Pop-Culture Isolation is basically a case of pop-culture myopia of sorts. Where celebrity, music genres, media or events that are huge and significant in one subculture or ethnic group, but elsewhere nobody knows it exists or is indifferent to it altogether. We're not talking about separate countries here, but ''within'' the same country or region. A lot of this is especially prevalent in entertainment, especially music. Radio is probably the main cause of this as radio is very isolated in terms of programming and format. Though some just see all of this as another form of segregation.

Let's face it, there are cultural barriers, and people thrive in their own microcosm. Another likely reason for this is because mainstream media is so homogenized and is prone to favoring monochrome pop culture that other cultures [[StartMyOwn start their own]] pop-culture media outlets. That fuels this trope even further for better or for worse. This isolation of pop culture can lead to such ignorance as CowboyBebopAtHisComputer. It's even possible for this trope to happen within the same culture. This, in turn, resulted in a pop cultural BrokenBase or FandomRivalry. HipHop is a good example of this (see Hip-Hop's BrokenBase entry). This trope possibly could lead to MonochromeCasting.

Expecting Pop-Culture Isolation not to be an issue is a sure way to incur PopCulturalOsmosisFailure. Can also result in people outside the subculture experiencing InformedRealLifeFame.

For [[ItsPopularNowItSucks some people with a certain ideology]], however, Pop Cultural Isolation may be seen as a ''good'' thing.

Contrast SmallReferencePools, and PopCulturalOsmosis. May lead to GermansLoveDavidHasselhoff or AmericansHateTingle. Could also overlap with CriticalDissonance. This trope along with PublicMediumIgnorance goes together like peanut butter & jelly. This often is the cause of MinorityShowGhetto. Compare with FanMyopia, which is when the fans of a particular form of pop culture believe it to be far more well-known amongst the general public than it actually is.

By the way, did you know there are people and places out there who discuss and list the tools of storytelling but have almost no knowledge of wiki editing or TVTropes? It's very true. Do you know about them? Probably not.


[[folder:Anime & Manga]]
* A good deal of {{Anime}} and {{Manga}}, outside ''Franchise/SailorMoon'', ''Anime/SpeedRacer'' and the like, [[SlidingScaleOfAnimeObscurity is not well known outside the fanbase]]. Just see the TropeNamer for CowboyBebopAtHisComputer for a specific example. It's certainly not helped by the AnimationAgeGhetto and [[AllAnimeIsNaughtyTentacles the stereotype that anime is misogynist, tentacle-obsessed trash]].
* This even shows up within manga fandom itself. Creators like Creator/NaokiUrasawa and Fumi Yoshinaga (of ''Manga/AntiqueBakery'' fame) have multiple series published in the US, constantly appear on "best of" lists, and have won tons of awards - yet are virtually unknown outside of the "grown-up comic fans" circle.
* Creator/NorioWakamoto, Creator/RieKugimiya, Creator/JunFukuyama, Creator/KanaeIto, and many other popular Japanese voice actors definitely qualify. Mention the name "Norio Wakamoto" to any random passerby. The chances of it even threatening to switch on a light bulb are low indeed. Even within anime fandom, if a fan primarily watches anime dubbed and/or doesn't interact with fans who concern themselves with the voice actors on the regular basis, it's not unlikely for them to not be familiar with even the biggest names in the anime Japanese voice acting circle.
** Likewise with dub voice actors and anime fans who don't watch dubs. Most of them know Creator/SteveBlum and Creator/CrispinFreeman, but when you move beyond that, you're likely evoke a "Who?" response.

[[folder:Comic Books]]
* Franchise/{{Superman}}, Franchise/{{Batman}}, Franchise/WonderWoman, Franchise/GreenLantern, {{Spider-Man}}, the ComicBook/FantasticFour, ComicBook/{{X-Men}} (at least {{Wolverine}} and possibly Comicbook/{{Cyclops}} and {{Storm}}), ComicBook/{{Aquaman}}, TheFlash, IronMan, CaptainAmerica, {{Thor}}, and TheIncredibleHulk are the only superhero exceptions to this trope. Even then, the only of their supporting cast to be generally known by people are SelfDemonstrating/TheJoker, Comicbook/{{Robin}}, ComicBook/LoisLane, and possibly SelfDemonstrating/LexLuthor and ComicBook/{{Catwoman}}.
** J. Jonah Jameson may have crossed the threshold as well, helped by Creator/JKSimmons' performance in ''Film/SpiderMan'' and its sequels.
* 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, Luke Cage and Black Panther, and [[Comicbook/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 of 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"...
* 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'' or ''ComicBook/{{Watchmen}}'', you're definitely going to hear stories of 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. 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.
* Ask anyone outside of comics fandom to name a comic book writer, and you'll probably get a mention of Creator/StanLee (his legendary cameos in Marvel superhero movies probably help). Maybe Creator/AlanMoore and Creator/NeilGaiman as well, if they're a certain sort of literary. Any other name will be met with a resounding "who?", no matter how popular or prolific they are within the comics industry.

[[folder:Fan Fic]]
* There's a whole subculture dedicated to this. But it's only popular with the geek side of the internet.

* ''BoyzNTheHood'': Which this trope was inversely LampShaded in the film it self by the character Doughboy (quoted above).
* ''Fear of a Black Hat'', contrasted with ''ThisIsSpinalTap'' (which can also fit)
* In an inversion, Australian film critic David Stratton seems to be quite isolated from other forms of media - in his review of ''WesternAnimation/TheSimpsonsMovie'' he said he had never watched ''WesternAnimation/TheSimpsons'', in his review of ''BeeMovie'' he admitted to never having watched ''Series/{{Seinfeld}}'', and he also said he had never read the book ''Literature/WhereTheWildThingsAre'' in his review of that movie.
** Some critics and pundits would argue that such a stance is actually for the best, as it ensures that reviewers will remain unprejudiced toward the film content and avoid HypeBacklash and / or TheyChangedItNowItSucks. One theatre critic, for example, had never seen any incarnation of ''Theatre/WestSideStory'' prior to attending a Broadway revival of it; with this fresh and unjaded perspective, the reviewer was able to honestly (if kindly) evaluate the play's objective worth and point out any flaws it had. (After all, a worshipful attitude often indicates just as much bias as an unreasonably hateful one.)
* The popularity of several cult actors, at most they'll likely just be HeyItsThatGuy! But in certain circles they're as popular as TomCruise, and WillSmith. A few Examples are....
** Creator/BruceCampbell
** Creator/TonyTodd
** [[Film/BlackDynamite Michael]] [[Film/{{Spawn}} Jai White]]
** TiffanyShepis
** Julie Strain: Basically a female Bruce Campbell
** Creator/JeffreyCombs
** Sybil Danning
** Debbie Rochon
** Creator/SummerGlau (arguably anyone who was in ''Series/{{Firefly}}'')
** Creator/AsiaArgento
** Creator/TomSavini
** Beverly Lynne
** Don Wilson
** Christine Nguyen
** Shannon Tweed
** Creator/KaneHodder
** Misty Mundae
** LanceHenriksen
** Shannon Whirry
** Brad Dourif
** Cynthia Rothrock
** Tane [=McClure=]
* Also true about many African-American actors, such as Mo'Nique, Loretta Devine, Angela Bassett, Boris Kodjoe, Music/JillScott, Tracee Ellis Ross, Creator/MeaganGood, the list goes on. Often when African-American actors have a movie that is a crossover hit, that movie will be treated as their first by mainstream media.
** Hilariously demonstrated by Creator/{{Fox News|Channel}} when LL Cool J demanded to have a pre-recorded interview dropped out of a program hosted by Sarah Palin. In an apparent TakeThat, one of the network anchors, referencing his role in the popular ''Series/NCISLosAngeles'', probably the only time most of the Creator/{{Fox News|Channel}} main demographic would have ever seen him acting, said there was no hard feelings and wished him well "[[TakeThat in his fledgling acting career]]". LL Cool J had, at that point, been acting in film and TV for nearly a quarter of a century.
* In the days of drive-ins and regional film distributors, it was possible for a filmmaker to be successful making movies that did good business in one region of the United States, but were almost completely unknown elsewhere. The North Carolina-based Earl Owensby, aka "The Redneck Creator/RogerCorman," is but one example.
* The financial success of TylerPerry's movies, particularly ''DiaryOfAMadBlackWoman'', seemed to catch the mainstream media off guard. Perry had been currying good favor with black audiences through his plays for the better part of a decade, but the white American majority was ignorant of his existence until Madea hit the mainstream.
** The audience for Perry's films are usually black women, a demographic that is either virtually ignored by mainstream films or relegated to a supporting "sassy friend" sidekick for the star. The fact that black woman might want to watch movies where people who look like them want to find some fulfillment out of life besides following their white friends around and supporting them seems have found voice in Perry's works.
* {{Nollywood}} (the Nigerian film industry), despite being the 2nd largest film industry in the world (behind UsefulNotes/{{Bollywood}}), is pretty much only known among Africans, or maybe West Indian people if you're lucky.
** Bollywood itself is almost unknown to Western audiences, despite being the largest film industry in the world.
* [[DiscussedTrope Discussed]] in ''SmokeyAndTheBandit'', when Carrie mentions that Bandit doesn't know much about the theater or any of the things she's interested in and Bandit comes back by saying that she doesn't know anything about people like Richard Petty or Waylon Jennings. "When you tell somebody somethin', it depends on what part of the United States you're standin' in as to just how dumb you are."
* Creator/PriyankaChopra is one of the top actresses in UsefulNotes/{{Bollywood}} and Miss World 2000. In the US, she's probably best known as the singer of the NFL Thursday Night Football theme song, "In My City."

