/Fallout3'':
** If you manage to depose President Dave, he'll leave with plans to start a new republic. Presumably one that's better and without people who get more votes than him. It does not go well. And if you provoke him while he's in a slump, he'll attack you.
** [[spoiler:The Enclave]] is also a form of this. After their main headquarters in the Pacific went boom, their chief intelligence in D.C. figured "fuck it" and reformed the remnants as his own democracy, rather than a fake democracy of royal presidents. Not that he's any better - [[spoiler:it's a low blow to call an AI an inhuman monster and someone who can't vote, but it logic bombs him to death.]]
* In ''VideoGame/FalloutNewVegas'', one of the options for the White Glove Society sidequest is to expose Mortimer as a cannibal. When he realizes that he won't be able to turn the rest of the society (who are reformed cannibals) back to the old ways, he declares that he'll build an even better society before running off. You can also build your own empire after disregarding both Legion and NCR and killing or subduing Mr. House. And since it's Vegas, it ''will'' have TabletopGame/{{blackjack}} and hookers!
* The Saikyo-ryu (lit. "Strongest Style") dojo started by ''Franchise/StreetFighter''[='=]s Dan Hibiki is his answer to being booted out of Gouken's Ansatsuken dojo for being too {{Revenge}}-obsessed with Sagat in his training.

* ''VideoGame/MarioPartyIslandTour'': Bowser, unhappy for not being invited to Party Islands whereas Mario and his friends were, decides to place an ominous tower in front of them called Bowser's Tower, hoping to draw more attention and also creating evil bubble clones from a machine.
* After being kicked out of nearly every guild, this is what motivates Karol to start one with Yuri in ''VideoGame/TalesOfVesperia.''

* In their A rank support in ''VideoGame/FireEmblemThreeHouses'', Petra invites Ashe to come with her to her home nation Brigid. While Ashe admits he'd like to visit, he still wants to focus on his GoalInLife to become a knight and thus contend with that duty. Petra, as the future queen of Brigid, offers to establish an order of knights in Brigid for Ashe to be a part of. [[spoiler:If the two are paired together, the epilogue will say that Petra ''did'' found an order of knights with Ashe's guidance, naming them the Blue Sun Order and using them to declare independence from Fódlan.]]
* In ''Fashion Forward'' Risha decides to start her own clothing boutique because none of the ones she's visited in Hollywood have non-petite sizes.

* In ''Webcomic/KevinAndKell'', after R.L. ousts Kell as Herd Thinners C.E.O. and kills all of the changes Kell made to the company, Kell decides to open a competing company, with encouragement and backing from [[spoiler: The Rabbit Council, who see Kell's potential company as a way to eliminate their own competition - i.e. other prey species.]]
* In ''Webcomic/DanAndMabsFurryAdventures'', the three times we know about this happening two ended disastrously. Probably has something to do with the instigators of the first two being [[BlueAndOrangeMorality Creatures]].
** First, the Cubi Cyra decided to take over a city called Hishaan from the dragon M'Chek, but after she succeeded in killing him an unexpected energy surge [[http://www.missmab.com/Comics/Vol_1217.php destroyed the city]] and in the process kickstarted the genocidal Dragon/Cubi War that resulted in the deaths of almost all of Cyra's children save one and the complete destruction of many other clans.
** Second, the Demon Aliph Soulstealer/Dark Pegasus was snubbed for a position of leadership in his family's city of Zinvth, so he [[http://dmfa.katbox.net/comic/1552-at-least-he-is-ambitious/ tried to make his own]] and wound up accidentally creating the Undead race in the process when he [[http://dmfa.katbox.net/comic/1560-typos-the-oldest-mistake-in-the-book/ screwed up a spell]] and made his would-be puppets self-aware.
** The third was the direct result of the second, when the newly sentient Undead decided to make their own nation and founded Trik'na Island, where they can live in peace without fear of being killed on sight. It's actually very successful economically since its residents neither need to eat or sleep, but the living world is reluctant to deal with them.
* ''WebComic/TheOrderOfTheStick'' prequel volume that [[StartOfDarkness shows the backstory of Xykon and Redcloak and how they came to be villains]] shows us that Xykon, then a young sorcerer, once did this. As an apprentice to [[NamesToRunAwayFromReallyFast The Unholy Master]], Xykon was under consideration to be promoted to the NumberTwo position... but was [[PassedOverPromotion passed over]] in favor of ''both'' his FriendlyRival (and sometimes lover) Yydranna and [[TheCameo Keith Baker]]. (A real life FriendlyRival to the author of OOTS.) Furious at having Baker chosen over him, Xykon decided it was time to quit being an apprentice and go into business as a villain for himself.
* ''Webcomic/GuildedAge'': The effectiveness of the Gastonian Peacemakers was not lost on Harky, especially after the miserable defeat in B'ial Vezk, so in response he put forth a call to arms for a team of champions that would serve the World's Rebellion, one member from each race. It worked. Extremely well.
* PlayedForLaughs in ''Webcomic/EightBitTheater'' where not one, not two, but ''three'' groups of heroes ([[NominalHero for a given value of the term anyway]]) simultaneously dissolve their groups and form new ones amongst each other. Including the protagonists. And their, supposedly, mortal enemies. Even weirder, for three groups that initially consisted of four members each (for a total of twelve people) they somehow ended up with five teams. Then six teams. The entire matter was dropped when no one could remember whom their new allies were.

* The above quote and TropeNamer is from the ''WesternAnimation/{{Futurama}}'' episode "The Series Has Landed" after Bender is kicked out of Lunar Park, and later when Fry and Leela keep Bender out of the Apollo 11 lunar lander. The line has gone on to become a [[MemeticMutation popular meme]].

* An episode of ''WesternAnimation/{{Arthur}}'' revolves around the kids creating their own "[[Film/JamesBond James Hound]]" movie, since they're not old enough to see the actual PG-13 movie themselves. They eventually discover that all the outtakes are actually [[SoBadItsGood better than what they planned]].
** An earlier one involved Muffy getting fed up with Arthur's shabby clubhouse and leaving to start her own club, and Buster and Francine deciding to join her. Gradually, ''everyone'' abandons not only Arthur's never-been-official-anyway club, but each other's as well, until everyone is a one-person "club" of their own. Eventually they all realize how stupid it all turned out, and get back together.
** A later one involves Francine and a group of friends starting a band called U Stink, but Francine quits and starts her own band called We Stink with Arthur, Buster and George. Arthur and Buster end up getting mad at her and quitting, claiming they will form their own band and call it She Stinks. George doesn't mind staying, but Francine gives up.
* Similarly, in ''WesternAnimation/RocketPower'', the kids try to make their own movie and find it to be much harder than they were expecting.
** The kids, in response to a movie that they agreed was terrible, end up filming a movie. The episode ends with a younger group of kids deciding that the movie that was filmed by the original group [[BookEnds was also terrible, and set off to create their own film]].
* Creator/HannaBarbera's ''WesternAnimation/TheLittleRascals'':
** In "Beauty Queen for a Day", when Alfalfa won't let Darla into the He-Man Woman-Haters' Club, Darla threatens to organize a She-Woman Man-Haters' Club: "And there will be no '''''boys''''' allowed!"
** In "Big Top Rascals", the Rascals put on their own circus after being denied admission to a real circus. Darla had told the circus owner that she and the boys were tending the animals because they had no money for tickets.
* The male unicorn decides to build [[TheGreatFlood his own ark]] after missing Noah's on ''WesternAnimation/RobotChicken''. [[http://www.adultswim.com/video/?episodeID=8687905da0a1166b82131930b0001010]]
* In the ''WesternAnimation/CareBearsAdventuresInCareALot'' episode, "Whose Friend is Who?" a bit of a club war gets started because Cheer, Harmony, and Love-a-Lot reject Funshine and Oopsy's help in making a "project" with their human friend [=McKenna=]. So, with Grumpy, they make their own "project" and a subsequent club to go with it. The girls retaliate by forming their own club, and a montage of the two clubs one-upping each other in their projects ensues, with [=McKenna=] stuck in the middle, not wanting to pick a side. She eventually gets the two clubs to see how silly they're being by making a club with [[RobotBuddy Wingnut]], and calls them out when they band together to exclude her club.
* In ''WesternAnimation/FamilyGuy'', Peter is so jealous of Joe's home movie theater that he decides to build an addition onto his house to create an even bigger and better theater than Joe's. Of course, this plot is quickly forgotten once Peter digs up an Indian skull and the real plot of the episode starts.
* A ''WesternAnimation/LooneyTunes'' cartoon started with Daffy Duck as a janitor of an inn that belonged to Porky Pig. Daffy was feeling unappreciated and, when Porky tried to show his appreciation by giving him a new broom, Daffy decided to start his own inn. [[FailureIsTheOnlyOption Daffy's dishonest attempts to run his former employer out of business backfired.]] His last plan consisted of blowing up Porky's inn. [[spoiler: Daffy DID blow up Porky's inn, but accidentally revealed the presence of oil under it, allowing Porky to build an even better inn. To show Daffy he doesn't keep hard feelings, Porky hired him to work at the new inn... [[WhereItAllBegan as a janitor]].]]
* One episode of the ''ComicStrip/{{Dennis the Menace|US}}'' animated series portrayed Dennis and Margareth as business partners in a lemonade stand. Unsatisfied with her share of the profits, she started her own lemonade stand to compete against her now former business partner.

Soon everyone leaves Edward's club after finding it too boring (it's all about talking about how much they hate Lazlo, which only Edward does) and head over to Lazlo's.

* A StoryArc of ''Series/TheOfficeUS'' focused on Michael Scott quitting Dunder-Mifflin to start the Michael Scott Paper Company. By the second episode of the arc he was at it again: "I should leave them and start my own paper company. That'll show them." Either he's in some sort of feedback loop or it's a writer's [[LampshadeHanging lampshade]].

* ''Series/{{Smallville}}'' episode "Pandora" has [[spoiler: Future]] Chloe take Lois to Watchtower. She responds with this line:

* A common trope for the gang in ''Series/ItsAlwaysSunnyInPhiladelphia''. Among many examples, they started their own band after seeing Dee's ambiguously retarded boyfriend being a hit rapper. They also wanted to launch their own gasoline preservation to make money for the bar. [[CloudCuckoolander Charlie]] at some point, writes and directs his own musical. The list just goes on and on, including a desire to start their own police force, clothing line, Dennis running for comptroller, [[MisaimedMarketing an all-age drinking bar]], their own radio station, and so forth... it usually all descends into WeAreStrugglingTogether category.
* On ''Series/HowIMetYourMother'' Barney and Ted always wanted to start their own bar called Puzzles. On New Year's Eve 2011 they are outraged by the high cover charge at their usual bar and jokingly suggest that they should just start their own bar in Ted's apartment.

And so on...
* An episode of ''Series/{{Frasier}}'' had this happen with Frasier and Niles's wine club. Frasier is tapped to become the head, or "Corkmaster," of the group, only for Niles to run against him in an election. This naturally leads to fighting and arguing, at which point Martin comes down and reminds his sons that they used to do the same thing when playing as children.

* ''Mosley''. After a speech denouncing the British government's inept response to the Great Depression, several other politicians offer an alliance with Oswald Mosley.

* After being fired from Music/{{Metallica}} prior to the release of ''Kill 'Em All'', Dave Mustaine formed Music/{{Megadeth}}.

* HeavyMetal band Music/{{Motorhead}} was formed when Lemmy Kilmister was given the boot from [[SpaceRock space rockers]] Music/{{Hawkwind}}.

* Original Music/{{Weezer}} bassist Matt Sharp started the Rentals out of a desire to do his own take on early New Wave rock, and made it his full time job after butting heads with Rivers Cuomo.

* Ryuusuke and Eiji of ''[[Manga/{{BECK}} BECK: Mongolian Chop Squad]]'' initially play in the same band, Serial Mama, until personal differences and a missed opportunity with a record producer drive them apart.

