** After 10,000 cards were created in Japan, the card [[https://yugioh.fandom.com/wiki/Ten_Thousand_Dragon Ten Thousand Dragon]] was released.
** The 25th anniversary of the franchise was commemorated by introducing the Quarter Century Secret Rare rarity to booster sets released in 2023. The first six booster packs in the game's TCG print, as well as the first Legendary Collection box, were also re-released for the TCG with the addition of a 25th Anniversary seal on the packaging and the new card rarity.
** Also for the 25th anniversary, a video called [[https://www.youtube.com/watch?v=LSs4mBRy7nk Yu-Gi-Oh! Card Game the Chronicles]] was released, a series of clips set in the world of the cards.

* ''Fanfic/OnceUponAStudioVersionTwoPointOh'': This extended version of Creator/{{Disney}}'s [[WesternAnimation/OnceUponAStudio centenary short]] takes the occasion even more seriously, and shows the pressure of said anniversary to be the ''real'' reason why Goofy's attempt at the photo ends in failure, as the anxiety of the centennial simply becomes too much for many of the characters.
** In this particular case, WesternAnimation/{{Cinderella}}, [[WesternAnimation/{{Tangled}} Rapunzel]] and their respective princes take charge of the situation; Raps starts up a new and even more epic rendition of [[WesternAnimation/{{Pinocchio}} "When You Wish Upon a Star"]] on her guitar, and Cinderella sings the first two lines "When you wish upon a star/Makes no difference who you are", before handing over to [[WesternAnimation/BeautyAndTheBeast Belle and the Beast]]. The song steadily gains momentum as more and more characters join in, with others still helping Goofy undo his earlier mistake. This even includes a moment with [[WesternAnimation/TheLittleMermaid Ariel and Eric]], Rapunzel and Eugene and [[WesternAnimation/{{Aladdin}} Aladdin and Jasmine]] joining hands to sing the start of the final verse, followed by a surprise duet from [[WesternAnimation/{{Tarzan}} Tarzan and Jane]], before Cinderella and the Prince gently finish it off. Mickey and Cinderella then eagerly invite everyone gathered to join in for the final verse, and Cinderella [[BreakingTheFourthWall even extends this to the audience]]. Everyone then proudly sings the final verse together as a unified whole, [[MusicalNod before Cinderella and the Prince gently sing the first line of "A Dream Is a Wish Your Heart Makes" to the audience, followed soon after by Rapunzel and Eugene singing the opening to the chorus of "I See The Light" and Aladdin and Jasmine doing the same for "A Whole New World"]], before all the characters triumphantly sing the final line "Your dreams come true!", as Tinker Bell finally creates the photo.
** This final group photo is, if anything, even more spectacular than that of the existing OUAS, as it now features Yo-Yo Flamingo and the Spring Sprite from WesternAnimation/Fantasia2000 on the roof of the animation building, along with [[WesternAnimation/{{Moana}} Moana's father, Chief Tui]], standing proudly between her and Cinderella, and even [[GhostReunionEnding the spirit]] of [[WesternAnimation/TheLionKing1994 Mufasa]] watching happily from above.

* There is [[https://www.fimfiction.net/group/213885/the-not-so-cynical-creators-guild/thread/446327/yesterday-was-the-second-anniversary-of-this-group-being-made a thread]] and a [[https://www.fimfiction.net/story/476563/invasion-of-the-livid-bread story]] commemorating the second anniversary of Fanfic/TheNotSoCynicalCreatorsGuild group on Website/FimfictionDotNet.

* To celebrate the 25th anniversary of Wrestling/MikeQuackenbush's in-ring debut, he has released matches that were personally special to him to Wrestling/{{CHIKARA}}'s Website/YouTube channel that had never been released in that medium before.