* Southern U.S. folklore probably counts, especially black southern folklore.
** Conversely, any non-black Southern folklore - Cajun, white Louisiana Creole, or various Native American cultures, for instance - will frequently be assumed to be of black origin, even if it can be proved otherwise.
* In one sense, however, it is probably impossible for this trope to exist in the realm of folklore because so many myths and legends are remarkably comparable across cultures.

[[folder:Food and Drink]]
* A lot of region-specific cuisines. Most of what we regard as "typical" American food (hamburgers, hot dogs, etc.) come from the upper Midwest, which is where most middle-class Americans have tended to live.
** This can be said for any type of cuisine. What North America and the United Kingdom consider "Italian cuisine", for example, are only found in the Northern regions, like Tuscany and Emilio-Romagna. The middle and Southern regions, along with the furthest Northern ones, are entirely different (Sicily, for example, is heavily based around fresh Mediterranean vegetables, nuts and fish.) Some areas don't use tomatoes much, if at all.
* Certain soft drinks are only popular in certain regions:
** Faygo is mostly found in the Midwest, specifically around UsefulNotes/{{Detroit}}. It is also a TrademarkFavoriteFood of {{Juggalo}}s.
** Vernors ginger ale was originally tied to Detroit as well, but it is now nationally distributed by Dr Pepper/Snapple. However, about 80% of Vernors sales are still in Michigan.
** Green River sodas are only found in the area around UsefulNotes/{{Chicago}}.
** Grapico, a very popular grape soda is primarily found in Alabama and surrounding states.
** Likewise with Buffalo Rock, a ''VERY'' strong ginger ale that's considerably more popular than Canada Dry.
** Nehi is typically limited to the South.
** While popular in Mexico, Jarritos and sister brand Sangria Señorial are typically found only in the U.S. in areas with prominent Mexican populations.
** Sprecher Brewery of Wisconsin makes root beer and other gourmet soft drinks. While the root beer and cream soda can be found in "normal" grocery stores in Wisconsin and the Upper Peninsula of Michigan, all of their flavors are typically limited to specialty grocery stores elsewhere.
** Briefly averted with Big Red, a Texas-based red cream soda that enjoyed a minor surge in popularity in other states during the first years of the 21st century.
** RC Cola is available worldwide but is massively popular in the American South, where, paired with regional favorite snack food Moon Pies, formed the "working man's lunch."
** A double-subversion: Cracker Barrel stores often stock pop brands normally found only in the South, such as Cheerwine, Dr. Enuf, etc. However, the chain is all but nonexistent on the west coast.
** Moxie is virtually unknown outside of New England...although these days, it's hardly popular; it's one of those LoveItOrHateIt kind of things.
** If you live in Buffalo, you may well love and can name several brands of loganberry juice. If you live anywhere else, you may never have heard of it.
** Ale-8-One is a popular ginger ale soft drink in Kentucky (especially near the town of Wincester where it is bottled), but it is practically unheard of elsewhere. Distribution only expanded to include southern Ohio and Indiana in 2001 according to TheOtherWiki, and it may only be sporadically available in other parts of the Southeast.
* Outside of Alaska and Hawaii, SPAM luncheon meat is only popular among blue collar and low income families. The same could be said for things like ''Potted Meat'', and ''Vienna Sausages''.
* Kool-Aid, similarly could be considered a blue-collar-specific beverage. Which would be ironic, since it was first marketed to middle-class people.
* Blue Moon ice cream is popular in the Great Lakes states (most notably Michigan and Wisconsin), but is virtually unknown anywhere else. This is complicated by the fact that what exactly Blue Moon tastes like is almost as unique as the vendor who sells it, with flavors ranging from almond to spices to cola (although ironically WordOfGod says "true" Blue Moon is NOT "tutti-frutti" or blue raspberry).
** And in Oklahoma and Texas (and possibly other states in the same geographical area), Blue Bell ice cream attracts a fervent following not understood by anyone outside of the area that Blue Bell serves. This is purely the company's intent, though; the higher-ups wanted to make sure the ice cream was as fresh as possible, so have never really thought of expanding nationwide.
* And speaking of Texas, the Whataburger fast food chain attracts an almost scarily devout clientele of people who simply cannot get enough of their food, particularly their burgers and chicken sandwiches. In Texas, unless you're a vegetarian, you'll have your favorite Whataburger menu item, whether it be one of their specialty sandwiches (such as the A1 Thick & Hearty Burger or the Monterey Melt) or a specific way you order your regular Whataburger (e.g. a bacon cheeseburger with mayo and mustard [the default condiment is mustard], no onions, extra pickles, and on Texas toast [instead of a regular bun]).
* Caviar. Admit it: unless you were reared in an old-money family or are from Russia, Central Europe or environs, you spent practically all of your childhood completely in the dark about what that was. (For the record, the top brands of caviar are made from salted and pressed sturgeon roe, generally harvested from the Caspian and Black Seas, and are stupidly expensive and usually only available from luxury goods shops. In Western Europe there are cheaper brands available, made from things like lumpfish and salmon roe, which you can buy in supermarkets.)
* Eagle Brand baby formula and dehydrated milk products are so ubiquitous on certain Southwestern US Indian reservations that they're mentioned by name in the phrasebook at the back of the best-selling Navajo dictionary. Probably nobody not from one of those Indian reservations, or near them, has even heard of it.
* Very few people outside Michigan will know what a "[[https://en.wikipedia.org/wiki/Coney_Island_hot_dog coney dog]]" is. But if you live in Michigan, particularly around Flint or Detroit, the "coney island" restaurants that serve them are ''everywhere''.
* Also speaking of Michigan, the Upper Peninsula (UP) offers the pasty (pronounced "PASS-tee", not "paste-y"), a pie stuffed with meat and vegetables. They were brought by migrants from Cornwall in the late 1800s, who went to work in the region's then-numerous copper mines, and they remain a part of UP culture to this day. Show the word to anyone else, though, and you might get "Oh, isn't that a thing that strippers wear?"
** Pasties are still very popular throughout Britain, with various bakery chains that sell them as a popular street snack food. In fact, there was even a minor, unpopular political policy (a 5p tax on shops selling 'food above room temperature) that got nicknamed "the Pasty Tax".
* Ask anyone who has never lived in the Delaware Valley/Greater Philadelphia Area what a Wawa convenience store is. Be expected to be met with blank stares. (They also have locations in New York, Maryland, Virginia, and Florida, but these are largely localized to areas with lots of Philly transplants.
* In the Southeast, shopping malls often have a cafeteria-style restauarant in them, such as Piccadilly or K & W, alongside or in place of a food court. Such chains sometimes have standalone cafeterias, too. Elsewhere, the cafeteria chains are almost entirely unheard of (barring a handful of MCL Cafeterias in Indiana), and can come across as strange to those expecting a more conventional restaurant in a mall.
* Chinese food. Much of what you find on the menu at a typical take-out, like General Tso's chicken, pork fried rice, chow mein, sweet & sour chicken, etc., are purely American inventions. Chinese expatriates more or less refer to American-Chinese cuisine as essentially a lie. Pinpointing what could be considered Chinese food would be a problem [[http://en.wikipedia.org/wiki/Chinese_cuisine as it's extremely diverse]], to the point that no two households are likely to share the same tastes.
** Hilariously, "Chinese"-food restaurants are starting to open in China, mostly because tourists who travel to China expect "Chinese" food. RealityIsUnrealistic, indeed.
** Dim sim (Not to be confused with Dim sum) is Chinese-inspired, but is actually Australian. However, many assume that they are completely Chinese.
* Italian Beef sandwiches (also known as "beef sandwiches" or even just "beef") are virtually unknown outside of the [[UsefulNotes/{{Chicago}} Chicagoland area]], where they are wildly popular. To the point that some stands will specialize in beef sandwiches (or make only beef), and can even be found in the deli section of local stores. Portillo's (a fast food restaurant chain that sells beef sandwiches alongside hamburgers and hot dogs) has opened franchises in California, but they still remain obscure outside of a very small section of the Midwest.
* On a related note, loose-meat sandwiches (often called "Maid-Rites") are extremely popular and prevalent in the Midwest, but virtually unknown outside it (or confused with Sloppy Joes).