* In ''LightNovel/LoveChunibyoAndOtherDelusions'', Rikka forms her own school club, the "Far Eastern Magical Nap Association", which is more or less a legalized excuse to let her delusions run amuck with Yuuta, Kumin and Sanae tagging along, willing or not. Nanase-sensei approves the club as a social circle, only because she noticed Rikka's determination to see her dream come to life despite lacking the prerequisite five members. Then it becomes a full-fledged club once Shinka actually applies, [[spoiler:hinting to her past life as another deluded teen herself]].
* ''Manga/OnePiece'':

* Hoshi-no-Tsuji High and Middle School in ''Manga/MagicOfStella'' institutionalizes this trope, as it doesn't require a faculty advisor to start a JapaneseSchoolClub; a few student members and the appropriate paperwork already handles it. The series is about a club that make ''doujin games'', which would be unthinkable everywhere else.
* ''Anime/MobileSuitGundamIronBloodedOrphans'': The main characters are ChildSoldiers who serve as [[WeHaveReserves expendable cannon fodder]] for a {{PMC}} who use "Run away while using the brats as human shields" as Plan A...and Plans B, C, D, etc. Understandably, they have issues with this, so they decide to start their own...[[TurnedAgainstTheirMasters by killing off their bosses]] and taking over their facilities, changing the name from CGS to Tekkadan.
* This is implied of the Outdoor Activities Club in ''Manga/LaidBackCamp''. The Outdoor Activities Club was born of Chiaki and Aoi's desire to experience the outdoors at a much more relaxed pace than the athletically-focused Hiking Club.
* Kanna ''Manga/MissKobayashisDragonMaid'' has very little interest in joining any of the established dragon factions [[DadsOffFightingInTheWar due to the war being responsible for her parents' neglect]]. Instead, she started the "Kanna Faction".
* Like the ''Manga/MagicOfStella'' example above, Sakuragaoka High School in ''Manga/TheDemonGirlNextDoor'' has a rather hands-off attitude on the establishment of clubs, as long as the club's objective can be fulfilled in the entire time the applicant is in school. As a result, the school has clubs for black magic, polishing human specimens, drafting anti-zombie manuals, or just playing with cats, while Mikan's proposal of growing tangerines (her namesake) is rejected, since it takes five years for the tree to start bearing fruit.
* After certain events reveal the [[CorruptCorporateExecutive corruption]] and incompetence of parts of the Hero Association from ''Webcomic/OnePunchMan'', [[spoiler:various members, both heroes and staff leave to start the Neo-Hero Organization. Their reasons, however, are very different; [[AmbitionIsEvil McCoy]] seems to be doing it for the power and wealth, [[ChildProdigy Child Emperor]] actually wants to make improvements to the hero system, and other heroes like [[HotBlooded Metal Bat]] were simply offered better pay and benefits]].
* In the backstory of ''Manga/KarateShoukoushiKohinataMinoru'', Kaburagi Ryu karate started when their founder, Kaburagi Juzou, had to leave the already established Koudan Kaikan under undisclosed circumstances (Tachibana, who followed Kaburagi out of Koudan Kaikan, once claimed he was forced out by his former pupil Izumi when he became the Koudan Kaikan president, though Izumi denied the charge and stated Kaburagi should have become president in his place and left on his own).

* In Creator/GregRucka's 2011 run, Comicbook/ThePunisher takes on The Exchange, a bunch of former members of other various criminal organizations in the Marvel universe who decided to start their own organization.
* This trope seems to be [[ComicBook/IronMan Tony Stark's]] standard reaction whenever he loses control of Stark International.

* Since ''WesternAnimation/SpiderMan1967'' is well known as a [[MemeticMutation meme generator]], one particularly oft-used meme is one where Spider-Man declares that he'll form his own [[Franchise/TheAvengers Avengers]] team. With [[Franchise/TeenageMutantNinjaTurtles Ninja]] [[http://weknowmemes.com/wp-content/uploads/2012/09/spiderman-is-going-to-start-his-own-avengers.jpg Turtles]].

* In ''[[https://www.fanfiction.net/s/11707688/1/What-Are-You-Doing-Youth What Are You Doing? (Youth!)]]'', the citizens of Konoha pack up and leave (literally, they take the entire village) in response to learning that the Council has forbidden Naruto from becoming Hokage. It isn't until later that Sakura notes that with the stuff they've taken, they can form their own village and make Naruto a Kage.

* [[https://www.fanfiction.net/s/12714427/4/Up-Your-s-Dumbles In this chapter]] of ''Literature/HarryPotter'' fanfic "Up Your's Dumbles", Fudge and Umbridge are informed that the Daily Prophet's new major stockholder prohibited them from publishing lies and Umbridge starts thinking it's time the Ministry starts their own newspaper. She hopes the Malfoys will support the idea.
* A major turning point in ''Fanfic/TheNewAdventuresOfInvaderZim'' comes in Episode 17, when [[spoiler: the Tallest tell Zim the truth of his mission and abandon him on Earth. [[EvilMentor Norlock]] then channels Zim's rage over this into going rogue, with plans of creating an empire of his own and using it to take revenge]].
* ''Fanfic/PokemonResetBloodlines'' has this as the backstory for Teams Aqua and Magma. Archie and Maxie used to work for another organization known as Team Zenith, but ended up leaving due to a lot of disagreement and infighting amongs Zenith's members, and founded their own teams in their bid to change the world in their own way.
* ''Fanfic/LadyBugOut'' is kicked off when Marinette becomes frustrated enough with how Alya has been running her Ladyblog that she decides that Ladybug should start her ''own'' blog -- one where she can help straighten out some facts while working to better support and protect Paris.
* In ''[[https://www.fanfiction.net/s/1416637/1/Harry-s-Last-Stand-Against-Voldemort Harry's Last Stand Against Voldemort]]'' Dumbledore refuses to let Harry join the Order of the Phoenix so he decides to start his own order.
* In ''Fanfic/LegacySekiroKimetsuNoYaiba'', Kiyoshi decides that as a shinobi, the Breath of Thunder doesn't suit him, instead drawing upon its teachings to create a new Breath style, the Breath of Silence.
* A benevolent example in the PeggySue SeriesFic ''Fanfic/StartAgain'', where the Phantom Thieves are sent back to the past at different points in time and believe they are the only ones that remember. This leads them to form their own group of Phantom Thieves (respectfully Haru, a non-remembering Makoto, and [[spoiler:Akechi]]; Futaba and Yusuke; Ryuji and Ann) with new Persona users, [[spoiler:before coming together at the end of ''[[https://archiveofourown.org/works/16554959 Valor and Discretion]]'']].
* The plot of ''Fanfic/GleeReprise'' is kicked off by Rachel starting her own glee club out of the Kenmore Community Centre down the street from Carmel High after Beth is rejected from Vocal Adrenaline.

* ''Film/{{Paranoia2013}}'': Wyatt used to work for Goddard before he quit to start his own company.
* Hans Gruber from ''Film/DieHard''. The leader of the terrorist organization he used to belong in even called a TV station to say he no longer works for them. [[spoiler:Subverted. He didn't start a new terror cell, but a heist gang.]]
* ''WesternAnimation/{{Metegol}}'': [[spoiler:Unable to prevent El Grosso from destroying their town, the townspeople merely start another town elsewhere]].

* ''Film/OfGodsAndWarriors'' is about a Viking princess fighting to reclaim the throne that was denied to her by her uncle. The writer/director had a young daughter, had seen every Disney Princess film More Than Once, and felt moved to make his ''own'' princess film. His film is rated 18 [[note]] can only be legally bought or rented or seen in the cinema if 18 or over[[/note]] in the UK, so it will be a while before his daughter can watch it.

* We have this trope to thank for both ''Literature/TheLordOfTheRings'' and ''Literature/TheChroniclesOfNarnia''. Creator/JRRTolkien and Creator/CSLewis, good friends in college and both big fans of classic mythology, both became frustrated that no one was writing those kinds of stories anymore. Finally they both agreed that they should write those stories themselves.
* In ''Literature/ParadiseLost'', when all the demons are debating what to do next, Belial suggests that they could just apologize. Mammon, being the JerkAss that he is, shoots that down, and then suggests that they make their ''own'' heaven, although blackjack and hookers aren't mentioned (but you know it would have them).
* When ''Literature/TheBabysittersClub'' put [[ButtMonkey Mallory]] through a ridiculous series of training exercises in order to make her prove herself worthy of joining, she calls them out on their crap and starts her own club with her new best friend Jessi. It doesn't last, since the sitters eventually figure out that they were in fact acting like bitches and invite both girls to join the club.

* Happens a couple times in ''Literature/WarriorCats'':
** Some remnants of [=BloodClan=] decide to make their own Clan... in Ravenpaw and Barley's barn.
** Sol, [[spoiler:some time after parting ways with [=SkyClan=]]], attempts to form his own group in an abandoned Twoleg nest.
* In Jean Merrill's ''The Toothpaste Millionaire'' ''sixth-grader'' Rufus Mayflower responds to the high cost of store-bought toothpaste by starting his own toothpaste company with the help of his best friend.
* In Erwin Strauss's [[KeepCirculatingTheTapes out-of-print]] book ''How To Start Your Own Country'', he details ''how'' to start your own country.

* [[AllInTheManual Background material]] in the ''Literature/HarryPotter'' franchise reveals that the Ilvermorny School of Witchcraft and Wizardry in North America was founded by a witch who really wanted to attend Hogwarts but was prevented from doing it by her [[EvilUncle Evil Aunt]]. In an unintentional "screw you" to her supremacist aunt, who despised Hogwarts for allowing Muggle-born wizards and witches to attend, Ilvermorny was founded by the girl with the help of her Muggle (well, No-Maj since he's American) husband and their adopted sons. Thus, Ilvermorny became even more democratic than Hogwarts ever was, accepting wizards and witches regardless of their origin.

* After being fired from HeavyMithril ScienceFantasy band Music/{{Gloryhammer}} in 2021, vocalist Thomas Winkler (Angus McFife) has since started his own similar group, Music/AngusMcSix.

* In ''VideoGame/FalloutNewVegas'', one of the options for the White Glove Society sidequest is to expose Mortimer as a cannibal. When he realizes that he won't be able to turn the rest of the society (who are reformed cannibals) back to the old ways, he declares that he'll build an even better society before running off. You can also build your own empire after disregarding both Legion and NCR and killing or subduing Mr. House. And since it's Vegas, it ''will'' have blackjack and hookers!

* If you manage to depose President Dave in ''Videogame/{{Fallout 3}}'', he'll leave with plans to start a new republic. Presumably one that's better and without people who get more votes than him.