*** Toys: the ''Generations'' toyline features characters from non-G1 continuities (such as [[WesternAnimation/BeastWars Rattrap, Waspinator]], [[WesternAnimation/BeastMachines Tankor]], ''[[Anime/TransformersArmada Armada]]'' Starscream, and ''[[VideoGame/TransformersFallOfCybertron Fall of Cybertron]]'' Skywarp) who are represented in the [=IDW=] continuity (with their Hasbro figures including reprints of ''Dark Cybertron'' chapters). Hasbro debuted Masterpiece Soundwave to open the ''Thrilling 30'' toyline, along with Acid Storm (an MP-11 Starscream redeco), and is reissuing MP-10 Optimus Prime (in a special "Year of the Horse" deco) and Grimlock, and debuting Prowl. Takara issued MP [[Anime/TransformersHeadmasters Soundblaster]] with Ratbat, and will be issuing MP versions of Wheeljack, Bumblebee (with [[WesternAnimation/TransformersTheMovie Spike in his exosuit]]), Ultra Magnus, and [[Anime/TransformersVictory Star Saber]].
** The third part of the ''[[WesternAnimation/TransformersWarForCybertronTrilogy War for Cybertron Trilogy]]'', ''Kingdom'' (2021), commemorates the 25th Anniversary of ''WesternAnimation/BeastWars'' and as such features updated figures for almost the entire ''Beast Wars'' Season 1 cast, some of which had not received new figures in years. The line also commemorates the 35th Anniversary of ''WesternAnimation/TransformersTheMovie'' and features figures of Rodimus Prime, Galvatron, and Cyclonus. The rest of the movie cast also got their own dedicated subline in the ''Toys/TransformersStudioSeries'' line, ''Studio Series 86''.

*** The seventh film in the ''Film/TransformersFilmSeries'' and the second in the rebooted Travis Knight continuity after ''Film/{{Bumblebee}}'', ''Film/TransformersRiseOfTheBeasts'' was released on June 2023. On a toy-related note, the 100th figure in the ''Toys/TransformersStudioSeries'' line is Bumblebee's Offroad Camaro form from the movie (a nod to the first figure in the line being his 1977 Camaro form from the [[Film/{{Transformers}} first movie]]).

* ''Fanfic/OnceUponAStudioVersionTwoPointOh'': This extended version of Creator/{{Disney}}'s [[WesternAnimation/OnceUponAStudio centennial short]] takes the occasion even more seriously, and shows the pressure of said anniversary to be the ''real'' reason why Goofy's attempt at the photo ends in failure, as the anxiety of the centennial simply becomes too much for many of the characters.

** MLB would celebrate a more legitimate anniversary in 1969, marking the centennial anniversary of the first acknowledged all-professional baseball team, the Cincinnati Red Stockings (a separate franchise more closely linked with the Atlanta Braves than the modern Reds). MLB celebrated with a new patch featuring a brand-new logo that would be adapted to represent MLB going forward. They also celebrated the 125th anniversary in 1994, but the season-ending players' strike caused that to end on a sour note.

** Linkara celebrates the anniversary of his text reviews by reviewing issues of ''ComicBook/{{Youngblood}}'', and celebrates the anniversary of his video reviews by reviewing story arcs from ''ComicBook/TheCloneSaga''.

** He celebrated the 20th anniversary by releasing the back-to-the-roots-but-still-kind-of-90s sequel album ''Oxygène 7-13'' — about half a year late, but still. When asked back then which ''Music/{{Oxygene}}'' is his favorite, he jokingly replied it's [[LampshadeHanging the third one he's going to release in another 20 years]]. After the new album came Jarre's first indoors tour, the ''Oxygène Arena Tour'', during which neither of the two ''Oxygènes'' were played in full.

** He also celebrated the 30th anniversary. First he largely re-recorded the original ''Music/{{Oxygene}}'' at his studio. Then he took his three live co-keyboardists and his entire rig of about five dozen mostly vintage synths to the Belgian Alfacam Studios to re-record ''Oxygène'' yet again, this time not overdubbed but played live by these four musicians while being filmed and expanded by three ''Variations''. The outcome was titled ''Oxygène – Live in Your Living Room''. Next, he took ''this'' concept onto a live stage at Théâtre Marigny where he played ten concerts in a row. And then an actual tour followed with still the same concept. By then, Jarre was one and a half years late, and the last concerts of that tour were more than two years late, but the French consider being in time bad manners. All in all, Jarre celebrated the 30th anniversary of ''Oxygène'' by remaking the entire album 47 times over.