* ''Literature/{{Phenomena}}'': is quite a big hit in Norway with the books often sold out in bookstores and the board game is completely out of stock. It has been translated to only a few languages, making it very little known about with other people around the world.
* {{Zane}} novels, black erotic literature, probably count.
* You probably know the CthulhuMythos. You probably also know who HPLovecraft is. But do you know the names of Jim Turner, Robert Bloch, or Robert M. Price? No, Lovecraft didn't write ALL the Mythos. It's actually sort of like 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-Soggoth, Azazoth, or Nyarlathotep.
* Young adult literature, obviously. Because these novels and short stories are read neither by single, middle-aged or elderly adults (unlike generally "serious" fiction, which is acknowledged by critics and the media) nor by young parents with prepubescent children (as is Dr. Seuss, etc.), they are relegated to the readership of adolescents and tweens, whom mainstream culture tends to ignore except as a marketing demographic (and today's businesspeople are not trying to sell a lot of books). Go ahead: ask your typical fiftysomething Baby Boomer who Wilson Rawls was; they probably won't remember, if they ever knew about him to begin with.
** Some series, such as Literature/HarryPotter and Literature/TheHungerGames, do manage to "cross over" and become popular with audiences [[PeripheryDemographic outside their intended 12-19 year old demographic]].
* Same thing could be said for SpeculativeFiction (''SciFi'', ''{{Fantasy}}'', and ''{{Horror}}''). This also swerve into SciFiGhetto territory as well.
** For Sci-Fi, the Big Three of Creator/IsaacAsimov, Creator/RobertAHeinlein, and Creator/ArthurCClarke are most likely to be known, at least in regards to their most famous works. Fantasy writers are limited to Creator/JRRTolkien and Creator/JKRowling, and then only as the authors of Literature/LordOfTheRings and Literature/HarryPotter, respectively. Creator/GeorgeRRMartin is starting to become this as well, thanks to the popularity of the TV series ''GameOfThrones'', which is based on his series ''Literature/ASongOfIceAndFire'', but even there, they probably don't realize he's written anything else. The only well-known modern Horror writer is Creator/StephenKing.
* InUniverse example meets TruthInTelevision in Creator/JorgeLuisBorges short story '' "Averroe's Search" '': Averroes, a philosopher confined to the Islamic orb, never could understand the terms ''Tragedy'' and ''Comedy''.
* It's amazing how many people appear not to have heard of Creator/TerryPratchett, even though he is the second most-read author in the UK, and the seventh most-read author in the USA, across all genres. One newspaper interview lampshaded this with the introductory paragraphs including the line "Terry Pratchett, for those of you still pretending to have no idea who I'm talking about, is..."