* Texas oil tycoon Clint Murchison Jr. wanted to buy the then-flagging Washington Redskins[[note]]later renamed the Commanders in 2022[[/note]] in 1958, but he backed out of the deal after Redskins owner George Preston Marshall changed the terms that were unfavorable to him. As a result, Murchison formed the Dallas Cowboys in 1960, and the most-well known rivalry in NFL history was born. What's more, Murchison purchased the rights to the Redskins' fight song, "Hail to the Redskins". Murchison gave the song back to Marshall, in exchange for Marshall's vote that would allow the Cowboys to be formed (at the time, a unanimous vote among NFL owners was required for a new team to be formed, and Marshall was the lone holdout, due to him wanting to maintain the Redskins' fanbase in the Southern US).
* This is the state of boxing with four "main" sanctioning bodies (five if you count the IBO): the WBO, IBF, WBC, and the WBA. This means that at any time there are (usually) four champions in any given weight class. Becoming "the" champ is damn near impossible because of a set of convoluted rules that pretty much disqualifies boxers from holding all the belts at the same time. This, compounded with all of them being notoriously corrupt and numerous other organizations springing up almost daily, effectively make belts worthless.[[note]]Only two boxers in the 2010s, Terence Crawford and Oleksandr Usyk, successfully unified all four belts. Crawford did it in the light-welterweight class in 2017, and Usyk in the cruiserweight class the following year. Less than two weeks after Crawford unified the light-welterweight belts, he gave up his IBF belt because he didn't plan to fight before that group's deadline to fight its top contender, and not long after that gave up his other belts and moved to the [[MoneyDearBoy more lucrative]] welterweight class. Usyk gave up his cruiserweight belts in 2019 to move to the even more lucrative heavyweight class.[[/note]]
* In March 1995, Tony George, head of the Indianapolis Motor Speedway (home of the Indy 500), announced the formation of the Indy Racing League (IRL; now known as INDYCAR), ostensibly to make open-wheel racing in America less Euro-centric and give more direct control of the sport to track owners. Oh, and the majority of the drivers at the Indianapolis 500 (25 out of 33) would now have to be from the IRL. The existing sanctioning body, CART, responded with a blanket boycott of all IRL races and scheduling the new US 500 to run at the same time as Indy. The split remained for thirteen years before the sport was reunified under the banner of IRL and its [[UsefulNotes/IndyCar IndyCar Series]]. [[HoistByHisOwnPetard Ironically]], racing fans, confused and frustrated by the split, turned in droves to stock car racing and NASCAR.
* The American Basketball Association formed in 1967 to compete against the NBA, but was actually a long-term plan to merge its teams with the NBA, which happened (for some of them) in 1976.
* The founder and first president of the ABA went on to form the World Hockey Association in 1972, and was the most successful challenge to the [[UsefulNotes/NationalHockeyLeague NHL]]'s dominance in North American hockey and helped bring down the NHL's reserve clause. The WHA administration refused to incorporate the reserve clause (which allowed a club to extend a player's contract by a year when it expired and do so indefinitely, effectively binding a player to one club for his entire career) and set a then-landmark $2.7 million salary for Bobby Hull. Though the league didn't survive past the end of the Seventies, four of its teams merged with the NHL.
* The National Hockey League was the result of a long-running dispute in the predecessor National Hockey Association between Eddie Livingstone, principal owner of the Toronto Shamrocks and Toronto Blueshirts, and the other owners of the league (Montreal Canadiens, Montreal Wanderers, Ottawa Senators, and Quebec Bulldogs). The other owners realized the NHA's constitution meant they couldn't expel Livingstone, but [[LoopholeAbuse they could vote to suspend the NHA]] ([[LoopholeAbuse they could vote to suspend the NHA officially because too many of their players were overseas fighting in]] UsefulNotes/WorldWarI) [[LoopholeAbuse and then form the National Hockey League where those owners could keep Livingstone out]]. Which is what they did in 1917.
* The NFL has been challenged by several rival leagues, among them the American Football League, the United States Football League, both versions of Wrestling/VinceMcMahon's XFL, and the Alliance of American Football. Of these challengers, the AFL was successful enough that it eventually merged with the NFL without losing any teams, and led to the creation of the biggest event for the sport, the UsefulNotes/SuperBowl. The others... not so much (the USFL was successful enough in a few areas that the NFL later added expansion teams in those places (the USFL name was later revived in 2022 for a minor league football organization co-owned by Fox Sports), but the first XFL was highly gimmick-driven and taken seriously by approximately nobody; the Alliance of American Football, while having tons of potential, crashed and burned due to legal issues; and the second XFL would have been an effective [[UsefulNotes/COVID19Pandemic COVID-19]] casualty if it weren't for a group led by Wrestling/DwayneJohnson buying the league out of bankruptcy).
** The genesis of the American Football League in particular is a perfect example of this trope: In 1959, the National Football League had only twelve teams, had no interest in expansion and only one team - the then-Chicago Cardinals - was considered to be on the market. Texas oilman Lamar Hunt had a meeting with Cardinals general manager Walter Wolfner (husband of team owner Violet Bidwill) who basically blew Hunt off. Wolfner bragged that they had suitors from all over the country, mentioning groups from Denver, Houston and Minneapolis, so he really didn't need to deal with Hunt. As Hunt flew back to Dallas, he realized that if there were really that many parties trying to get into pro football, there was no reason they couldn't just start a new league. The eight-team AFL debuted a year later, and quickly became a league to rival the NFL. The documentary ''Series/FullColorFootball'' has the story in greater detail.
* Australian television magnate Kerry Packer attempted to buy UsefulNotes/{{Cricket}} broadcasting rights from the Australian Cricket Board in the 1970s, but they refused, so Packer formed World Series Cricket, signing many of the players from Australia, England and the West Indies.
* Similar to the Dallas Cowboys example, and also crossing over with CreateYourOwnVillain, when the Cleveland Browns fired Coach Paul Brown, who the team is ''named after,'' he joined the new AFL and formed the cross-state Cincinnati Bengals, who not only are the Browns' second biggest rival behind the Pittsburgh Steelers, but also will [[NeverLiveItDown never let Cleveland forget this]] by playing their home games at ''Paul Brown'' Stadium. It should be noted that, at the time of the Bengals' inception, Brown knew the AFL/NFL merger was a done deal and that the ensuing league realignment meant his new team would likely be placed in the same division as Cleveland.
* When the [[UsefulNotes/BritishFootyTeams English football team]] Wimbledon F.C. decided to relocate to Milton Keynes in 2002, a lot of Wimbledon fans were rather upset. In response, they formed their own club, AFC Wimbledon. In less than a decade, the new club had made it into the Football League, and in 2014, they beat the relocated "Milton Keynes Dons" in a cup match. Then AFCW joined MK Dons in League One (the third level) in 2016, and in 2018, [[AndThereWasMuchRejoicing there was much rejoicing]] throughout England as MK Dons were relegated to League Two, meaning that in 2018–19, AFCW would play at a higher level than MK Dons for the first time. Though that only lasted one season; MK returned to League One for 2019–20, and both remain at that level in 2020–21.
** In 2005, a group of Manchester United fans unhappy about Malcolm Glazer's takeover founded their own club, FC United of Manchester. FC United are, as of 2015-16, in the sixth tier of the league.
** A much older and more prominent example: when Everton were first founded, they played their home matches at Anfield. In 1892, after a dispute over rent, Everton left to go play at Goodison Park instead and Anfield's owner, John Houlding, decided to make his own team. He thus founded Liverpool F.C. with some of his old Everton friends, and one of English football's fiercest rivalries was born. Other teams in Europe, such as Italy's Inter Milan and Spain's Real Betis, were founded in a similar way.
* When The Olympic Games decided to drop baseball and softball in 2005, the International Baseball Federation (IBAF)[[note]]since merged with softball's former governing body to create the current World Baseball Softball Confederation (WBSC)[[/note]] along with pro leagues from all over the world (including America's Major League Baseball and Japan's Nippon Professional Baseball) started their own large-scale international tournament, [[https://en.wikipedia.org/wiki/World_Baseball_Classic the World Baseball Classic.]]
* [[UsefulNotes/NationalBasketballAssociation Pat Riley]] spent five years as the head coach of the New York Knicks, building his team into a gritty, grind-it-out playoff powerhouse. Known for their physical play and rough fouls, they made it to the NBA Finals in 1994, where it took the full seven games before the Houston Rockets defeated them. That, along with several other heartbreaking losses, prompted Riley to step down as coach of the Knicks. Instead of retiring, however, he took the reins down at South Beach, where he became the head coach and team president of the Miami Heat. However, like the Paul Brown example above, Riley crossed it over with CreateYourOwnVillain; the Knicks became the biggest reason as to why he couldn't win a championship in the late 90s, eliminating the Heat three straight years after making the Conference Finals against the Bulls. Unlike the Knicks, however, Riley stuck around, and although it took a while, he finally did achieve what he couldn't with New York - a championship to Miami.
* A very common way for new UsefulNotes/{{NCAA}} conferences to form, with several schools breaking away from one conference to start another. Both the Southeastern (1933) and Atlantic Coast (1953) conferences were created by large breakaways from the Southern Conference (and became {{More Popular Spinoff}}s). The modern Pac-12 started after several schools were kicked out of the old Pacific Coast Conference (but eventually most of the remaining PCC members joined the new conference). Then there's this RecursiveReality situation: In 1938 several schools left the Rocky Mountain Athletic Conference to start the Mountain States/Skyline Conference. In 1961, most of those schools joined with a few others to start the Western Athletic Conference. Then in 1999, eight WAC schools broke away to form the Mountain West Conference.
** The current iteration of the Big East conference came about this way: Originally started in 1979 as a northeastern basketball-centric conference, the conference was slowly taken over by the football-playing schools. The non-football playing (and, co-incidentally all Catholic) schools [[note]]DePaul, Georgetown, Marquette, Providence, Seton Hall, St Johns, and Villanova (who does play football but on the FCS/1-AA level), along with league newcomers Butler, Creighton and Xavier[[/note]] (many of whom were original Big East members) tired of being treated as the conference little brothers, so broke away to form their own non-football conference, and took the Big East name and legacy with them (including conference records and the automatic bid to the NCAA Tournament). The remaining football schools [[note]]including UConn, the sole remaining founding member of the (now-former) Big East, and former conference mainstay Temple, who had just returned from the Atlantic 10[[/note]] scrambled to reform, poaching the strongest schools from Conference USA [[note]]Central Florida, East Carolina, Houston, Memphis, Southern Methodist, Tulane and Tulsa[[/note]](most of whom were trying to increase their football programs' profiles) along with the Naval Academy as a football-only member [[note]]They were independant for football and continue to play in the Patriot League for all other sports[[/note]] to form the American Athletic conference.
* Facing sponsor pullout, the J. League side Yokohama Flügels hastily arranged a merger with cross-town rival Yokohama Marinos in 1998 to form Yokohama F. Marinos. A significant portion of Flügels' fans, however, refused to change their allegiance to merged side and considered Flügels to have dissolved instead. What they did, then, was to fund a new club--Yokohama FC--to take over Flügels' place.

!!Politics
* Finland. The duchy of Finland had been a part of the Swedish kingdom until 1809, when Russia conquered and annexed her after a war. When UsefulNotes/TheRussianRevolution started and the Czar abdicated, a power vacuum was created in Finland. The bourgeoisie and the intelligentsiya wanted to stay with Russia; the nobility wanted to re-join Sweden. [[TakeAThirdOption In the end,]] Finland eventually declared herself an independent state 6th December 1917.
* This is notoriously commonplace with left-wing and socialist groups, who always seem to have trouble sticking together when disagreements arise. To wit: The Party for Socialism and Liberation, a major Marxist-Leninist organization in the United States, was split off from the Worker's World Party, and the Worker's World Party split off from the Socialist Workers Party, the Socialist Workers Party split off from the Communist Party USA, the Communist Party USA split off from the Socialist Party of America, and the Socialist Party of America split off from the Socialist Labor Party of America!
* In 1824, Andrew Jackson won the popular vote in the United States presidential election as one of four candidates running under the banner of the Democratic-Republican Party, but the Electoral College was split. The party elite in Congress ended up awarding the presidency to Jackson's rival, John Quincy Adams. In response, Jackson founded his own party, the modern Democratic party, and ran against Adams four years later, winning in a landslide.
** And in response to ''that'', other elements of the disintegrating Democratic-Republican Party formed the Whig Party in 1833 to oppose Jackson. 15 years later, the Whigs were split over the issue of slavery which caused some of the anti-slavery Whigs to start their own Free Soil Party. Then in 1854, with both of those parties failing, former Free Soilers and northern Whigs got together to have another go at starting their own party: the modern Republican Party.
** The Democratic party also split over the issue of slavery, resulting in the 1860 election (won by Abraham Lincoln) featuring four major presidential candidates, including two Democratic candidates and a "Constitutional Union" candidate. Unlike the Republican party, the Democratic party sort of healed their rift after the Civil War, only to split 80 years later over the issue of Civil Rights. However, the Dixiecrats - the Southern Democrats - rather than forming their own party, instead gradually took over the Republican party.
* This trope is credited as one of the reasons that Libertarianism (in the [[UsefulNotes/AmericanPoliticalSystem American sense]]) has so much trouble becoming a party with any real power. There are simply too many different groups that consider themselves Libertarian to ever organize.
* UsefulNotes/TheodoreRoosevelt disliked UsefulNotes/WilliamHowardTaft and the growing conservatism of the formerly moderate Republican party (and felt personally betrayed by his former protege Taft's role in that rightward shift), so after a failed attempt to unseat Taft as the Republican nominee (few states held primaries in that era, so party bosses had almost complete control over the nominating process and they were firmly in Taft's corner) he started his own progressive liberal party in 1912, known informally as the Bull Moose Party. As with all United States third parties, it failed and instead split the vote so the [[UsefulNotes/WoodrowWilson Democrat]] won.
** That was Roosevelt's intention. He hated Taft's policies and would have rather seen a Democrat win than Taft get re-elected. [[HangingSeparately So he created the new party to sabotage Taft]]. And in the process he left Taft with the ignominy of being the only incumbent US president to finish ''third place'' in his reelection bid.
** Despite the failure of the Bull Moose movement, most of its adherents threw in their lot with the Democrats after Franklin Roosevelt - 5th cousin of Theodore - announced the New Deal policy platform in the 1930s.
* The 13 British colonies in North America had a bit of a problem with the mother country's bad habit of forcing legislation (and taxation) on them without their permission (since it would be too much of a hassle to ship American politicians across the Atlantic to Parliament), so they decided to start their ''own'' independent government, with an eye towards fixing all the grievances they had with Britain. Britain of course took exception to that, the Americans took exception to their exception, the Americans won, and history was made.
** And of course the UsefulNotes/AmericanCivilWar was a failed attempt by the rebellious southern states to form a new country due to fears that the country would restrict or ban Slavery (and a bunch of other, minor political and social tensions as well). The same conflict led to the creation of the state of West Virginia, when it turned out that those Virginians living in the Appalachians wanted nothing to do with the whole 'slavery' or 'secession' stuff and decided to secede from Virginia and rejoin the glorious 'murrikan motherland.
* Even Al Qaeda [[http://bigstory.ap.org/article/ap-exclusive-rise-al-qaida-saharan-terrorist is not immune to this]], with [[http://www.huffingtonpost.com/2013/05/28/moktar-belmoktar-terroris_n_3349176.html Moktar Belmoktar]], a former disgruntled employee starting his own terrorist group after Al Qaeda wrote him a scathing letter accusing him of, among other things, failing to carry out a single operation, not filling out expense reports, not attending meetings [[ArsonMurderAndJaywalking and not answering his phone when they called]].
* Political parties, especially those positioned far from the center, usually start out this way with some radical from a more "grounded" party feels their party sold out and breaks off from it. For example, every left wing organization or party in Sweden, be they democratic socialists, syndicalist or outright Stalinist descends from the left-to-center-left Social Democratic party in one way or the other.
** Similarly, high profile members of far-right parties in the UK have a habit of suddenly deciding that the party is too moderate for their tastes and splitting off to form parties more in keeping with their personal ideals. Prominent examples include former British National Party members Paul Golding and Jayda Fransen, who split away to form Britain First, and would-be UKIP leader Annie-Marie Waters, who suffered a surprise defeat in the 2017 UKIP leadership election, and subsequently stormed out of the party and formed For Britain.
** A recent example from Canada: In September 2018, Conservative leadership runner-up Maxime Bernier, disgruntled with actual new party leader Andrew Scheer not being hard enough on immigration for his tastes, quit the Tories and founded the People's Party of Canada, a party with much the same views as the Conservatives but with a more libertarian, populist and, of course, anti-immigrant stance.
* In the Philippines, the Liberal Party got its start in the 1940s as a splinter-off faction of the Nacionalista Party (virtually the only party in power at the time, as the country/semi-US-colony was essentially a one-party state). Disgruntled party members, chief among them Manuel Roxas (who would go on to be President in 1946), left and started their own party to challenge the Nacionalistas at the polls. Not that it really mattered party-wise, because the two parties differed very little in ideological leaning, and party-switching or "turncoatism" was rife—a reality that still holds today under an ostensibly multiparty government. The Liberals in fact were the originators of the "start-your-own-party" trend regardless of ideology or beliefs.
* Benito Mussolini was originally a leader in the Italian Socialist movement, but soured on the group as they took an anti-war stance during UsefulNotes/WorldWarOne (Mussolini thought that a war would accelerate the socialist movement and allow for the overthrow of the old order). After getting kicked out of the Socialists, Mussolini formed the Fascists to cater to soldiers and strongmen who felt Italy had been cheated out of its reward for assisting the other members of the Entente, and they would go on to dominate Italian politics until UsefulNotes/WorldWarTwo

