* ''VideoGame/BattleGaregga'' is easily one of the most infamous {{shmup}}s within the shmup community, thanks mainly due to its [[DynamicDifficulty rank]] system that cranks up the game difficulty as the player collects items, fires their weapons, and simply survives, and if not managed ''deliberately'' (through [[ViolationOfCommonSense abstaining from picking up power-up items and intentionally dying]]), the rank can spike to a point where the game goes from NintendoHard to nigh-UnwinnableByDesign. The RealIsBrown aesthetic that was unique at its time, the more iconic boss designs like that of [[ClimaxBoss Black Heart]], and the game being Creator/ManabuNamiki's debut as a game music composer also further establish ''Battle Garegga'' as one of the most iconic shmups, and nearly everyone in the shmup community has a strong opinion on it (whether good or bad). Outside of said community, however, almost nobody has even heard of it. While this can be attributed to the game being largely inaccessible to the Western world due to its arcade release being limited outside of Japan and its only port for almost 20 years being a UsefulNotes/SegaSaturn port that, in addition to being on a system that sold poorly, was released in Japan only, even after the UsefulNotes/PlayStation4 and UsefulNotes/XboxOne ports made it to the West it's still not something that is going to catch the average gamer's eye, not helped by its high price for a shmup at 34.99 USD.

* Radio/JohnPeel was one of the most influential trend-setters in the British music industry, and famed for his willingness to play just about ''anything'' if he liked the sound of it, [[TheLastDJ regardless of what the higher-ups might think of it]]. A number of artists who would go on to be big names in the punk, metal and alternative scenes got their big break by mailing a demo-tape to his PO box at the BBC. Outside the UK, however, he's almost unknown except, outside of a few people who might have heard his show on the BBC World Service, and various ''Peel Sessions'' albums by artists who appeared on his show being released.

%%* {{Pinball}} has been hit with this extremely hard. Despite being a major part of American culture for nearly a century, most people would be hard-pressed to name more than one or two pinball manufacturers or [[PinballCreators designers]], if at all, and as far as the games themselves, you won't hear much beyond ''Pinball/TheAddamsFamily'', ''Pinball/Terminator2JudgmentDay'', or ''Pinball/JurassicParkDataEast''. The history of the field is an even bigger mystery to most -- folks who recall the controversy behind [[UsefulNotes/AlGore Tipper Gore]] and the Parental Advisory labels, ''VideoGame/{{Mortal Kombat|1}}'' and the [[UsefulNotes/EntertainmentSoftwareRatingsBoard ESRB,]] or [[UsefulNotes/TheComicsCode Frederic Wertham and "Seduction of the Innocent"]] will seldom have any knowledge of the nation's ''thirty-year ban'' against pinball.

* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'': Popular to the point of ubiquity on the internet, but still relatively obscure to a lot of people who don't go online much, or don't get the cable channel the show is broadcast on; other media are [[FirstInstallmentWins more likely to reference or parody]] Franchise/MyLittlePony in general rather than ''Friendship Is Magic'' specifically. If anything, it's likely to get most of its exposure from mainstream media poking fun at its [[PeripheryDemographic adult fanbase]], i.e. "bronies". This may lead to the impression that most of the fanbase is just weird.

* ''Franchise/{{Pokemon}}'' is a juggernaut CashCowFranchise that has been a best-seller for over twenty years, but people born after the mid-1980s often don't know of it. When ''VideoGame/PokemonGo'' became big with the mobile market, older adults and former fans who had "outgrown" the franchise were often confused that the series was still ongoing (which led to [[CowboyBebopAtHisComputer articles and newsites]] citing ''Go'' as a reboot of a 1990s classic).

%%* Female and black superheroes are a big victim of this trope. Whenever a new (or newly popular) black or female character is mentioned in a news story (especially when the entire point of the story is that most superheroes are white men, such as when a paper interviews a local artist who's just getting into the industry, almost always involving a quote along the lines of "reading comics as a kid, I always wondered why there weren't more characters who looked like me") the article will act as if there are, at most, three black superheroes (the average non-comic-reader ''might'' recognise Storm, ComicBook/{{Luke Cage|HeroForHire}} and ComicBook/BlackPanther, and [[Franchise/GreenLantern John Stewart]] if they [[WesternAnimation/JusticeLeague grew up in the nineties]]) and no superheroines except Wonder Woman. It's the same with gay and lesbian characters, except worse, because trying to discuss gay or lesbian superheroes often seems to attract homophobic trolls, plus there's still the assumption that only kids read comic books. Anytime an article in mainstream media talks about a gay or lesbian superhero, you can expect to see a shitload of comments about the "gay agenda" or "gays forcing acceptance down children's throats"...

%%* The MagicalGirl genre is one of the longest-standing and most profitable genres of anime and manga. Yet, few have much of an international reach outside of the original ''Anime/SailorMoon'' anime. The few that are internationally dubbed either fall into the GirlShowGhetto, are ScrewedByTheMerchandise, or are derided as niche ripoffs of ''Sailor Moon''. Even works with strong internet fandoms, such as the DarkerAndEdgier ''Franchise/LyricalNanoha'' and MagicalGirlGenreDeconstruction pioneer ''Franchise/PuellaMagiMadokaMagica'', haven't reached the mainstream. In Japan, ''Franchise/PrettyCure'' is a CashCowFranchise but it suffers strongly from NoExportForYou.