[[folder:Live Action TV]]
* The TV series ''Series/TheGame'' is one of the most, if not the most, popular drama/comedies in the black community. Most white people aren't even aware the show exists. The show is now on Creator/{{BET}} but even when it was on CW, it never really found a strong white audience.
* GeorgeLopez and Creator/ChrisRock are interesting examples since before they had their own self titled sitcoms they were well known, but they weren't ''well liked'' by anyone outside of their targeted demographics.
* Steve Harvey is a very popular comedian in the black community, but not too many people outside of it even know he exists. He arguably may have overcome this due to his sitcom, and appearing in ''The Kings of Comedy''. And taking over as the host of ''Series/FamilyFeud'' in 2010. And then getting his own talk show in 2012.
** This is arguably true of most Black comedians before they land a sitcom deal, or hell, any comedian since they tend to only be popular within a certain niche (women, college students, blacks, Latinos, Asians, other ethnicities, etc.)
* ''TheCosbyShow'' subverted this; on the other hand, it was Creator/BillCosby's intention.
* ''{{Roseanne}}'' contrasted with TheCosbyShow, Not in terms of race, but class. In fact, you could swap out ''Roseanne'' for ''GoodTimes'' and get the same results.
* {{MTV}} was also the cause of a lot of this, so much so that MTV refused to acknowledge that 90% of the songs on the chart were by black singers and kept trying to push a next Big White Hope like Winger or Warrant. There was such an embarrassing disconnect between their Top 20 played videos and the Billboard charts back then. DavidBowie [[CrowningMomentOfAwesome awesomely]] called them out for it during a interview with the network. They eventually caved in with the meteoric rise of MichaelJackson though.
** TheNineties version of MTV subverted this trope, though, by basically not putting music in a box or programming block (Yo! MTV Raps, 120 Minutes, and Headbanger's Ball being the exceptions). On the other hand, this might be why they started putting music in a programming block and eventually [[NetworkDecay stopped showing vids all together circa the early 00's.]] Simply put, nobody was gonna wade through rap vids to see a rock vid or vice versa.
* The popularity of ''{{Martin}}''. VH1's ''I Love the '90s'' actually brought up that the show was virtually unknown to white viewers, in part because it was scheduled against ''{{Seinfeld}}''.
* Similarly, ''Series/LivingSingle'' contrasted with ''{{Friends}}'', some even going as far as to say the latter ripped off the former or at least inspired by it.
* According to VH1 Classic, New Wave and Hair Metal were the only music genres in TheEighties. Care about [[CollegeRadio college]] [[AlternativeRock rock]] or old school hip hop? Hope you're willing to stay up until 3:30AM!
** VH1 Classic's ''ThatMetalShow'' definitely seems to have a bias towards hard rock and heavy metal bands from the 70s, 80s, and 90s. Interviews with metal musicians from more recent bands are few and far between.
* ''Series/DoctorWho'' provides an age-gap version of this trope all by itself; there are passionate fans of the series who either had (or continue to have) no idea that there was a show before 2005 and / or have no interest in watching any of the old series.
* As surprising as it may seem on the Internet, there are other TV shows beside ''Series/BreakingBad'', ''Series/GameOfThrones'', ''Series/DoctorWho'', ''Series/{{Sherlock}}'' and ''{{Series/Supernatural}}''. There are still lots of people who don't subscribe to premium cable channels or subscribe to cable at all.
** And who presumably do not [[NewMediaAreEvil illegally download]] them.
* In-show example: in the BBC documentary ''Deborah 13 Servant of God'' (about a young girl from a fundamentalist Christian family who was very zealous in her faith) there was one point where she is asked if she'd ever heard of the likes of Music/BritneySpears- and being not immersed in popular culture like most teenage girls (having no television, being homeschooled etc.) she didn't. In response, however, she asked if most people knew who a certain (fairly obscure) Biblical character was.
* Arguably one factor counting for the success of ''TheArsenioHallShow'' in TheNineties was the fact that he, being a hip, younger, black late night talk show host in a field mostly populated with older white hosts and audiences, booked celebrities, politicians, music acts, activists, etc. (particularly those who catered to urban audiences or were in an ethnic or sexual minority) that his competition would rarely to never touch, while still being mainstream enough to appeal to a mass audience. Ultimately this would help Arkansas governor UsefulNotes/BillClinton reach audiences he likely would never reach on other talk shows, which would help him get elected in 1992.
* Christian-themed television shows can be slightly puzzling to non-Christian viewers. ''Series/TouchedByAnAngel'' is probably the most prominent example of this; it lasted for 9 seasons mostly off the backs of its devoutly Christian audience.
* ''Series/AlmostLive'' was a LongRunner in UsefulNotes/{{Seattle}} and a television icon. ''Series/MadTV'' was not even going to be ''shown'' in Seattle because Creator/{{FOX}} didn't think the show could stand against it. Even now, you could probably get half of the city to give up coffee for a month to get a box set [[note]]And considering this is a town with [[MustHaveCaffeine 2-3 espresso carts per block]], that's saying plenty[[/note]]. When Creator/ComedyCentral picked it up during the Nineties, during the world's grunge-induced fascination for all things Seattle, it crashed and burned hard because much of the humor was based on local-area customs and stereotypes. It was still a great springboard for ''Series/BillNyeTheScienceGuy'', however.
* An interesting example of Genre overlapping with Region. In the 80s, Canada began to aggressively court American film and television producers as a relatively cheap filming location due to the exchange rate between the US and Canadian dollars. The one genre that really snapped this up was sci-fi/fantasy (''Series/TheXFiles,'' The ''Franchise/StargateVerse,'' ''Series/{{Smallville}},'' ''Series/{{Supernatural}},'' ''Series/{{Arrow}}'', ''[[TheFlash2014 The Flash]]'' etc.) possibly to allow the lower production costs to offset the higher special effects costs that sci-fi inevitably has. Due to the use of local Canadian actors, it creates the interesting situation of Canadian actors being easily recognizable to American sci-fi/fantasy fans, but unknown to the mainstream. A similar effect happens with the combined talent pool of Australia/New Zealand, thanks to New Zealand-filmed shows such as ''Series/HerculesTheLegendaryJourneys,'' ''Series/XenaWarriorPrincess,'' ''Franchise/PowerRangers'' and ''Series/LegendOfTheSeeker,'' alongside ''Film/TheLordOfTheRings.''

* ''Rolling Stone'' and similar mags have been accused of having a rock bias.
** ''RS'' in particular is accused of 60s-70s bias in their lists.
* ''The Source'' magazine, or any genre specific mag is this by default.
* Lowrider mags, vs custom car mags (like DUB magazine), sport tuner car mags, and American muscle car mags. There's over-lap but they're somewhat significantly separated. Plus each scene has its own car culture, and preference of female models. Mags like DUB almost always have black girls AND Hispanic females, whereas the lowrider mags are more or less exclusively Hispanic, the tuner mags are almost always southeast Asian, and the muscle car mags are almost always white.
** Illustrative example: Ask a gearhead what a "Donk" is and he/she will reply that it's any car with huge rims, very thin-walled tires, a very expensive and flamboyant paint job and other hallmarks of "bling." Ask an editor at a Lowrider mag (or any "authentic" Lowrider enthusiast) and he/she will tell you that it's specifically a 1970s Chevrolet Caprice (independent of whether or not it's stock or blinged out - it's just a slang term for that specific type of car. He/she will also tell you that "Bricks" are 80s Caprices and "Bubbles" are 90s Caprices due to their general shape). Of course, ask an average person on the street and expect to get a blank stare.
* When ''FineScaleModeler'' did an article on GunPla -- the hobby of building Franchise/{{Gundam}} plastic model kits -- it was an unusual and controversial step. This despite the fact that the GunPla market ''dwarfs'' FSM's target market, American modelers of realistic vehicles.
** this is not unknown in the plastic modelling community; in Great Britain, the "orthodox" historically-based hobby tends to look down on sci-fi and fantasy modellers. The respective readerships of ''Military Modelling'' and ''WhiteDwarf'' do not overlap, and Warhammer topics almost never make it into the "mainstream" modelling press - MilMod got complaints from readers when it tested this particular water.