!!Education
* This is how Cambridge University was formed. A bunch of students were kicked out of Oxford, made their way across the country, and started their own university.
** This is also how University College London, the third university to be founded in England after Oxford and Cambridge, came into being. Unlike Oxford and Cambridge, it was entirely secular and allowed women in on an equal footing with men, inspired by the (then) radical philosophies of [[http://en.wikipedia.org/wiki/Jeremy_Bentham Jeremy Bentham]].
** The University of Bristol was genuinely founded by a man whose son failed to get into Oxford. The original 'college' is now the Physics Department.
* Several current universities in UsefulNotes/{{Shanghai}}, or their predecessors, were founded that way during the first half of the 20th century:
** In 1902, some students left the Nanyang Academy (predecessor of Shanghai and Xi'an Jiaotong Universities) over what they perceived as unfair treatment of one disciplinary action, and their sympathizers arranged them to study European philosophy from Rev. Ma Xiangbo, a Chinese Jesuit monk. These students became the first students of Aurora University, a Jesuit university founded the following year under Rev. Ma's behest. However, in 1904, Rev. Ma ResignedInProtest with a group of students as the Jesuits wanted to dissolve the student government--and went on to found Fudan University.
** The two major predecessors of East China Normal University were also founded this way:
*** In 1924, the president of Xiamen University mentioned respect for Confucianism in a public speech, which did not sit up well with the college's radical elements, who left for Shanghai to found Great China University.
*** St. John's University was an Episcopal college known for being very good, very expensive, and ''very'' politically conservative, and predictively was not pleased with its pro-labor elements during a major labour movement in 1925. As a result, 19 members of the faculty and more than 500 students left to found Kwang Hwa University. Ironically, the main bulk of St. John's was forcibly merged into ECNU, which formed from a less-than-voluntary merger between Great China and Kwang Hwa.

!!Clubs
* A couple of the early 20th-century industrialists started their own golf clubs, university endowments, etc., because they kept getting shunned by old money families.
** In the same way, New York City's grandest palazzo, the Metropolitan Club, was organized by J. P. Morgan in protest against not being admitted to some of the city's other exclusive private men's clubs. He showed ''them''.

!!Religion
* Quite a few Christian sects got started because of this trope:
** The Religious Society of Friends, better known as the Quakers, who formed their own sect of Christianity because its founder, George Fox, objected to the Anglicans' emphasis on ceremony.
** Martin Luther was excommunicated from the Roman Catholic Church. So he started his own church! With beer! And wives for the clergy! [[CorruptChurch And no corruption!]]
** Henry VIII wanted to divorce his wife, Catherine of Aragon. When the Pope refused to annul Henry's current marriage, Henry formed his own church, the Church of England, installed himself as its head, and divorced her anyway.[[note]]Also, Catherine had been his brother's widow, meaning by the convention of the time his father had needed a special papal ruling to allow him to marry her at all, making his annulment request a bit hypocritical.[[/note]]
** The Baptist church in the United States in the 1800s favored abolition of slavery. The Southern Baptist church splits off in 1845 as an explicitly pro-slavery sect.
** The Free Methodist Church's name comes from their abolitionist roots. That, and their refusal to charge for seats.
** Christian humorist Adrian Plass, in one of his novels, mentions the concept of church groups splitting so often that some people are in danger of dissenting themselves right back to where they started...
** Mormon Fundamentalists are what happens when, thinking mainstream Mormons were wrong to abandon polygamy, more radicalized Mormons start their own. This came about, mind you, after Joseph Smith did the same thing to Christianity. (Although UsefulNotes/{{Mormon|ism}}s would disagree with labeling their church as reformed.)
** The Episcopal Church in the US went through this following the election of a gay divorced man as bishop of New Hampshire. This caused many conservative Episcopal parishes to separate themselves into the Anglican Church in North America. For the time being the Episcopal Church retains membership in the international Anglican Communion (though relations are strained) and the ACNA has not been granted full communion (although some churches within the Anglican Communion are in full communion with ACNA instead of the Episcopal Church).
** The Metropolitan Community Church in the US was founded by ex-Baptist/Pentecostal preacher Troy Perry in protest against the Christian attitudes toward homosexuality at the time.
** The ''[[https://en.wikipedia.org/wiki/Raskol Raskol]]'' was in protest of changes of the liturgy by the Patriarch Nikon.
** The [[https://en.wikipedia.org/wiki/Church_of_the_East Church of the East]] was created after the [[https://en.wikipedia.org/wiki/First_Council_of_Ephesus 431 Ephese Second Council]].
** And, of course, the OlderThanPrint TropeMaker of religious schisms, [[http://en.wikipedia.org/wiki/East%E2%80%93West_Schism the Great Schism]], whereupon the Roman Catholic and Eastern Orthodox Churches went their separate ways.
** Christianity ''itself'' is this trope embodied. It all started when the Rabbinic Judaism declared the Messianic sects as heretic in the synod of Yamnia 90 AD. The Messianic sects of Judaism then unified and became Christianity, which was organized under the successors of St. Peter as Catholic Church.

!!Arts
* In the art world of the 1860s, the [[http://en.wikipedia.org/wiki/Salon_des_Refuses Salon des Refuses]] was started in Paris by a group of artists, now referred to as the Impressionists, who were infuriated at being constantly rejected by the official Salon de Paris.
** The Secession movement in Vienna, for much the same reasons.
* The Metropolitan Opera Company was founded by a group of businessmen who were annoyed by being unable to obtain box seats at the Academy of Music.

!!Technology
* An early example in the technology world was a group of engineers known as the "Traitorous Eight" who worked under William Shockley, the inventor of the transistor. Irritated by Shockley's increasingly erratic behavior and iron-fistedness, the Traitorous Eight quit and formed Fairchild Semiconductor, which in turn spawned Intel.
* This is also true for software, especially [[http://www.gnu.org GNU]] and the [[http://www.fsf.org/ Free Software Foundation]]. Half of the software listed on [[http://sourceforge.net SourceForge]] would not exist without this trope, though it's usually spurred on by avoidance of restrictive licenses. Where religions have schisms, free/open-source software has "forks". Granted, this trope is at the heart of FOSS software: according to their philosophy, anyone who thinks they ''can'' do better should be given the opportunity to [[LetsSeeYouDoBetter prove it]].
** In the BSD world, [=OpenBSD=] and [=DragonFly=] BSD owe their existence to the fact that their founders had disagreements related to the development of [=NetBSD=] and [=FreeBSD=], respectively.
** Allegedly, one of the main reasons ''Linux'' came about was because Linus Torvalds was becoming increasingly frustrated with several of the design decisions that went into the design of ''Minix'', a payware educational Unix distribution for personal computers, that he was forced to use at college. He then managed to get into a heated argument with the creator of the distribution while he was airing his greviences on usenet. After his pride was badly torn up by the creator and his fanboys, Linus decided to start his own, and the rest is history.
** Also, the main reason ALSA (Advanced Linux Sound Architecture) was created was because the OSS (Open Sound System) team had announced that they were going to split their driver packages into two- a free package for the most common consumer cards and a paid-for package for the higher end prosumer and professional sound cards. The Linux developers, whose motto was to have Linux running on ''everything'', were repulsed and thus started their own.
** As a side note, a different issue with OSS' drivers, namely lack of security, was what gotten the [=OpenBSD=] developers to create their own OSS-like set of drivers.
** When dying computing conglomerate and open-source champion Sun Microsystems got bought over by the database megacorp Oracle, Oracle proceeded to discontinue [=OpenSolaris=] several weeks later, barely hiding their greed and hinting that people who want to continue using Solaris will now be subjected to either a crippled free version called ''Solaris Express'', or have to pay up for a full version, where previously [=OpenSolaris=] was completely feature-compatible with the paid Solaris system save for the lack of tech support. Thing is, the license for [=OpenSolaris=] allowed the last version produced before Oracle shut the gates to the source code to remain free. The biggest contributors took the last version of the OS and forked, and ''illumos'' was born. [[note]]This is also a case of CreateYourOwnVillain, as the team originally had no plans to fork until Oracle decided to give them the finger.[[/note]]
** At the same time as it screwed the [=OpenSolaris=] community, Oracle's behavior stifled the development of [=OpenOffice=]. Many of their developers were laid off or left on their own accord, they went on to form The Document Foundation and fork [=OpenOffice=] into [=LibreOffice=]. Oracle did eventually just give [=OpenOffice=] away to the Apache Foundation, but that only created a bitter FandomRivalry as a result.
** And to show that things come in the power of three, Oracle buying up Sun also gave them control of the [=MySQL=] database engine, which they then proceed to cripple as to prevent the free option from competing fairly against their flagship product. Again, many devs left and forked the last Sun-produced version, this time into [=MariaDB=].
** Another high-profile fork in the open-source community was the FFMPEG[=/LibAV=] schism in the software project that underlies nearly all video-related open source applications. Emerging from political turmoil within the FFMPEG project, the effects of the split the sent shockwaves through the broader open-source community, particularly Linux users, due to Ubuntu (one of the most popular distributions) initially siding with Libav. [[note]](see [[http://blog.pkh.me/p/13-the-ffmpeg-libav-situation.html here]] for further commentary, though it's a bit old).[[/note]] More than half a decade later, the two projects are still developed separately, with Libav pointedly ignoring FFMPEG's existence and FFMPEG continuing to expend effort to merge Libav's improvements back into itself in addition to doing its own development. The turmoil surrounding the issue has ceased, however, since most of the projects that initially sided with Libav have since gone back to FFMPEG.
** Another heated one with the GNOME desktop project. When it was revealed that GNOME 3 was going to take a page out of Windows 8's book by doing away with a start button metaphor for a start screen metaphor designed for both desktops and tablets, a subset of the developers were vocally (and understandably) opposed to this on the grounds, that Microsoft were regretting doing that: The intention was to design a user interface that was optimised for mouse-and-keyboard ''and'' touchscreen operation but the result an interface that [[MasterOfNone was sub-optimal for either]]. This led to two forks- ''MATE'', which forks GNOME 2 with the intention of keeping the immediate interface but keeping the underlying libraries upgraded to the latest, and ''Cinnamon'', which takes GNOME 3 but deletes the undesirable features while porting desired features from GNOME 2 back into it. [[AuthorsSavingThrow The developers of GNOME eventually gave in and created an official GNOME 2 mode for the desktop environment]], called ''GNOME Flashback''.
** And this is happening again with the XFCE project, a ''[[TakeAThirdOption third option]]'' taken by some who hated GNOME 3 but did not want to wait for ''MATE'' or ''Cinnamon'' to mature as it was started as an attempt to create a GNOME 2 clone that is light on resources. When the newly appointed head of development proved himself to be a prima-donna and wanted to change XFCE to clone GNOME 3 (specifically, the hated elements like the start screen and the location of the save/open button in the file chooser) ''and specifically started to vocally attack anyone who protested the idea'', a group of developers have immediately schism themselves from the main project and forked the current version to ''XFCE Classic''.
** A unique case: The creators of LXDE, another GNOME 2 clone that focuses on being lightweight, decided to switch from the ageing and depreciated [=GTK2=] [[https://en.wikipedia.org/wiki/Widget_toolkit widget toolkit]] to [=Qt=] instead of [=GTK3=], and forked themselves into [=LXQt=]. Work was stopped on LXDE proper and the project was officially abandoned, and users were advised to switch over to the new project. Not everyone was okay with this, as [=Qt=] uses a lot more system resources; not enough to be a problem on the majority of modern hardware, but an issue for devteams who create ultra-lightweight Linux distros designed to keep exceptionally old and underpowered [=PCs=] usable. Some of those devs assumed control of the original project and recommenced development using the newer [=GTK3=] library, and now LXDE and [=LXQt=] are two separate projects, with the latter becoming an officially recognized fork of the former.
* Microsoft created the [=C#=] programming language, which is similar to Java in many ways, after Sun Microsystems refused to allow them to create a customized version of Java to bundle with Windows, fearing that it would be subject to Microsoft's [[https://en.wikipedia.org/wiki/Embrace,_extend,_and_extinguish "extend, embrace, extinguish"]] strategy.
* [[http://www.reactos.org The ReactOS project]], an open-source Windows clone, began as a reaction to some of the more questionable business practices of Microsoft. [[MeaningfulName It's also how it got its name.]]
* Seymour Cray was a star employee of Control Data Corporation during the mainframe computer era - until management turned down his proposal for a next-generation super-computer. Cray quit and formed his namesake super-computer company, which Control Data - at the time one of '[[https://en.wikipedia.org/wiki/BUNCH IBM and the Seven Dwarfs]]' - never fully recovered from.
* After UsefulNotes/SteveJobs was KickedUpstairs at Apple due to his stubborn personality rendering him unable to get along with anyone else in the company, he decided to quit and form a new computer company, called [=NeXT=], which was basically every stereotype about Apple turned up a notch. Its products generated a lot of buzz for their ease-of-use, technical sophistication, and striking aesthetic designs, but they were also [[CrackIsCheaper ludicrously expensive]] and [[NoBackwardsCompatibilityInTheFuture not compatible with any existing products]] [[note]]Bill Gates famously quipped "[=NeXT=] has an interesting feature called incompatibility"[[/note]]. This came at a time when the industry was rapidly embracing the standards set by the UsefulNotes/IBMPersonalComputer, which also had the effect of driving costs down, leading to poor sales of [=NeXT=]'s computers. Ironically, [=NeXT's=] legacy would be salvaged when Apple purchased them in 1997 in order to use their [=NeXTSTEP=] operating system as the basis for what became Mac OS X, bringing Jobs back to Apple in the process. Though at first he only held the position of "advisor", he quickly rose to the position of CEO, which he held until shortly before his death in 2011.
* Developer byuu created the bsnes and higan UsefulNotes/SuperNintendoEntertainmentSystem emulators, which are designed to be 100% accurate to the original console[[note]]Meaning they mimic the behavior of the system exactly, as opposed to other emulators which to varying degrees sacrifice accuracy in order to improve performance[[/note]] after the developers of ZSNES, a popular SNES emulator, refused to patch an inaccuracy in their emulator[[note]]To put things from ZSNES' perspective, patching that inaccuracy would impact performance. ZSNES was hand-crafted in machine code to use very little resources and CPU power such that even SuperFX and DSP-1 games can run at playable speed on a lowly Pentium 166 machine, and part of that includes several speed "hacks" that introduces inaccuracy in favor of speed. BSNES and it's accuracy-favoring engine on the other hand requires a very fast and modern multi-core machine to run.[[/note]]
* Brendan Eich started development of the privacy-focused [[https://brave.com/ Brave]] Internet browser after being fired from Mozilla when his donations to an anti-gay marriage group came to light.
* Huawei launched their own mobile services framework called Huawei Mobile Services (HMS) as a substitute for Google Play Services, as well as their own app store called [=AppGallery=] after Google stopped providing software support to Huawei due to US government sanctions; the [=AppGallery=] has existed prior to the company being sanctioned in 2019, though it was only available in China until 2018. For the remaining apps which couldn't be published to the [=AppGallery=] due to sanctions or some other reason, they even came up with [[https://www.huaweicentral.com/huawei-introduces-new-solution-to-install-third-party-apps-on-huawei-phones-with-open-source-android/ workarounds]] such as directing users to download APK installation files from mirror sites such as [=APKPure=], though compatibility may be hit-or-miss as some apps may require specific Google [=APIs=] to function correctly.