* Almost every ''WebVideo/ScottTheWoz'' season ends after 50 episodes, so naturally each SeasonFinale also doubles as a milestone celebration for Scott. The only exception so far is "You're Not An RPG Guy" which ended the season at Episode 195 instead.

** Subverted with his 300th episode. He (cliplessly) reviewed ''Film/TheForceAwakens'' with Creator/BradJones, but it was pretty lowkey. Mentioned because his ''299''th episode, ''Film/ChristmasWithTheKranks'', was a ContinuityPorn WhamEpisode.

* ''Literature/TheHungerGames'': The Quarter Quells are an InUniverse example. Every twenty-five years, a one-off twist is introduced to remind the people living in the districts of why the titular Games exist and of the Capitol's continuing power over them, with the nature of the Quell being announced by Panem's president months in advance. Hundreds of these Quells were planned, but only three actually took place and only the first two were played out to the end. The third Quarter Quell takes place during the events of ''Catching Fire'', but the Games are cut short with six tributes still alive.

** Averted with ''Music/{{Dangerous}}''; a 25th anniversary reissue was announced for 2016, to feature new songs, demos and remixes, but never materialized.

* Major League UsefulNotes/{{Baseball}} celebrated the game's centennial in 1939, by having all sixteen teams wear a commemorative patch, one of the first such anniversary patches in sports. This was all based on the widespread lie that Abner Doubleday had invented the game in Cooperstown, NY in 1839. The National Baseball Hall of Fame and Museum had been established in Cooperstown in 1936.
** MLB would celebrate a more legitimate anniversary in 1969, marking the centennial anniversary of the first acknowledged all-professional baseball team, the Cincinnati Red Stockings (a separate franchise from the modern Reds). MLB celebrated with a new patch featuring a brand-new logo that would be adapted to represent MLB going forward. They also celebrated the 125th anniversary in 1994, but the season-ending players' strike caused that to end on a sour note.

* The most confusing slate of team anniversaries possibly belongs to MLB's Houston Astros. Their first season was in 1962 as the Houston Colt .45s, but legal action from Colt's Manufacturing Company forced them to change their name to the Astros in 1965. The Astros had celebrated their 25th season in 1986, their 35th season in 1996, their 40th season in 2001, and their 45th season in 2006. But then they decided to celebrate the 45th ''anniversary'' of becoming the Astros in 2010. This was followed by their 50th anniversary celebration in 2012 (their 51st ''season''), and then the 50th anniversary of becoming the Astros in 2015.

* The Webcomic/{{Walkyverse}} tends to have low-key acknowledgements of its various anniversaries. Often, these have characters reach significant milestones in their lives, and acknowledge the universe's history.

* ''[[LetsPlay/TacoMan Taco-Man Plays a Video Game]]'':

** In October 2021, to mark ''Music/TattooYou'''s 40th anniversary, it was re-released with 9 unreleased tracks and a live album recorded at Wembley Stadium in 1982, also serving as a tribute to drummer Charlie Watts, who passed away in August 2021 at age 80.

* There is [[https://www.fimfiction.net/group/213885/the-not-so-cynical-creators-guild/thread/446327/yesterday-was-the-second-anniversary-of-this-group-being-made a thread]] and a [[https://www.fimfiction.net/story/476563/invasion-of-the-livid-bread story]] commemorating the second anniversary of WebOriginal/TheNotSoCynicalCreatorsGuild group on Website/FimfictionDotNet.

* UsefulNotes/FormulaOne celebrated it's 70th annivesary in 2020 with a TitleSequence filled with highlights from the sports history, and (primarly due to the COVID-19 pandemic), held a one-off race at Silverstone called the 70th Anniversary Grand Prix, a fitting name given that the race track hosted the first ever F1 World Championship race in 1950.