* OlderThanTelevision: RAndB of the [[TheThirties 1930s]] and [[TheForties 1940s]] was generally known only to black people due to segregation. This isolation was made clear by a name given to R&B back then -- "race music". The same happened to {{Jazz}}, {{Blues}}, and RockAndRoll.
* Most pop-culture music trends start out this way. PunkRock (the American version, at least) started out in lower Manhattan sometime in the mid-[[TheSeventies 1970s]] and slowly gained a following in other big cities across the country before finally breaking through to the mainstream. Similarly, HipHop began in the Bronx and only gradually spread throughout the rest of New York and then to Los Angeles before going nationwide.
* The British parallel concerns a cultural establishment - including big radio and TV names - who are based in London, consider the London scene is all and everything (and dismiss the rest of the country as "provincial"). Therefore they fail to notice what's going on outside London and only register it either when it moves South or it gets too big to ignore. Examples: "[[{{Soul}} Northern Soul]]", a specific sort of soul beat popular in Wigan and the North-West, so popular that people from all over came north to join in, but largely ignored by the establishment. Or the way northern groups were ignored - the myth grew that PunkRock was solely a London creation and bands from other parts of the country were simply imitating. (as the British provinces are of course populated by people incapable of creativity.)
** A modern example is the rise of Garage, Grime and Dubstep music. Whilst not unheard of elsewhere, it surprises many how popular they are in inner city London.
** Lots of bands in Sheffield were early adopters of synths and other electronic influenced music in the late-1970s but they stayed underground until The Human League, Heaven 17 and ABC suddenly hit the mainstream in the early 1980s. In general the Sheffield synth-pop scene often gets overlooked in histories of UK music.
* {{Grunge}} was very popular among young white youth. But young Blacks and Latinos for the most part were somewhat oblivious to it. The Lollapalooza tour helped bridged the gap a little.
** The reason hip-hoppers were oblivious to the grunge movement was because HipHop was going through what some would call a GoldenAge renaissance. NostalgiaFilter card aside, most fans believe ''1994'' alone crushes everything that came out in the past decade. Some argue that that era was a really, ''really'' good time period for HipHop and its fans. So basically, many Black/Latino youth were preoccupied by their own cultural rise.
* The Mexican-American singer {{Music/Selena}} might also count. [[DeadArtistsAreBetter How many of you knew of her]] ''[[DeadArtistsAreBetter before]]'' [[DeadArtistsAreBetter she died]]?
** Right after she died, and her murder was being covered nonstop in the press, ''People'' magazine put out an issue with Selena on the front -- but only in the Southwestern US. (The rest of America got a cover with the cast of ''{{Friends}}''.) They were probably figuring the only people who were interested in reading about Selena (AKA Latinos) were all living in that area. Except that issue not only outsold the ''Friends'' one, but also went through several reprints. It ended up spawning only the third full commemorative issue in that magazine's history, and led to the creation of ''People en Español''. The people at the magazine grossly underestimated not only mainstream interest in Selena, but also the significant consumer power of the Latino community.
* Some say this trope created [[http://en.wikipedia.org/wiki/Rockism rockism]].
* During the documentary ''Pump Up the Volume'' (a docu-series about the rise of HouseMusic, {{Techno}} and the whole Detroit/Chicago/New York scene.) One guy was discussing the backlash against {{Disco}} around that time. He said there was a bonfire where people were standing in a line throwing in disco records (Now if you're GenreSavvy enough you know where this is leading), similar to Chicago's [[http://en.wikipedia.org/wiki/Disco_Demolition_Night Disco Demolition Night]]. He began to notice that most of what they were burning [[UnfortunateImplications isn't disco, but just black music in general]]. [[http://www.youtube.com/watch?v=Jd8W7pbxTsQHe said he saw one guy with a]] Music/MarvinGaye record in his hand. This is also a double example as around this time House was only thriving in Chicago, and the New York underground.
** The same documentary noted that Chicago House music first really took hold in the UK in Northern discos (such as the Hacienda in Manchester), then via DJs on holiday islands like Ibiza, and finally becoming mainstream by reaching London.
** Many listeners dismissed disco as "too black" or "too gay," or both: making it the musical sub-genre equivalent of a TwoferTokenMinority.
** On a similar note, how many urban black people can tell you the difference between Music/{{Aerosmith}} and Music/AliceInChains? Keep in mind rock is almost non-existent on black radio, so the popularity of these bands probably flew over their heads (unless you include the general mainstream media which is biased toward rock anyway). Or how about the fact some blacks got into rock thanks to bands like Music/FaithNoMore, and Music/LivingColour during the late [[TheEighties 1980s]], and NuMetal during the late [[TheNineties 1990s]] and early [[TurnOfTheMillennium 2000s]] due to them incorporating HipHop, Funk and rhythm, or soulful vocals in Corey Glover's case? There's also the fact that some suburban whites can't tell you the difference between Music/BoneThugsNHarmony and Music/RunDMC To outsiders, rap music might as well all be the same.
*** There's always a segment of black people with a vested interest in rock music, at least stemming from the fact that rock came from black singers such as Music/ChuckBerry. But not as much as say HipHop and R&B.
* A funny sub example of this trope is that of singer Dionne Farris. Ask a white suburban person what song they know by her and they'll almost always say "''I Know''" (a Pop/Alt/rock song). Ask black urban music listeners and they'll say the song "''Hopeless''" (which is a down tempo soul song). The contrast is jarring, and funny.
* Another example is modern radio. Which is heavily segre...uh...divided up.
** This specific example might be at the heart of why Music/{{Anastacia}} has had almost no luck breaking into the U.S. market. A massive success all across Europe and Asia, she is still a relatively unknown in the U.S., despite the fact that she herself is from Chicago. It's believed that since American radio is heavily format-driven and sharply divided, there isn't really a place for her eclectic sound to fit. Essentially too soulful for A/C stations, and not urban enough for urban radio stations, and not poppish enough for top 40, and not rockish enough for rock stations. No one can really seem to figure out what to do with her.
* A inverse hip-hop example is from the east coast rapper Jadakiss when he asks "Why my buzz in L.A. ain't like it is in New York?"
** Hip-Hop somewhat had this bad. If you're not a hardcore meticulous HipHop connoisseur who actively seeks out artists on your own, you probably missed out on a lot of regional acts. As radio from each region had different and diverse play lists. So whomever was popular in in the Northeast might not be as popular in the Southwest. For better or for worse it's different now though, as most stations tend to follow a ''VERY'' strict playlist. And for the most part they're more or less the same around the country. Likely because [[MusicIsPolitics most radio stations are corporate owned now instead of privately owned]].
** Music/QueenLatifah said if it wasn't for rappers like Music/{{NWA}} she wouldn't have known what life was like in south central LA.
* Go to a few rock concerts and you'll see a sprinkle of a few black kids, But not a lot.
** In the documentary ''[[http://en.wikipedia.org/wiki/Afro-Punk_%28film%29 Afro Punk]]'', some of the black kids that were interviewed said that they didn't always feel accepted. Or when they did get acceptance, it felt like it was for [[ButNotTooBlack the wrong reasons]] to them.
* When {{Eminem}}'s third album ''The Eminem Show'' was released, two different singles were promoted at the same time on different genre stations. "White America" was mostly played on the rock stations, while "Cleaning out my Closet" was played on hip-hop stations.
** TLC's ''Unpretty'' had 2 different versions released for radio. One was a "Urban" mix, and the other was a mix for pop radio. The latter was the original version though.
* There's a lot of guitarists out there who are revered and recognized and put on a lot of top guitarists list. Guitarists like Steve Vai, Eddie VanHalen, etc. But you'll be hard pressed to see people like [[LivingColour Vernon Reid]], [[Music/DreamTheater John Petrucci]], and [[TheIsleyBrothers Ernie Isley]] mentioned, or listed though. Exceptions being the politically correct choice of JimiHendrix, and MAYBE Eddie Hazel...maybe.
* Clive Davis ''INTENTIONALLY'' invoked this when marketing Whitney Houston. Primarily by sending her exclusively to A/C radio stations instead of urban radio stations.
* This might have been the seed that help formed "''The Black Rock Coalition''"
* NewEdition contrasted with NewKidsOnTheBlock, This is believed to be why the latter was created in the first place. Maurice Starr was apparently very GenreSavvy.
* ThreeSixMafia LampShade this with the album title "''Most Known Unknowns''"
* This trope possibly explains the sub-culture division among 40 somethings when it comes to black music. In the beginning when hip-hop was in its infancy in the early eighties, only a hand full of 20-somethings were caught up in the culture of HipHop, while the majority of the other 20-somethings were still into the post-disco/R&B new wave funk scene. This explains the cultural schism of 40-something African Americans regarding the hip-hop culture, and why you have 40-something hip-hoppers and hip-hop artists, and 40-somethings who are outside the culture, despite being young adults around the genre's inception.
* It can still be true today with R&B. Everybody knows AliciaKeys, {{Beyonce}}, and {{Rihanna}} but very few people know IndiaArie, Maxwell, Musiq Soulchild etc. outside the African-American community.
* Similar to the ''NewEdition'' and ''New Kids On The Block'' example; There was ''Pat Boone'' who used CoveredUp as a way to market black music to whites. But all it did was veer into UnfortunateImplications territory..
* Robyn had a "urban mix" for "Do You Really Want Me" for urban radio stations. She also counts in another way in that some think she's a new artist, but she's been around since 1995.
* ArcadeFire took home a Grammy for Best Album in 2011. They're not signed onto a major label, and apparently not known by a very large portion of the population, prompting various [[MemeticMutation "WTF WHO ARE THESE GUYS AND WHY'D THEY TAKE GAGA'S BEST ALBUM AWARD?" Tweets and Facebook posts]].
** Chronicled in [[http://whoisarcadefire.tumblr.com/ this Tumblr blog]], with a heaping helping of FanDumb.
* This is also the reason why many R&B/Pop artists usually have to release two singles at a time: one for pop radio and the other for the urban market.
** Music/{{Beyonce}} basically had a DistinctDoubleAlbum (''I Am...Sasha Fierce'') for this - one side being the soft pop ballad and the other being urban jams. She released "[[TheUnfairSex If I Were A Boy]]" mainly for pop radio and "Single Ladies" for the urban market. The experiment [[GoneHorriblyRight Succeeded Too Well]] and the biggest hits from the album were only the urban songs.
** ChrisBrown is balancing his ''F.A.M.E.'' album to have pop and urban singles and released the poppy "Yeah 3x" to pop radio to compliment "Deuces".
** Usher had the megahit ''OMG'' that topped the pop charts and didn't really make a dent in the urban market.
** And, in 2010, Creator/KellyRowland released ''three'' singles, each for different market - "Commander" for international (i.e. non-US) audiences, "Rose Colored Glasses" for American pop radio, and "Grown Woman" for the urban market.
** Ce Ce Peniston might have been the prototype, with one foot in house music, and the other in R&B/New Jack Swing.
* For not only a whole generation but perhaps a largely white audience who grew up with Music/PhilCollins as the drummer (and later, also lead singer) of Music/{{Genesis}}, his transformation from white British art-rocker with hair down to his belly and a long white robe singing about squonks and eleventh Earls of Mar to [[TheEighties 1980s]], commercial, electronic blue-eyed soul/funk/soft rock singer in a suit and tie singing "Su-Su-Sudio" can be [[BrokenBase controversial]]. For a generation (and skin color) who know Phil's pop hits through black radio playing his MTV-era hits and who wouldn't necessarily pick up a copy of ''A Trick of the Tail'', you would have the likes of Music/IceT put in his place a white, smarmy, hipster rock journalist picking on the Phil Collins [=CDs=] in Ice's collection during an interview with Ice by responding, "Don't you mess with my Phil!"