!!Sports
* Adidas and Puma, two rival sport shoe companies, began as one company founded by brothers Adolf "Adi" Dassler and Rudolf Dassler. After the two had a violent fall out in 1948, the original company folded, with Adi founding Adidas and Rudi founding Puma. Their home town of Herzogenaurach became fiercely divided between the two brands, even the two football clubs; one was sponsored by Adidas, the other by Puma. The hatchet was ''finally'' buried in the late 2000's with a Peace One Day-sponsored soccer match, however Adidas and Puma remain independent concerns. Meanwhile, the brothers remained bitter rivals to their deaths (events like [[TechnicianVersusPerformer the original shoemakers going with Adi and the original management going with Rudi]] and [[EpilepticTrees each brother trying to denounce the other as a Nazi to the Americans after WWII]] certainly didn't help), and while they're now buried at the same graveyard, their graves are as far away from each other as possible.
* Garry Kasparov split from FIDE, the World Chess Federation, to form the PCA (Professional Chess Association) in 1993.
* This happens a lot in martial arts, especially after a particular organisation's founder has died. Often, a successor is chosen and many of their other protégés may disagree with this. There can often be other reasons as well, such as differences in what way the martial art chooses to (or not to) evolve or even [[MoneyDearBoy what membership dues are required]].
* UsefulNotes/BrazilianJiuJitsu was this to UsefulNotes/{{Judo}}, although initially unintentionally — Hélio and Carlos Gracie both learned a martial art their Japanese-immigrant teachers simply called "Jiu-Jitsu" and affirmed they didn't heard the term "Judo" until the 1950s and thought they were doing the same "Jiu-Jitsu" that was done in Japan — however, they decided to "split" and not adopt the Kodokan rules when they were introduced in Brazil, and in 1967 they (along with other 4 schools of Alvaro Barreto, Joao Alberto Barreto, Hélcio Leal Binda, and Oswaldo Fadda) founded the Jiu-Jitsu Federation of Guanabara with their own ruleset. The term "Jiu-Jitsu" served to differentiate it from Judo.
* Examples in UsefulNotes/{{Bodybuilding}}:
** The World Bodybuilding Federation was created in 1990 by then-Wrestling/{{WWE}} (then the World Wrestling Federation) owner Vince [=McMahon=] with help from veteran bodybuilder Tom Platz, with the intention of challenging the dominance of the [=IFBB=] while also mixing in elements of pro wrestling, such as competitors being given ring names and kayfabe personas that were showcased in entertainment-based segments of [=WBF=]'s media. Despite hiring away a number of [=IFBB=] competitors, the [=WBF=] ended up folding after only a short period of time due to varying reasons, with many [=WBF=] members allowed to re-join the [=IFBB=] after paying a fine.
** The [=IFBB=] Elite Pro league split from the [=IFBB=] Pro league in 2017. Many reasons had been cited for the split, including alleged personal rivalry between IFBB President Rafael Santonja and NPC President Jim Manion. Contestants have to choose either league to compete in, not both. The traditional Olympia competitions remained linked to the Pro league.
* [[https://en.wikipedia.org/wiki/Bill_Powell_(golf_course_owner) Bill Powell]], after being banned from local golf courses due to racial segregation, designed and built the first integrated golf course in 1948.

!!Business
* Ferrari is involved in ''three'' examples:
** First, inter-company politics in the early sixties led a group of engineers to jump ship and form their own company, ATS. Unfortunately, their first effort came across as lackluster and they folded after a couple of years. However, they were revived in TheNewTens.
** In the mid-sixties, Ferruccio Lamborghini, president of what was then primarily a tractor manufacturer, came to Enzo Ferrari to complain that his recently purchased Ferrari had a faulty clutch. He also explained that he had tried the clutch from one of his own tractors in the car and it worked fine. A fierce argument followed, and Lamborghini looked through his car some more and decided that his company already had the ability to make most of the necessary components for a luxury automobile. The rivalry continues to this day.
** In 1963, Ferrari was desperate to secure funding, and the company entered serious talks with Ford about purchasing the company. When Enzo Ferrari learned that the Americans wouldn't allow him to keep control of the racing team, he broke off the negotiations. Ford (and Henry Ford Jr. in particular) was so incensed that they designed the [=GT40=] specifically to challenge Ferrari's record in the 24 Hours of Le Mans. The [=GT40=] went on to win Le Mans four times in a row. This event was dramatized by the 2019 film ''Film/FordvFerrari''.
* Music/SeanCombs was fired from Uptown Records during the early 90's. Afterward he formed his own label, Bad Boy Records. The latter is more or less still thriving while Uptown folded.
* Dave Thomas (the restaurateur, not the actor) made a name for himself as assistant to Colonel Harland Sanders. Had he stayed in line, Thomas would probably end up inheriting the reins of KFC, but due to personal disagreements with the good Colonel, Thomas struck out on his own and founded his own restaurant chain, which he named after his daughter Wendy.
* When Brazilian movie magazine ''SET'' was sold to a different publisher, one of the editors went to start its own publication, ''Preview''. Both had a FandomRivalry until ''SET'' went under.
* Boyd Coddington's hot rod shop, Hot Rods by Boyd, faced bankruptcy in 1998. So, president Chip Foose left to form his own company, Foose Design. The two companies endured a fierce rivalry right up until Boyd Coddington's death ten years later.
* Creator/CarpeFulgur, the company responsible for the localization of ''VideoGame/RecettearAnItemShopsTale'', was founded by two guys trying to get into the localization business only to be constantly turned down due to lack of experience. So they decided to create their own company to earn that experience.
* The United Services Automobile Association started as an insurance co-op formed by a group of American Army officers who couldn't get car insurance. Over the decades it has gradually expanded to become a rather successful financial institution offering insurance, banking, and various other services to American military personnel and their families.
* When Creator/TheWB and Creator/{{UPN}} decided to merge and become Creator/{{The CW}}, the new network did not include any of the UPN affiliates owned by Fox (including many of the big-market stations). In response, Fox created a new network for these stations, Creator/MyNetworkTV.
* A (possibly apocryphal) story has it that the founder of Netflix did so after his outrage over a $40 Blockbuster late fee inspired him to start his own video rental service. [[Series/HouseOfCardsUS With blackjack!]] [[Series/OrangeIsTheNewBlack And hookers!]]
* A RealLife example of a fed up customer starting their own - [[https://web.archive.org/web/20220827084158/https://www.npr.org/2022/08/22/1118734792/michigan-man-isp-fiber-internet Fed up with ISPs, a Michigan man started his own fiber broadband service]].
* This was essentially what led to the creation of the [[http://en.wikipedia.org/wiki/Dassault_Rafale Dassault Rafale]] - France was originally collaborating with the UK, Germany, Italy and Spain on the Eurofighter project, but they wanted to make a carrier-capable version; when it became clear that none of the other countries wanted to bother with one, France withdrew to pursue their own project. Similar to many other examples of this trope, the Rafale actually entered service before the Eurofighter.
* The ice cream chain [=KaleidoScoops=] was started in 1999 by a bunch of Baskin-Robbins owners who had their franchises terminated due to underperformance.
* During the 1920's, Piggly Wiggly faced a decrease in business in Florida, which forced the chain's owner to sell his stores. A businessman in Atlanta purchased them, but chose not to visit the stores. One of the chain's managers, George W. Jenkins, decided to visit the new owner personally so that they could discuss the future of the business. But when Jenkins got to Atlanta, he was told the new owner was unavailable to talk due to a "critical business consultation". Jenkins overheard the new owner discussing his golf game over the phone, which only enraged him. Jenkins returned to Florida and started his own business, Publix Supermarkets, in order to compete against the new owner of Piggly Wiggly.
* In 2018, the founder of Nuclear Blast Records, Markus Staiger departed from the label following the label's acquisition by Believe Digital. The split resulted in Staiger founding the label Atomic Fire Records in 2021 while transfering roughly a dozen bands from his former label over to the new label. Additional bands have since been signed such as [=U.D.O.=], [=Power Paladin=], [=Skull Fist=] and [=Mystic Circle=].
* The Colorado-based pizza delivery chain Blackjack Pizza was started by Vince Schmuhl, a former Domino's employee, in 1983 after Schmuhl decided to open his own chain to provide an alternative to Domino's; which had been the only major delivery chain in the Rocky Mountain region.