* ''Manga/SazaeSan' is an incredibly popular anime and manga franchise in its native Japan. Airings of ''Sazae-san'' on Sunday evening regularly have viewership numbering over a tenth of the Japanese population. However, it has never been released outside of its country nor has it been dubbed in any other language besides Japanese.

* There are two giants in the Japanese VirtualYouTuber scene: WebAnimation/{{Nijisanji}} and WebAnimation/{{hololive}}. However, international fans heavily gravitated towards hololive, leaving Nijisanji as a non-entity outside of its home country; this was cemented by hololive being the first to introduce a branch of Vtubers aimed at English-speaking fans that quickly exploded in popularity. For perspective, hololive's EN "Vsinger" [=IRyS=], with no content except a single tweet and the promise of a debut five days later, accrued more Twitter and [=YouTube=] followers than Nijisanji EN's fastest-growing talent at the time (Elira Pendora) accrued in a full month of streaming.

%%* A lot of Internet culture and {{meme|ticMutation}}s cause this. Anything that becomes popular on the Internet tends to stay in that particular sector of the Internet and completely unknown to those who don't use the Internet much or stay in a few social circles. {{Meme|ticMutation}}s are an especially visible example: Familiarity with very popular ones like Longcat or Trollface is a good Internet-savviness litmus test. {{Periphery Demographic}}s are another example; ''Franchise/{{Pokemon}}'' is still seen as weird for adults to enjoy, for instance, among casual Internet users. Because things that become popular on the Internet rarely make much headway offline, spending large amounts of time on the Internet can cause a pretty skewed idea of general trends. There are exceptions though, most notably teenage girl phenomena that lead towards mainstream commercial success, like Music/JustinBieber, or concepts that get popularized in mainstream media such as the [=YouTube=] memetic videos referenced in the ''WesternAnimation/SouthPark'' episode "Canada on Strike." Whether or not an Internet meme has been featured on mainstream media is generally considered a good indicator of whether or not that meme is now DeaderThanDisco.

%%* Speaking of the assumption that comic books are for kids, whenever a comic that is specifically ''not'' kid-friendly gets adapted into a movie, such as ''ComicBook/TheCrow'', ''ComicBook/{{Watchmen}}'', or ''ComicBook/{{Deadpool}}'', you're definitely going to hear stories of [[WhatDoYouMeanItsNotForKids unsuspecting parents bringing their kids to see it (despite the R-rating!) and then being shocked and appalled when an R-rated movie based on comics meant for adults is filled with graphic violence and sex]]. In fact, the creators of ''Deadpool'' outright predicted this and warned those unknowing parents "don't bring the kids" right in the trailers - not that this kept them from doing it anyway, of course. Even reviewers get in on this at times. One reviewer of ''Watchmen'' spent most of the review lamenting that we were now marketing extreme violence and adult content to children. When tons of readers commented that the movie and comic both were meant for adults, the reviewer stood by her words, stating that the existence of ''Watchmen'' action figures proved this movie was meant for children. Evidently, she had no clue that nerd culture includes grown men and women collecting action figures and that there are ''many'' lines of action figures marketed exclusively to adults.

%%* You probably know the Franchise/CthulhuMythos. You probably also know who Creator/HPLovecraft is. But do you know the names of Jim Turner, Creator/RobertBloch,[[note]]At least outside of writing the novel ''Film/{{Psycho}}'' was based on[[/note]] or Robert M. Price? No, Lovecraft didn't write ''all'' the Mythos. It's actually sort of like Franchise/StarWarsExpandedUniverse. Moreover, could you name any of the actual ''works'' of the Mythos? Probably ''Call of Cthulhu'' or if you're really in the know, ''At the Mountains of Madness'' may ring a bell. Same goes for any deities other than Cthulhu like Yog-Sothoth, Azazoth, or Nyarlathotep.
** Although the Mythos [[GermansLoveDavidHasselhoff are quite popular in places]] like France, Spain and Latin America in general.

* ''VideoGame/ClubPenguin'' was a casual {{Massively Multiplayer Online Game}}s that was especially popular amongst [[TurnOfTheMillennium 2000s]] children, but it rarely gets mentioned outside of the fanbase due to being a "kid-only" game that older gamers and reviewers weren't interested in, contrasted to more "adult" and well-known [=MMOs=] like ''VideoGame/WorldOfWarcraft''.

* InUniverse in ''ComicStrip/{{Dilbert}}'' when a schoolboy sarcastically comments on the fact that Dilbert considers it a shocking failure of public education that the boy can't name the highest waterfall in Africa, but Dilbert himself doesn't know who Music/MCHammer is and dismisses it as worthless trivia.

* Manga/OnePiece is exceptionally well known in its country of origin, but outside of Japan it the manga and anime were hampered by an incredibly poor English dub from 4Kids that fundamentally changed large swaths of the dialogue and edited scenes to make it more kid friendly. Despite this, a cult following found itself watching the subbed version of the original Japanese and people eventually found the English dub from Funimation that keeps most of the dialogue intact without removing any scenes. Bringing up scenes to someone who hasn't kept up to it, or pointing out to them how there is over 900 episodes of the anime can catch someone entirely off guard, and even if they ''want'' to join the series at this point, they have a lot of catching up to do.