** Similarly, the GenreShift that TheDoobieBrothers took by [[TheSeventies the late '70s]] from guitar-driven country-rock (with mild R&B influences) led by Tom Johnstone ("Listen To The Music"; "Black Water"; "Long Train Runnin'"; "China Grove") to the keyboard-heavy blue-eyed soul style led by MichaelMcDonald ("Takin' It To The Streets"; "What A Fool Believes"; "Minute By Minute"; "You Belong To Me") might possibly be more of a shock for white rock audiences than urban black audiences who would be less likely to pick a copy up of ''Toulouse Street'' or ''What Were Once Vices Are Now Habits''.
* Similar to the Dionne Farris example above, this trope can apply to {{Signature Song}}s as well. If a artist is popular in more than one demographic it's ''HIGHLY'' likely that each group has their own opinion of what that artist's signature song is.
* The death of R&B singer Music/{{Aaliyah}} completely gutted the HipHop and R&B community with huge outpourings of mourning and tributes. When it came around to the mainstream media to react, most of the entertainment news outlets (that primarily cover white celebs) didn't even have her death as the ''top story'', and they had to use Gladys Knight (Aaliyah's former aunt and close family friend) in order to make her more relevant to that audience.
** Same could be said for the aforementioned Selena.
** Ellen [=DeGeneres=] touched upon this when ''TupacShakur'' died. Noting that the mainstream media were more interested in her coming out of the closet.
** [[http://panachereport.com/channels/old_school_update/BlkCelebsDied.htm This is fairly common with black celebrities]]
* Like the Whitney Houston example above, the same could be said for *Music/{{NSYNC}}. This trope combined with the ButNotTooBlack trope was how they were marketed by their handlers. They didn't start courting urban audiences till the ''Celebrity'' album.
* It is ''fiendishly'' difficult for JPop and KPop artists to cross over to American shores. Even UtadaHikaru (who is ''American'') has had a difficult time despite switching up the production of her second U.S. album. And she's one of the most popular music artists in Japan and still has the worldwide record for most albums sold in a week. Both she and Music/{{BoA|Korea}} tried for U.S. success, but couldn't expand beyond the people who already were fans. The only KPop artist most Americans are familiar with is Music/{{Psy}}.
** Between both of the genres however, KPop has a slight edge over them as the genre is very popular among Asians while JPop at the moment is stuck in its own nation.
* Instead of making a straight dance song, a lot of singles from the early-90s on come with dance mixes to get play in clubs and on dance radio shows, adding in bigger beats and a beginning drum track for transitions. Depending on the release, these tracks might be included as a bonus track on an album, on the single, or only on a special "DJ Mix" single. This means if you don't hear it in a club, you probably won't hear this version at all. This was even done in ''country'' music, where songs already suitable for line dancing had the beat jacked up and an extended bridge.
* A main cause of CoveredUp, where an artist in one genre covers a song from another.
* CountryMusic. According to one survey, 38% of American adults are country music fans... but 25.4% of that group ''only'' listens to country music. While the stereotype of country music listeners being exclusively down-market blue collar types is no longer true, regional and demographic appeal does vary. Some urban markets have few to no country stations, with NewYorkCity not having one for years until 2013, when a commercial owner bought Family Radio's east coast flagship and converted it to the homogenous "Nash FM", a format which only plays the same few 'new country' songs. And with that, little to no knowledge of any country act who hasn't crossed over into pop (e.g. Music/TaylorSwift and Music/LadyAntebellum). On top of that, country is also one of the whitest genres by far — Music/CharleyPride and Music/DariusRucker (yes, the guy from HootieAndTheBlowfish) are pretty much the only black country artists who have had any long term success.
** On the religious side of this, Gospel music, often called Southern Gospel to distinguish it from the very different-looking and sounding Black Gospel, has this in spades. At one time it was the most popular form of Christian music outside of church hymns, but these days it is distinctly a niche market and one that is hemorrhaging fans at an alarming rate as it primarily appeals to people who were young when the genre became popular. But ask a Southern Gospel fan and you'd get the impression that it's still the only "real" Christian music out there, and the current groups (most of which perform mostly in churches to crowds of less than a hundred) are super-stars that everyone knows about. The groups themselves usually have side-jobs because performing in this genre doesn't pay well, and often break up due to not being able to so much as break even. If you're a Southern Gospel fan, you likely believe the Inspirations, Ernie Haase & Signature Sound, Gold City, the Kingsmen, the Nelons, Karen Peck & New River, Greater Vision or the Booth Brothers are incredibly popular. If you're not, you likely have never even heard these names before, even if you're a regular church attender.
* As far the UnitedKingdom is concerned, pop music in languages other than English ''does not exist''. The fact that most Brits are hopeless at foreign languages doesn't help.
** Very, very occasionally a song in French ("Dominique", "Je t'aime"), German (Kraftwerk's "Autobahn"), Italian ("Vado Via"), Spanish (Los Lobos's cover of "La Bamba") or ecclesiastical Latin (Steeleye Span's cover of "Gaudete") will hit the British charts. These average about one a decade, discounting things like the Beatles' ''Michelle'' (the French bits are a bit pidgin). Usually the only way to get a true international hit is to be completely instrumental or only have limited English within a song (Eiffel 65's "Blue"). The last foreign-language hit was probably O-Zone's Dragostea Din Tei (Romanian) in 2004.
* This likely played a part in MariahCarey's BrokenBase. When her music became more urban and less adult contemporary her fans whined about the inclusion of HipHop. Some even went as far as blaming the change on the insecurities she have regarding her cultural background and ethnicity.
* This is the case any time artists commit GenreAdultery. It's hard to sell a new genre to your fan base who is only used to the genre you are known for doing.
* Music/DaYoopers. Extremely popular in Michigan (particularly the Upper Peninsula, from which their name is derived) and Wisconsin, where countless stations will play "Second Week of Deer Camp" around hunting season in November, and "Rusty Chevrolet" around Christmas. Outside maybe one or two stations here or there, they're almost total unknowns. It probably doesn't help that many of their songs are local in nature, and that they've always been on limited distribution on their own label.
* Unless you were a member or were a band kid in school, you have probably never heard of the Blue Devils, Carolina Crown, the Cadets, Santa Clara Vanguard, Phantom Regiment, or the Cavaliers. In case you're wondering - they're drum corps.
** Even within the drum corps fanbase, there is a lack of familiarity with the all-age circuit (as opposed to the above junior corps, where the maximum age is 21), since it is primarily a Northeast regional phenomenon. However, a number of corps from outside the region (Minnesota Brass Inc., Atlanta CV, San Francisco Renegades) have made inroads into that circuit.
* This trope was very deliberately [[SubvertedTrope subverted]] with HallAndOates in TheEighties. They noticed, certainly after disco died, how racially segregated white and black radio stations were becoming, and sought to create a blue-eyed soul/pop/new wave/rock/dance style that was partly informed by white and black influences and would appeal to both audiences, which they succeeded in doing for the first half of that decade.
* UK and Irish boy bands have gone largely under the radar in the US. Acts like Music/TakeThat, Westlife, Boyzone, and Five all tried to gain American popularity but were rejected in favor of American boy bands like Music/{{NSYNC}} and the Music/BackstreetBoys. In fact, only one British boy band has ever had a successful American breakthrough: Music/OneDirection (and that was almost 15 years after the aforementioned boy bands peaked).
* Amongst the general public, Music/NatKingCole is acknowledged as a great singer, for classics like [[https://www.youtube.com/watch?v=vDN5rG3wLa4 “Unforgettable”]]. Amongst musicians it’s understood his real contribution to music was revolutionising jazz piano playing. This is to the extent that his brilliant innovations provided a bridge towards a style of piano playing that fit bebop.
* Many underground/internet phenomenons, even after they break through to larger audiences. LanaDelRey is a good example.
* TheDecemberists, unless you live in the Pacific Northwest or are an indie fan.
* Anything Macklemore did before ''The Heist'' is fairly unknown unless you are from the Seattle area. Even fewer people know anything about Ryan Lewis, his producer, besides his name.
* WeirdAlYankovic doesn't exist unless you're a geek, you lived during TheEighties, or both.
* Music/JudasPriest is one of the oldest and most influential heavy metal bands of all time. Most metal fans, regardless of their favorite subgenre, have a deep respect for the band and can name a lot of their songs. Despite this, Judas Priest isn't very well known in the mainstream. Their biggest hit, "You've Got Another Thing Coming", peaked at number 66 on the UK singles chart and number 4 on the US rock chart in the year 1982.
* Social media activity during [[EurovisionSongContest Eurovision]] is split into two categories: Europeans (and, [[GermansLoveDavidHasselhoff rather curiously, Australians]]) talking about it and Americans asking "What the hell is Eurovision and why is everyone talking about it?"
* In 2014, {{U2}} released their new album on iTunes, and even "sent automatically" to many iPhone users. Reactions included a whole {{Tumblr}} regarding "[[http://www.whoisu2.com/ Who Is U2]]" tweets. (most who don't know Bono and co. are either young fans of OneDirection or Black people)
* Music fan communities. 90% of the time pop artists' fan followings come up in the news it's either Justin Bieber's fans or One Direction's (although as of 2014 it's usually only the latter). You almost never hear about [[Music/LadyGaga Little Monsters]], [[Music/KatyPerry KatyCats]], [[Music/MileyCyrus Smilers]], [[Music/BrunoMars Hooligans]], etc. unless you're an avid fan of pop music or part of a fandom. This is mostly because the former two fanbases are (or were, in Bieber's case) significantly larger than others. Male idol singers and boy bands (i.e., The Wanted, Big Time Rush, Austin Mahone) are disadvantaged in that the most popular acts typically have so tight a monopoly on the the teenage girl demographic that it's almost impossible for any of their peers to break through. Older male acts and groups (i.e., Bruno Mars, Justin Timberlake, Maroon 5) typically don't cater to a rabid teen audience and are instead fueled by their universal appeal. Female acts (i.e., Katy Perry, Rihanna, Taylor Swift) have a similar mass-appeal factor, but boys don't idolize musicians the same way girls do, the female demographic they do appeal to is nowhere near as enthusiastic for female music idols as for their male counterparts, and the remainder of their fans are gay males, which makes up less than 3% of the population.
* Very few non-Australians can name a boy band from down under other than 5 Seconds of Summer.