!!Production Companies
* Creator/{{Disney}} as it exists today came about from Creator/WaltDisney losing his contract with Creator/{{Universal}} in 1928. The studio later founded its own distribution company Buena Vista in 1953 after disagreements with its previous distributor [=RKO=] Radio Pictures.
** [[Creator/HarmanAndIsing Hugh Harman and Rudolf Ising]] were two Disney animators who stayed with Universal after Walt Disney left in 1928, and they in turn left Universal in 1929 to form their own studio. In 1933 they teamed up with producer Leon Schlesinger, who got them a contract with Creator/WarnerBros to distribute their new ''WesternAnimation/LooneyTunes'' series. Then in 1934 they left that studio and went to work for Creator/{{MGM}}.
** Charles Mintz, Disney's one-time distributor and the man most responsible for causing Walt to leave Universal in 1928, was himself dropped by Universal in 1929. His response was to fully take over his wife Margaret Winkler's company the Winkler Studio (which he had been ''de facto'' running since 1924), renaming it the Mintz Studio and signing a deal with Creator/ColumbiaPictures to distribute cartoons. Mintz eventually became indebted to Columbia and [[Creator/ColumbiaCartoons lost his studio to them in 1939]], passing away one year later.
** Creator/UbIwerks left Disney in 1930 to create a new studio with Disney's former distributor Pat Powers. Although he pioneered many new animation techniques in his shorts, Iwerks' studio was never profitable and he was dropped by Powers in 1936. After his studio went bankrupt a year later Iwerks retired from animation altogether, opting instead to rejoin Disney in 1940 as the head of their newly-formed research and special effects department.
** Multiple Disney artists who found themselves out of work for taking part in the Disney strike created [[Creator/ColumbiaCartoons UPA]] in 1948, which pioneered the LimitedAnimation technique that was prevalent during UsefulNotes/TheDarkAgeOfAnimation.
*** Multiple animation studios came to be from former UPA staff, including Format Films (best known for [[WesternAnimation/TheAlvinShow the first animated incarnation of Alvin and the Chipmunks]]), Bill Melendez Productions (the ''ComicStrip/{{Peanuts}}'' specials), Pantomime Pictures (''WesternAnimation/RogerRamjet''), and Murakami-Wolf-Swenson (''[[WesternAnimation/TeenageMutantNinjaTurtles1987 Teenage Mutant Ninja Turtles]]''). A book about UPA, ''When Magoo Flew'', suggests that the reason so many studios came to be was because many UPA personnell, disgruntled by Stephen Bosustow's mismanagement, felt they could run a studio better than he can.
** Creator/DonBluth was a Disney animator who was unhappy with the mediocre animated films that the studio was churning out after the death of Walt Disney. He and twelve other animators left Disney in 1979 to form their own animation studio, with the intention of replacing Disney or at the very least providing Disney with some genuine competition to force them to make better movies. The studio ended up succeeding on both fronts: it replaced Disney as the premier American animation studio in the 1980s ''and'' it forced Disney to step up their game... [[GoneHorriblyRight but as consequence]] Disney regained its powerhouse status in the 1990s and Bluth couldn't keep up, leading to the closure of his original studio and then later his second studio.
** After being fired from Disney in 1983 by then-studio head Ron Miller, Creator/JohnLasseter was tapped by Ed Catmull and Creator/SteveJobs to create CGI advertisements for their new line of computers. Lasseter's ad department turned into a short film department after buyers became interested in seeing how extensively the software could be used, and these shorts caught the attention of Jeffrey Katzenberg (who had replaced Miller as Disney's studio head in the mid-1980s). He signed the studio (renamed Creator/{{Pixar}}) to create a series of computer animated films in the early 1990s, and the rest is history.
** Creator/RichardRich left Disney to form Rich Animation Studios in 1985 after disagreements with Disney Animation head Peter Schneider over the direction of [[WesternAnimation/TheGreatMouseDetective his next film]]. Unlike Don Bluth his studio is still around today, but it was never anywhere near as successful as Bluth's was.
** Disney purchased Creator/MiramaxFilms in 1993, in an effort to establish itself in the independent film market. After a rocky decade of relationships with Miramax's heads Bob and Harvey Weinstein (that culminated in Disney refusing to release Miramax's ''Film/Fahrenheit911'' and suspecting that the Weinstein brothers weren't being entirely honest about their studio's profitability in the 2000s), the brothers left Disney to form Creator/TheWeinsteinCompany in 2005. Disney shuttered and sold Miramax in 2010, while The Weinstein Company was thrown into bankruptcy in 2017 following the firing and arrest of Harvey over sexual abuse allegations that spanned decades.
** Jeffrey Katzenberg left Disney in 1994 after arguments with then-CEO Michael Eisner, and went on to co-found [[Creator/DreamWorks DreamWorks SKG]] with Creator/StevenSpielberg and David Geffen. The best-known, most successful part of the company turned out to be Katzenberg's Creator/{{DreamWorks Animation}}. Spielberg's live-action portion, [=DreamWorks=] Studios, had some success in the late 1990s/early 2000s but is much less active today.
** Joe Roth replaced Katzenberg as the Disney Studios chairman and remained in that position until 2000, when he left to form his own production company Creator/RevolutionStudios. He then left that company in 2007 to form a new one, Roth Films.
* Creator/OrionPictures was created by former Creator/UnitedArtists executives who were fed up with its then-owner Transamerica's influence on the company.
* After Creator/{{MGM}} shut down its animation division in the 1950s, animators William Hanna and Joseph Barbara formed their own animation studio, appropriately titled Creator/HannaBarbera.
* Similar to above, after Warner Bros. closed down their animation division Creator/FrizFreleng teamed up with David H. [=DePatie=] (who was managing the division at the time) to form [[Creator/DepatieFrelengEnterprises [=DePatie=]-Freleng Enterprises]].
** When Creator/ChuckJones was fired by Warners just shortly before their animation division closed down, he was hired at the newly reopened MGM animation division. After MGM closed it down ''again'' he formed his own company, Chuck Jones Enterprises.
* Netflix's popularity has encouraged major studios like Disney and Warner Bros to start their own streaming services rather than license their content to Netflix or other services like Hulu or Amazon Prime.
* In the mid-70s, Creator/GeorgeLucas wanted to do a feature-film version of ''ComicStrip/FlashGordon'', so he set out to acquire its rights. But when he was outbid by Dino [=DeLaurentiis=], he decided to create his own space opera, ''Franchise/StarWars''.
** This is a double example. After deciding to create his own movie, Lucas had a ''very'' grand image for the special effects (poor effects being one of the things keeping sci-fi mostly confined to B-movies). When he couldn't find anyone who made the grade, he got together some college buddies and revolutionized special effects with his own company. They're still around today- you probably know them as ''Creator/IndustrialLightAndMagic''.
* This is effectively the story behind the Franchise/MarvelCinematicUniverse: after dealing with flops made by other studios with their characters and only getting a small percentage of the profits the ones that were hits made, Marvel decided to make ''Film/IronMan1'' on their own, and the rest is history. Possibly a subversion since Marvel was later bought by Disney (see above for the numerous studios founded by ex-Disney employees), but Disney has let the MCU function fairly independently.
* Creator/MasiOka decided he wanted to break into the game industry, since he enjoyed playing games and wanted to make some, but the studios he approached with his ideas turned him down. So, he asked a bunch of college kids about to graduate if they wanted to come work for him, and that's how Creator/MobiusDigital got started.
* When the [[CultClassic cult]] online game ''VideoGame/CityOfHeroes'' was shut down [[ScrewedByTheNetwork for some reason]] and NC Soft seemed unwilling to sell it, fans immediately considered developing a replacement, which became ''VideoGame/CityOfTitans''. Less than three months later, even before the original game's shutdown had been completed, founding member Golden Girl started ''another'' project, ''Heroes and Villains'', over CreativeDifferences. ''City of Titans'' will be a [[SpiritualSuccessor Spiritual Sequel]] (as in, revamping the game mechanics to some extent), while ''Heroes and Villains'' is apparently supposed to be ''City of Heroes'' with the SerialNumbersFiledOff.
* This is how the telephone industry got started. When Alexander Graham Bell's initial design was rejected by Western Union, then the leading distributor of telegraph services, he took the design to Joseph Henry, who saw its potential. Western Union tried to cram their patent into the office before Bell did, but eventually gave up, [[ItWillNeverCatchOn believing the telephone to be a minor threat to their telegraph monopoly that would fizzle out soon.]] They ended up shooting themselves in the foot with this decision, as in only 3 years, there were 30,000 sets worldwide, and 2 million sets by 1900. Thus, Western Union ended up being the one to fizzle out (save for use as a money-wiring system) and Bell's telephone company is still around to this day. You might have heard of them: a little company named [=AT&T=].
* This is how Creator/ImageComics came into being. Several artists who worked on most of Creator/MarvelComics's top-selling properties in the late 80's to early 90's, such as Creator/{{Todd McFarlane}}, Creator/RobLiefeld, and Creator/MarcSilvestri, were dissatisfied with how poorly they were treated, in particular not owning any of the properties they created while working under Marvel. In 1992, they all left Marvel to form their own company: Image Comics. Image itself would not own anything other than its name and logo, and published the comics while the creators retained ownership, an arrangement completely unheard of at the time. Image single-handedly revolutionized the comics industry, with ComicBook/{{Youngblood}}'s first issue being the all-time best selling independent comic at the time of its release. At the height of its success, Image actually beat out D.C. in sales, forcing them to take drastic measures like [[ComicBook/TheDeathOfSuperman killing off Superman]] (albeit temporarily) and [[ComicBook/{{Knightfall}} crippling Batman]] in order to keep up with them.
* Quite a few Japanese animation studios were founded by well-respected producers, animators and directors:
** Several studios were founded by ex-Tatsunoko crew:
*** Creator/StudioPierrot was founded by a group of former Tatsunoko employees in 1979.
*** Ex-Tatsunoko Production and Kitty Film producer Tomoyuki Miyata founded Creator/JCStaff in 1986 after serving in Kitty Film's Mitaka Studio.
*** Mitsuhisa Ishikawa left Tatsunoko after the production of ''Anime/RedPhotonZillion'' to form Creator/ProductionIG in 1987 along with Takayuki Goto, retaining the staff that produced the series.
*** Kenji Horikawa left Creator/ProductionIG in 2000 for his native Toyama to follow a promise he made to his family. He would later go on to form his own animation studio, Creator/PAWorks, as there were no animation studios nearby at the time.
*** Anime producer Nagateru Kato left Tatsunoko Pro to serve as a producer for MOVIC before going on to form Creator/{{TNK}}.
*** Creator/KoichiMashimo began at Tatsunoko Productions in the 70s and went freelance by the late 80s. He eventually went on to establish his own studio, Creator/BeeTrain Production in 1997.
** Yutaka Fujioka formed Creator/TMSEntertainment after his previous company Tokyo Ningyo Cinema failed.
** Ex-TMS and Toei animators Creator/HayaoMiyazaki and Creator/IsaoTakahata teamed up to co-found Creator/StudioGhibli.
** Creator/{{GONZO}} was formed by Showji Murahama, Hiroshi Yamaguchi, Shinji Higuchi and Mahiro Maeda after they left Creator/StudioGainax in 1992. When GONZO went bankrupt in the early 2010s, Tomonori Shibata formed Creator/StudioGokumi, taking the staff of Studio No. 5 with him.
** Shortly after Osamu Nagai left GONZO in February 2009, he took his staff of animators with him to found Hoods Entertainment.
** After Masahiko Minami left Creator/{{Sunrise}} as an animation producer, he would later go on to form Creator/StudioBones.
** Mikihiro Iwata, also a producer for Sunrise, would later go on to found Creator/A1Pictures in 2005.
** Former Creator/MushiProductions animators Masao Maruyama, Osamu Dezaki, Rintaro and Yoshiaki Kawajiri formed Creator/{{Madhouse}} in October 1972. When Maruyama retired from Madhouse in 2011 at the age of 70, he went on to found Creator/{{MAPPA}}.
** After Jiyū Ōgi and Yoshiyuki Matsuzaki left Creator/{{AIC}}, they would later go on to found Creator/ProductionIMS in 2013. Unfortunately, Production IMS shut down in 2018 due to bankruptcy.
** Gaku Iwasa formed Creator/WhiteFox in 2007 after leaving Creator/OLMIncorporated.
** Hayato Kaneko served as an animation producer for the animation studio Frontline. He would later go on to found his own company, Creator/SilverLink, in 2007 after leaving Frontline.
** Studio Chizu was established by producer Yūichirō Saitō and director Creator/MamoruHosoda after leaving Madhouse in 2011.
** When Studio Ghibli temporarily halted production of their works following Creator/HayaoMiyazaki's temporary retirement, producer Yoshiaki Nishimura left the studio and formed Creator/StudioPonoc to produce ''Anime/MaryAndTheWitchsFlower''.
** Producer Yoko Hatta was a cel painter with Mushi Production. After marrying her husband, Hideaki in the late 70s the pair founded Creator/KyotoAnimation.
** Creator/KnackProductions was formed by ex-Mushi and Toei staff, including Seiichi Hayashi, Sadao Tsukioka, Sakuro Koyanagi, and Seiichi Nishino. In spite of the talent involved, Knack Productions became infamous for its rather poor quality production, most notably ''Anime/ChargemanKen''.
* In approximately 2001, the editorial board of [[Creator/SquareEnix Enix]]'s ''Shonen [=GanGan=]'' brand decided to move back to a more "orthodox" {{shonen}} direction, and shifted a large number of MultipleDemographicAppeal works--or even outright {{shojo}} series--to newer magazines such as ''Monthly Stencil'' or ''Monthly [=GFantasy=]''. This caused a rather large uprising from its editorial staff as well as affected mangaka; Ichijinsha (as well as the smaller Mag Garden) are formed by some of the disgruntled editors, who brought with them more than a few of their artists. This is why Ichijinsha, publisher of ''Comic ZERO-SUM'' and ''Magazine/YuriHime'', is more known for its female-oriented works.