[[folder:New Media]]
* A lot of Internet culture and {{meme}}s cause this.
* [[TheSlenderManMythos The Slender Man]] is relatively unknown outside of a relatively large group of fans on several forums. Though ''{{VideoGame/Slender}}'' and [[VideoGame/SlenderTheArrival its sequel,]] in addition to the ''[[WebVideo/MarbleHornets Marble Hornets movie]]'' being made, and [[NoSuchThingAsBadPublicity those Slender Man inspired stabbings,]] are turning the Slender Man mainstream.
* Website/{{Youtube}} user Hola Soy German is really popular in Latin American countries, to the point where he has over 18 million subscribers, but is virtually unknown outside of Spanish speaking countries, to the point where he didn't have an article on TheOtherWiki until May 2014 and currently doesn't have an article on ThisVeryWiki.

[[folder:Newspaper Comics]]
* ''TheBoondocks'' managed to overcome this.
* Indeed, most comic strips start out in only one newspaper (usually a paper in a region of a country where the cartoonist works) and ''then'' are nationally syndicated, sometimes not until years later. More than a few strips have ended up dying on the vine - at least in some parts of the country - due to [[MoralGuardians censorship]].

* {{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.]] 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/MortalKombat1 Mortal Kombat]]'' 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.
** It's rather telling that TV Tropes itself went for nearly a '''decade''' with only one page about {{Pinball}}. Administrivia/ThereIsNoSuchThingAsNotability, indeed.

[[folder:Professional Wrestling]]
* The territory days of Pro Wrestling used to define this trope. A wrestler who may have been huge in one area may have been relatively unknown to fans in another area. The WWF expansion and cable tv pretty much put an end to this however.
* For that matter, wrestling itself could be a victim of this. Wrestlers like Wrestling/JeffHardy or Wrestling/CMPunk are household names among wrestling fans, but have little or no mainstream recognition. Only a handful of wrestlers are known to non-wrestling fans (ie, Wrestling/HulkHogan, [[Wrestling/DwayneJohnson The Rock]], [[Wrestling/StoneColdSteveAustin Steve Austin]], etc)

* Radio is usually blamed for this phenomenon when it comes to music isolation.