!!Video Games
* ''VideoGame/SuperMarioFusionRevival'' is an odd case. [=JudgeSpear=] long ago started a game he called ''Super Mario Fusion: Mushroom Kingdom Hearts'', a fan game focused on Mario visiting other dimensions. The influence of other developers made it mutate into ''VideoGame/MushroomKingdomFusion'', a game that took MegaCrossover to the next level. At one point in development communication between [=JudgeSpear=] and other developers was strained, so the game mutated further in that direction without his consent. When he became active again, ''VideoGame/MushroomKingdomFusion'' was so different from his original idea that he decided to leave it be and essentially used this trope ''on himself''.
* While working at Creator/{{Atari}}, Jay Miner (having previously developed the [[UsefulNotes/{{Atari 2600}} 2600]] console and 800 computer) designed what would become the Amiga. Frustrated that Atari wouldn't produce it, he left, starting his own company, Hi-Toro, to build it. Hi-Toro went bankrupt, but Commodore bought them and the Amiga design, eventually manufacturing it themselves.
* A handful of Atari programmers during the [[CorruptCorporateExecutive Ray Kassar]] era were disgruntled that not only were they not getting credit for the games they created, but such information was treated as top secret. So they formed Creator/{{Activision}}, the world's first third-party gaming company, which upon creation gave credit to the programmer who created the game right on the game box and in television commercials.
* Creator/ElectronicArts was also founded for similar reasons not too long afterward. Now look at what they've become, although in hindsight, Activision is no different.
* The development studio Creator/TriAce, known for the ''VideoGame/StarOcean'' series, is named for the three employees who left Creator/TelenetJapan's Wolf Team studio to strike on their own. One of them was the main programmer of ''VideoGame/TalesOfPhantasia'', who was frustrated with the ExecutiveMeddling from [[Creator/BandaiNamco Namco]] that occurred with the game's development.
* A sad case is when most of the old-school developers of Creator/BlizzardEntertainment (the people responsible for ''VideoGame/{{Warcraft}}'' one and two, ''VideoGame/{{Diablo}}'' and ''VideoGame/StarCraft'') left to form their own game studio, made the Diablo-clone ''VideoGame/HellgateLondon'', and bankrupted.
* Creator/TelltaleGames is another example, founded by ex-Creator/{{LucasArts}} employees Kevin Bruner, Dan Connors and Troy Molander after [=LucasArts=] all but abandoned the AdventureGame genre.
* Like the Telltale Games example above, Tim Schafer and Ron Gilbert also left [=LucasArts=] at around the same time to form Creator/DoubleFine.
* Ditto for Petroglyph Studios, formed by former Creator/WestwoodStudio employees after EA shut down Westwood.
* And the same thing can be said of [[http://www.rawthrills.com Raw Thrills]], which was formed in 2001 by Creator/EugeneJarvis after Creator/MidwayGames shut down their arcade division the year prior.
* The Creator/{{Sony}} UsefulNotes/PlayStation began life as [[UsefulNotes/{{SNESCDROM}} a CD add-on]] for Creator/{{Nintendo}}'s [[UsefulNotes/SuperNintendoEntertainmentSystem Super NES]] console. However, when Nintendo backed out of their contract with Sony during development[[note]]because a buried clause would have given Sony perpetual rights to Nintendo's games[[/note]] and instead contracted with Philips for the add-on (which never materialized[[note]]but did spawn the infamous ''VideoGame/TheLegendOfZeldaCDiGames[[/note]]''), and dumped Sony in the most dickish way imaginable to Japanese businessmen (news of the change was withheld from Sony until the day of the CES, and then announced in front of an audience), Sony turned to Sega... only to be laughed at by the Sega execs, who claims that Sony knows nothing about the video games industry. This resulted in them turning the peripheral into a stand-alone console and entering the game market themselves, determined to teach Nintendo and Sega a lesson...which they did, displacing Nintendo's position at the top of the game industry with the UsefulNotes/PlayStation while contributing to the death of Sega's hardware business, and then retaining their stranglehold on the market with the UsefulNotes/PlayStation2, forcing Nintendo to [[TakeAThirdOption re-think gaming entirely]] in order to get back on top with the UsefulNotes/{{Wii}}. To be fair, however, Sony's hands aren't clean in this. While no one may ever know for sure, Sony had inserted a clause that would have resulted in Sony getting a very significant portion of the profits from all sales and complete control over licensing. At the time, Nintendo CEO Hiroshi Yamauchi did not see much point in such a peripheral and assumed that gamers would not respond well to loading times, and initially refused the deal. Sony assured him they would only publish everything BUT video games on the new media. Nintendo told them, "Do your CD-ROM thing." Sony, however, had been expanding from a mere electronics company into a conglomerate, having spun off an insurance company with Prudential in the late '70s, and in the span of the final two years of the '80s, signed deals to purchase both CBS Records and Columbia Pictures. Most tellingly perhaps, in its first example of this trope, Sony even formed Creator/SonyImagesoft, its first software development and publishing wing. Nintendo's CEO at the time, Hiroshi Yamauchi, was furious when he realized their true intentions and thought it was a great insult, and decided to fight fire with fire by humiliating Sony in public in return. It's easy to see this event as the cause of Sony's entry into the market, but Sony already had planned to manufacture their OWN SNES CD-ROM/cart units, titled Play Station, which left Nintendo out of the equation, meaning that Sony was just using Nintendo.
* Similar to the above, Atari passed up an opportunity to distribute the UsefulNotes/NintendoEntertainmentSystem in the US, leaving Nintendo to market and distribute the NES on its own. You know what happened next. Many video game fans think that was for the best; while the [=NES=] would have come to North America a couple of years earlier, it's likely that Atari's mismanagement would've simply [[UsefulNotes/TheGreatVideoGameCrashOf1983 dragged Nintendo down with them]], dooming the entire video game industry to a Japan-only niche.
* Creator/{{Treasure}} Co., Ltd. is a developer founded by the former employees of Creator/{{Konami}}. They are known for their action games with innovative design. They partner with large game developers and work with licensed titles.
* Creator/VinDiesel was so tired of [[TheTroubleWithLicensedGames crappy licensed games based on his movies]] that he formed his own company, Tigon. Their first release was ''[[VideoGame/EscapeFromButcherBay Chronicles Of Riddick: Escape From Butcher Bay]]'', which most consider ''better'' than the movie it's licensed from.
* Following Creator/KeijiInafune quitting Creator/{{Capcom}} and forming his own company ''Comcept'', Capcom's cancellation of ''Mega Man Universe'' and ''VideoGame/MegaManLegends 3'' (the latter of which Inafune was heavily invested in and had wanted to make for years), and Capcom making no more ''Franchise/MegaMan'' games aside from the universally reviled ''VideoGame/RockmanXOver'', Inafune started a crowdfunding campaign for a new game, ''VideoGame/MightyNo9'', a new Mega Man game in all but name. The Kickstarter for the game managed to raise its $900,000 goal in just over a day. The final sum raised? A whopping '''3.8 million US Dollars'''. Unfortunately, it didn't end positively despite getting off to a great start. They ended up being bought out by Creator/Level5.
* Creator/MonolithSoft was founded by staff from Creator/{{Square|Enix}}soft, notably the developers behind ''Videogame/{{Xenogears}}'' and ''Videogame/ChronoCross''. This was due to the staff wanting to do to a follow-up to the former, but the company was becoming heavily focused on ''Franchise/FinalFantasy'', in particular, their [[Anime/FinalFantasyTheSpiritsWithin new computer-generated film]]. Monolith Soft would be financed by [[Creator/BandaiNamcoEntertainment Namco]], developing the ''Videogame/{{Xenosaga}}'' series under them, until they would be bought by Creator/{{Nintendo}} just after the Wii launched.
* After being sold to Microsoft from Nintendo, many of Creator/{{Rare}}'s employees had left the company over a period of a few years. Most of them have since banded together to form a new company called Playtonic Games. Their crowdfunded project ''VideoGame/YookaLaylee'' managed to hit their funding goal of £175,000 (US$270,041) in 38 minutes of being launched.
* Yu Suzuki was KickedUpstairs after the failure of the ''VideoGame/{{Shenmue}}'' series (which did cost Sega a lot financially). He left the company to start Ys Net, and after years of silence, has come forward to crowdsource for the next installment in the ''Shenmue'' series, much to the joy of the fandom.
* Creator/HideoKojima spent much of 2015 living an absolute hell since Creator/{{Konami}} canceled ''VideoGame/SilentHills'', closed down his studio, Kojima Productions, removed his name from the cover of ''VideoGame/MetalGearSolidVThePhantomPain'', [[FromBadToWorse and even]] forbade him from accepting any awards the latter game won. As soon as his contract with Konami expired, he established his own independent game studio called...[[{{Irony}} Kojima Productions.]]
* Victor Ireland was the president of Creator/WorkingDesigns since he transformed it from an office software developer to a video game publishing company in 1990, four years after its founding. After Working Designs shut down in December 2005, Ireland formed Gaijinworks seven months later, with the rest of his staff joining him.
* The video game ''Jawbreaker'' was a case of this. It started out as a near-perfect port of ''VideoGame/PacMan'' for the UsefulNotes/Atari8BitComputers done by [[Creator/{{Sierra}} On-Line Systems]]. However once Creator/{{Atari}} caught wind of it, rather than do the decent thing and license the program, they attempted to bully the programmer into giving them the game. As a result, ''Jawbreaker'' was released as its own game.
* Creator/JerseyJackPinball was started when game distributor Jack Guarnieri noticed his customers wanted expensive pinball games with deep rules and lots of mechanical toys, but Creator/SternPinball was moving towards simpler, low-budget tables. Jack decided the only solution was to start his own company and make the types of games that his buyers wanted.
* It's been suggested that this trope was what inspired the inception of 2-D fighting game ''Beast's Fury'' by Evil Dog Productions; the leader of the development team, Ryhan Stevens, wanted the same fame and recognition (if not more) as ''VideoGame/{{Skullgirls}}'', which had enjoyed a very successful crowdfunding campaign. The game would later be canceled in 2016 following a [[TroubledProduction contentious production]] and online acrimony towards ''Skullgirls'' fans, which left the reputations of Stevens and Evil Dog tarnished.
* A successful example of this trope: Eric Barone, having just graduated from college (computer science) decided to start making a game for fun and to practice his programming, he was a big fan of ''Videogame/HarvestMoon'', but considered the series to had gone downhill after ''Back to Nature'' and was unable to find something he thought was a suitable substitute for PC. He started to develop a ''Harvest Moon'' clone under the moniker [=ConcernedApe=], but the project gradually grew in scope, and four years later, ''Videogame/StardewValley'' was born.
* Creator/{{Natsume}} were the people that translated Marvelous main franchise, Bokujō Monogatari, under the name ''VideoGame/HarvestMoon''. However, Marvelous dropped Natsume and went with Creator/XSEEDGames, a U.S.-based localizer and publisher of Japanese games that became a subsidiary of Marvelous a year earlier. However, since Natsume owns the rights to the Harvest Moon name, they decided to make their own and keep the series going. Bokujō Monogatari is now released under the name ''VideoGame/StoryOfSeasons''.
* With ''VideoGame/{{Doom}}'' being very friendly to modded content, this hilariously happened one time with the release of ''Doom: Rampage Edition''. A mod infamous for its... ''quality''. One reviewer said he could pull a better wad [[JustForFun/IThoughtItMeant (Doom mod files were called WADs)]] from out of his ass. Lo and behold, three weeks later said reviewer came out with a mod: A Better Wad Pulled From My Ass.
* In 2015, Creator/{{Tencent|Games}} acquired Riot Games and requested them to make a mobile port of their global smash hit, ''VideoGame/LeagueOfLegends''. [[ItWillNeverCatchOn Riot at the time declined]], considering ''League'' to be too sophisticated of a game to try and simplify for a smartphone's interface, which Tencent then responded with "very well, then we'll try making a mobile [[MultiplayerOnlineBattleArena MOBA]] ourselves." (thankfully for Tencent, two of their subsidiaries, [=TiMi=] and L&Q, actually believed in the potential on the get-go, unlike Riot.) The end result was ''VideoGame/HonorOfKings'' (adapted internationally as ''VideoGame/ArenaOfValor'')[[note]]Initially it was more of [[SerialNumbersFiledOff a direct knockoff]] of ''League'' called ''League of Kings'', [[{{Irony}} but after receiving enough complaints from Riot as being borderline plagiarism]], Tencent took additional time for significant {{retool}}ing to form its own identity[[/note]] (by [=TiMi=] after an intercompany encouraged rivalry with L&Q, to which they bounced back from defeat), which then became an enormous smash hit in its own right, becoming the most popular mobile property in their native China by the end of the decade. [[{{Irony}} Ironically]], its powerhouse success [[AndYouThoughtItWouldFail convinced Riot to reconsider their stance on mobile MOBAs]], leading to their mobile port of ''League'' being developed and released in late 2019 (Tencent would temporarily halt their plans of marketing ''Arena of Valor'' in western regions to allow Riot to make their announcements, so it seems there are no hard feelings in the matter).
* ''Franchise/FireEmblem'' creator Shouzou Kaga left Creator/IntelligentSystems shortly after the release of ''VideoGame/FireEmblemThracia776'' for still undisclosed reasons [[note]]Theories abounds: some says Kaga left over disagreements regarding the direction the games were going, others says he was actually fired over the rather mercurial development of ''[=Thracia776=]'' along with Kaga's alleged bullheaded refusal to modernize the series to appeal to modern audiences.[[/note]]. Kaga went and formed Tirnanog studios, eventually released ''VideoGame/TearRingSaga'' for the Playstation. The game turned to be such a [[SerialNumbersFiledOff blatant Fire Emblem ripoff]] that Nintendo took both Tirnanog and game publisher Enterbrain to court. Things were settled out of court and all those involve [[OldShame would rather not talk about it ever again]].

!!Other
* According to some of [[WordOfGod Charles M. Schulz's autobiographical books]], the reason why Franchise/{{Hello Kitty}} and [[Creator/{{Sanrio}} Sanrio characters]] came into existence was due to a [[CreativeDifferences disagreement]] [[ExecutiveMeddling he had with the company]]. Sanrio also grew tired of paying royalty fees to [[Creator/CharlesMSchulz Schulz]]. [[note]] Sanrio had merchandise rights for Snoopy back in the 60s and early 70s.[[/note]] As a result, the company decided to create its own characters. In later years, the company gained back the merchandise rights to the ComicStrip/{{Peanuts}} franchise in Japan.
* Literature/FactionParadox started out as characters in the Franchise/DoctorWhoExpandedUniverse, specifically the Literature/EighthDoctorAdventures. When someone else was allowed to write a novel that not only changed the Faction's whole character but also derailed his plans for portraying the Time War they were involved in, their creator decided to spin the Faction off into their own series with its own, separate mythos.
* After getting fired from Gamespot for undisclosed reasons (though the most popular is for giving a mediocre review to ''VideoGame/KaneAndLynch: Dead Men'' while the game was advertised on the site), Jeff Gerstmann went off to start the gaming news site Website/GiantBomb alongside other former Gamespot journalists. Ironically, they would end up becoming a sister site to Gamespot when Giant Bomb got purchased by then Gamespot's parent company, [=ViacomCBS=].
* Fred Rogers went into television precisely because he hated it so and thought there could be a better way of using it to educate young children -- thus was born ''Series/MisterRogersNeighborhood''. He especially took objection to the emphasis television put on violence (the first thing he ever saw on TV was [[PieInTheFace a pie fight]]) and advertising (which led to him quitting his job with Creator/{{NBC}} to work in public television instead).
** When Fred moved back to the U.S. from Canada to continue ''Series/MisterRogersNeighborhood'' for what was then called [=NET=], his understudy Ernie Coombs stayed in Canada and created his own show, ''Series/MrDressup''.
* [[UsefulNotes/EsperantoTheUniversalLanguage Esperanto]], along with any other constructed language.
** Ido, its most popular offshoot.
* Mary Seacole, a Jamaican nurse in the Crimean War, was rejected by Florence Nightingale for being black, so she started her own hospital on the front line of the British Hotel. She was ten times more involved than Florence and went to the front line herself. She died penniless, but she has been remembered by history, no matter if no one really remembers who she was outside of certain circles.
* Creator/KunihikoIkuhara directed the second to fourth season of the 90s version of ''Manga/SailorMoon''. But when Creator/ToeiAnimation didn't give him enough creative control for ''[=SuperS=]'' he [[Anime/RevolutionaryGirlUtena decided to create his own shoujo series]].
* When the Sony forums were hacked in 2011, the fanbases for their two biggest game show properties (''Series/WheelOfFortune'' and ''Series/{{Jeopardy}}'') migrated to fan forums and have been there ever since.
* After Jean Chalopin left Creator/DicEntertainment, he went on to found his own company, C&D[[note]]Standing for Créativité et Devéloppement", just as "D.i.C" had (originally) stood for "Diffusion, information, et Communication".[[/note]], which had produced its shows in a similar style.
* The hotel chain America's Best Value Inn was started in 1999, and most of its first properties at the time were recently rebranded from other chains (predominantly Best Western and unbranded properties). The same is true of rival Magnuson Hotels.
* In 1981, directer Larry Cohen was removed from the director's chair of a remake of ''[[Literature/MikeHammer I, the Jury]]'', just before filming began.[[note]]Though he still got screenplay credit[[/note]]. Since he already had shooting space reserved, he decided to use it to shoot his own movie. That movie turned out to be ''Film/QTheWingedSerpent''.
* Adam Pacitti, Adam Blampied, Jack King, Ross Tweddell, and Sam Driver resigned from [=WhatCulture=] in fall 2017. By November, four of them [[note]]Blampied's contract was terminated after he confessed to soliciting female fans online[[/note]]had formed a new wrestling-themed Website/YouTube channel, WebVideo/{{Cultaholic}}.
* After making his internet fortune, Elon Musk spent quite a bit of time attempting to purchase space rockets from the Russian government to support a philanthropic pro-Mars-exploration venture he had his eye on. After several failed attempts, he decided he'd just make the rockets on his own and funded [=SpaceX=]
** Likewise, Musk spent time keeping up on the latest efforts in the automotive industry towards the wide-scale development and production of electric cars, and repeatedly urged the company AC Propulsion to pursue broader development of its tzero prototype - something the company utterly refused to do. Shortly thereafter, Musk would co-found Tesla Motors, which became Tesla Inc. once it expanded into solar energy and large-capacity batteries.
* In Malaysia, Chatime attempted to wrest control of the stores from the franchisee of the time in 2017 due to the usage of ingredients that are from suppliers instead of from Chatime themselves, as well as the franchisee not paying the royalties in licensing for the rights to use the name. The franchisee's response? Immediately cutting ties and rebranding to Tealive. Although Chatime did try taking the franchisee to court (they lost the case in Malaysia, although they tried again in Singapore and the battle is ongoing). Chatime opened their own stores in Malaysia a year later in 2018, also making this a case of CreateYourOwnVillain.
* Some of the biggest names in roller coaster manufacturing today are spinoffs from other companies.
** Bolliger & Mabillard have designed over 117 roller coasters around the world. The company's founders, Walter Bolliger and Claude Mabillard, originally began as engineers at Giovanola, a contractor to roller coaster manufacturer Intamin. During their time at Giovanola, they helped design the company's first stand-up roller coaster, Shockwave at Six Flags Magic Mountain.[[note]]Later the defunct Batman The Escape at the defunct Six Flags Astroworld[[/note]] They also worked on other projects, such as Z-Force at Six Flags Great America.[[note]]Which was the only ever "space dive coaster" built. It ran at Six Flags Great America until 1987, then as part of a ride rotation program Six Flags implemented at the time, rotated to Six Flags over Georgia for three years, then ended up at Six Flags Magic Mountain from 1993 until its demolition in 2006[[/note]] In 1987, a change of management at Giovanola led Bolliger and Mabillard to leave and start their own firm, originally comprised of just themselves and two draftsmen.[[note]]Giovanola continued to use the two engineers' box track design, which is seen on their two hypercoasters, Goliath at Six Flags Magic Mountain and Titan at Six Flags Over Texas[[/note]] This was all they were made of when they built their first roller coaster, Iron Wolf at Six Flags Great America, in 1990.[[note]]Now converted into a floorless coaster called Firebird at Six Flags America[[/note]] In 1992, they built their first inverted coaster, Batman: The Ride at Six Flags Great America, and from there on, the rest is history.
** Great Coasters International, one of the leading names in wooden roller coasters in the 21st century, was founded by Mike Boodley, a designer at the 1990s wooden roller coaster construction firm of Custom Coasters International.
*** Custom Coasters International themselves were more or less the successors to the Dinn Corporation, on account of their founders being the two children of Dinn Corp.'s founder Charles Dinn. When CCI went bankrupt and liquidated in 2002, most of its designers stuck together to constitute a new firm called The Gravity Group, best known for their construction of The Voyage at Holiday World (the world's second longest wooden roller coaster behind only The Beast at Kings Island).
* Sometime after Creator/{{Nelvana}} co-founder Michael Hirsh left the company, he bought the assets of the crumbling [=CINAR=] to create his own company, Creator/CookieJarEntertainment.
* In 2015, Joel Hodgson launched a successful Website/{{Kickstarter}} campaign to resurrect ''Series/MysteryScienceTheater3000'' and sold the rights to air the new seasons on Creator/{{Netflix}}. When Netflix declined to make a third season and the UsefulNotes/COVID19Pandemic hit, Joel decided to go back to Kickstarter to not only resurrect the series again, but make ''his own'' streaming service, inspired by the change in filmmaking the pandemic pushed.
* UsefulNotes/NikitaKhrushchev [[https://www.rbth.com/history/327869-soviet-disneyland-failed proposed building]] the Soviet Union's very own Ride/{{Disneyland}} following a much-publicized incident where the Soviet Premier was barred from entering ostensibly due to security concerns. Wonderland, as it was called, was conceived as "the entire Soviet Union in miniature" instead of focusing on a fantasy world sprinkled with various fictional characters as is with Disneyland's, affording Soviet children the chance to appreciate the country's diversity. While the Wonderland idea never came to fruition due to Khrushchev's removal from power in 1964, the Moscow-based [[https://dreamisland.ru/ Dream Island]] [[https://www.nytimes.com/2020/02/29/business/russia-dream-island.html picked up where Khrushchev's project left off]], and offered its own takes on Disney's attractions, even adapting Creator/HansChristianAndersen[='=]s ''Literature/TheSnowQueen'' story in an effort to evoke Elsa from ''[[WesternAnimation/Frozen2013 Frozen]]''.
* As Paul Wernick worked on ''Series/BigBrother 2'', he and friend Rhett Rheese decided to do their own take of reality television, resulting in the satirical ''Series/TheJoeSchmoShow''.
* When Creator/JeremyClarkson got fired from ''Series/TopGear'', co-hosts Creator/JamesMay and Creator/RichardHammond both quit the show in solidarity. The three of them then went on to create ''Series/TheGrandTour''.
* After William J. Abbott stepped down as CEO of Crown Media, Hallmark's television channels holding unit, he bought Great American Country from Discovery Inc., formed [=GAC=] Media and re-launched the network as [=GAC=] Family, positioning it as a competitor to the Creator/HallmarkChannel by hiring away a number of actors associated with Hallmark programming for the purposes of starring in [=GAC=] Family's original content and picking up the rights to several shows that Hallmark had cancelled.
* Jared Mauch, a rural Michigan resident who was sick of not being able to get good broadband service from AT&T or Comcast, [[https://arstechnica.com/tech-policy/2022/08/man-who-built-isp-instead-of-paying-comcast-50k-expands-to-hundreds-of-homes/?comments=1 built a fiber ISP]], albeit with the help of some government assistance and an angel investor or two. He subsequently expanded his [=ISP=] service's network across his area using government grants, and the broadband community generally applauded his attempts to take matters in his own hands.

* This can occur sometimes in {{Speedrun}}ing communities when new glitches or techniques are discovered that radically alter how the speedrun of a game plays. Either the pre-existing categories accept the new technique, which prompts those opposed to it to create a new category that bans it to preserve the old style of play, or the pre-existing categories ban the new technique, which results in new categories that allow it in order to explore what new kinds of metagame develops around the technique. The result of this is that the leaderboards for some games can several tabs on sites like speedrun.com.

* ''Series/YoungSheldon'': In "Legalese and a Whole Hoo-Ha', tired of having Hagemeyer, Linkletter and his parents fighting over the contract for the database project, Sheldon decides to just work on it alone using private funding.

* In, ''LightNovel/{{Haganai}}'', Yozora starts the Neighbors Club as a club where people without friends could learn to make friends. Unfortunately, because LonersAreFreaks, the only people they get are other weirdos, and they more or less end up LonelyTogether.
* This is Haruhi's motivation for starting the SOS Brigade in ''LightNovel/HaruhiSuzumiya'' after she joins ''every single club'' at the school and quits after she gets bored.
** Played very straight by being the direct cause of the plot in ''Boredom''.

* ''WebAnimation/OverTheHills'': The plot is kicked off by the railroad that serves the Penwyth Valley and the towns in it closing down, and the people suffering through a winter that closed the roads. So, they all banded together to start a heritage railway group to run trains on the rails themselves.

Nintendo's CEO at the time, Hiroshi Yamauchi, was furious when he realized their true intentions and thought it was a great insult, and decided to fight fire with fire by humiliating Sony in public in return. It's easy to see this event as the cause of Sony's entry into the market, but Sony already had planned to manufacture their OWN SNES CD-ROM/cart units, titled Play Station, which left Nintendo out of the equation, meaning that Sony was just using Nintendo.

* ''Film/RevengeOfTheNerds'' centers around the titular {{nerd}}s creating their own fraternity chapter after being rejected by all the existing ones. Of course, being nerds, the only one that will even give them a chance is the historically-black Lambda Lambda Lambda, due to a loophole which requires the frat to give them a trial period to start their own chapter. This does [[ScaryBlackMan come in handy]] [[BigDamnHeroes later on]] in the movie.

* Also, [[TheWikiRule Wikis]]. Many are started because they have focused subject matter, but many others are founded because Wiki/{{Wikipedia}}'s standards of notability and citation somehow exclude them, or they think there's something biased about it. For instance, Conservapedia was created by a group who decried Wikipedia's "evidence" and "objectivity", and made their own online encyclopedia with their ''own'' bias. [[Wiki/TVTropes This very wiki]] specializes in covering the tropes of popular culture. Since Wikia allows anyone that wants to start a Wiki to do so, this happens quite often with those who don't like the guidelines, procedures, etc., etc. of a particular wiki. It often doesn't end well, since most of these people are neither suited to be admins nor have the ability to gather followers to their new wiki. One of the most prominent examples (and far more successful than most) is the ''Franchise/StarWars'' fandom's [[PunBasedTitle Wookieepedia]], which came about when Wikipedia purged a great many ''Star Wars'' articles as "non-notable". Copies of the purged articles were part of the core of Wookieepedia in its early days. Now Wookieepedia is the 5th-largest Wiki in existence.

* [[http://scp-int.wikidot.com/scp-1054-fr-j SCP-1054-FR-J]] was written as a satire of certain events surrounding the ''Wiki/SCPFoundation'', in which a scientist leaves the Foundation and starts his own competing organisation, the RPD Command. Then another scientist bring up grievances about how he's running the Command, while at the same time similar events happen at the Foundation, causing both resulting organisations to split again, and so on.