* The UsefulNotes/UltimateFightingChampionship, AKA The [=UFC=] has dealt with this for problem for awhile, mainly due to the sport's previous violent image and detractors being unable (or unwilling) to get past it. Around the late 90's the [=UFC=] repackaged the sport as "Mixed Martial Arts" in an attempt to be taken seriously. It took a reality television show to gain wide acceptance. [=UFC=] has outsold boxing quite handily ever since '06, with '07 being the exception. Most of the sports broad casting community to this day refuses to except it as a legit sport. Some even went as far as to accuse it of being a poor (white) person's version of boxing, due to the [=UFC=]'s heavy young white male demographics compared to boxing. Today, while most people couldn't them you the names of the champions in each weight class, could at least tell you what the sport is. And with the [=UFC=]'s broadcasting deal with Creator/{{Fox}}, the days of the [=UFC=] being considered a niche sport are most likely over.
* [[XtremeKoolLetterz X-treme Sports]]
* College Basketball/Football's SWAC division.
** The MEAC too. Many of the schools in both divisions have traditions that are every bit as entrenched as the more well-known Southeastern Conference (SEC) schools. For example, each year a football team from a SWAC school meets a team from the MEAC in Indianapolis for the Circle City Classic. The festivities that lead up to the game draw more people to Central Indiana than any annual event besides the Indy 500, yet it's almost completely unknown to non African-Americans outside of the area.
* [[TheBeautifulGame Soccer]], of course. (at least [[AmericansHateTingle in North America]])
** That's a CyclicTrope. I think every generation we'll have a Pele or a David Beckham, but they'll be few and far between.
** But there are millions of soccer fans in America -- enough to post decent numbers for European soccer broadcasts on ESPN/FSC and keep UsefulNotes/MajorLeagueSoccer's numbers growing. However, unless it's WorldCup time, non-fans are unlikely to hear anything about soccer in America unless they very closely follow sports journalism.
** Note that the sitcom ''SportsNight'' had a scene where the characters -- who were professional American sports reporters! -- were challenging each other to simply ''name'' American soccer teams.
** The same is also true for Grid Iron/American Football. While there are teams and leagues across Europe (Britain hosts more than a few) the sport is largely ignored by the mainstream press except around the SuperBowl.
* Just like soccer, IceHockey has a huge following in the US (it is the 4th most popular sport after all), but mainstream coverage is sorely lacking.
** Again like soccer, it's a CyclicTrope. Wayne Gretzky and TheMightyDucks helped it out in the late 80s-early 90s but by the 2000s it faded out again, primarily due to the fumbling of the NHL's TV rights and having the league dropped from {{ESPN}} who now actively tries make its viewers believe the sport doesn't exist outside of the NCAA Division I championship[[note]]so much that their 2011 in memorium special didn't feature a single hockey player, [[MoralEventHorizon not even the Russian team killed tragically in a plane crash the previous fall]][[/note]]. Nowadays popularity is resurging again on the heels of new generation superstars like Sidney Crosby and Jonathan Toews, while the merger of Comcast and NBC-Universal saw the not-well-known Versus (the league's cable partner) become the Creator/{{NBC}} Sports Network, bringing a more recognizable brand and greater exposure. Unfortunately, NBCSN is still a distant 2nd to ESPN who now has more reason to put the sport down now that it's cozy with their only real competition.
** Ironically, ESPN was originally ''founded'' to broadcast Hartford Whalers games. Fans of the Carolina Hurricanes joke that it was that move and name change that ticked of ESPN about Hockey.
** The near-constant contract disputes and lockouts (to the point the ''fans'' joke about how often their seasons are at risk of cancellation) don't help.
* Lacrosse, along a similar vein. Oldest sport in the United States, older than the country itself, but played, almost exclusively from Virginia to New York. It's expanding rapidly, though, heralded as the fastest growing sport in the nation. It's still almost exclusively played by white, upper-middle class boys.
** Archer has helped awareness, and the writers seem to actually know that they're talking about, usually.
* Team handball is sort of a big deal in certain parts of Europe, but pretty much nobody ever gets to see it outside the [[OlympicGames Summer Olympics]]. When they do see it, however, they're impressed: TheSportsGuy Bill Simmons called it "[[http://www.grantland.com/story/_/id/8213663/handball-handball-handball a loony cross between hockey, basketball, lacrosse and Vince Vaughn's Dodgeball movie, only if it was created for people with ADD]]" and called for it to be brought to the US with a few minor tweaks.
** Even in countries where it has some popularity handball isn't that big a deal. For instance, in Brazil it's the most played sport in physical education class, and the female national team won the 2013 world championship - but the Brazilian tournament suffers from lack of exposure and financing.
* Until the late nineteenth century, sports were generally for the wealthy. Once athletic contests began to appeal to middle-class and working-class people, many of the more elitist sports (polo, regattas, fencing, etc.) fell into obscurity or semi-obscurity.
** This leads to the fact the IOC has to help the sports that aren't lucrative outside the OlympicGames, particularly during the recession.
* {{Cricket}}: Some estimates put it as the second most popular sport in the world after soccer (mainly due to its popularity in India), but it has never really caught on outside of the British Empire (with the possible exceptions of the Netherlands and the United Arab Emirates). In the USA, it barely rates a mention today, despite the fact that it was popular until around the time of the civil war, and in fact the first international cricket match was played between the USA and Canada in 1844. Anecdotal evidence even suggests that George Washington himself was a cricket enthusiast!
* As the name suggests, AustralianRulesFootball is mostly only popular in Australia - but did you know that it's a regional game there? Despite being the dominant code in 4 of Australia's 6 states, it still struggles to find a following in the other two (New South Wales and Queensland, the first and third most populous respectively), even with two teams based in each of those states in the national competition.
* Red Bull Crashed Ice, otherwise known as downhill ice cross, is very popular among Canadian extreme sports fans but unknown to most of the world.
* Welsh RugbyUnion referee Nigel Owens experienced this when travelling to the US. Going through airport security, he stated he was visiting for his work as a rugby referee, at which point the security personnel asked "what's rugby?".
* In the UK, any racket sport except tennis isn't generally noticed unless it's an Olympic sport in an Olympic year where we might have a medal chance. Squash, badminton and "real" tennis (the tennis you see at Wimbledon etc. is technically "lawn" tennis) barely get a mention.

[[folder:Tabletop Games]]
* To most people, Roleplaying Games other than video games is ''maybe'' something nerds did in highschool, and they may have heard the name ''TabletopGame/DungeonsAndDragons'', but the idea of it being a complex hobby mostly pursued by adults is unthinkable. "Board games" means Monopoly or Risk. Miniature wargaming can only be explained in terms of chess and toy soldiers.
* Similarly, most trading card games. Thousands of dollars in prizes are given away worldwide in some of the bigger tournaments (mostly TabletopGame/MagicTheGathering or TabletopGame/YuGiOh), but most people still consider them kids' games, and would only recognize a "professional" player if they cross over into something slightly more mainstream, like poker.
* And even with poker, only a few of the big names are well-known. And with the consequences of the poker boom, very few outside hardcore poker nuts could tell you who won the most recent World Series of Poker main event.

* Broadway actors often refer to themselves as "only famous for a couple of blocks". There are performers with astounding track records of roles and piles of awards who are absolute unknowns outside of New York City. Some have shaken this with success in film and television (such as Creator/KristinChenoweth, Creator/IdinaMenzel, Cheyenne Jackson, Creator/AaronTveit, Creator/LeaMichele, and Creator/JonathanGroff most recently), but going through a list of names of Tony winners will leave the average person scratching their head. From TheNewTens winners alone: Norbert Leo Butz? Sutton Foster? Audra [=McDonald=], who won a record-setting ''sixth'' acting Tony in 2014? This is ''somewhat'' justified. A successful Broadway show can launch a tour or sister production in another city -- most often London; the cities are Transatlantic siblings since it's easy to transfer a show from one to the other as there's no need to translate it into another language -- but the original leads usually don't leave New York. Most theater productions are not recorded for posterity, aside from cast albums for musicals, limiting the audience for these actors to devoted Broadway fans and those who come to New York and see them. This also applies to London's West End stars; just substitute Oliviers for Tonys -- Maria Friedman? Michael Ball? Even actors who've racked up honors on ''both'' sides of ThePond remain unknown to the masses -- Mark Rylance? Creator/DouglasHodge? Many of these performers do film and/or TV as well, but they're [[ClassicallyTrainedExtra usually relegated to supporting/minor roles or guest spots]], [[MoneyDearBoy albeit well-compensated ones]].
* Theatre in general, at least in North America, has become something of a niche ''medium'' in the mainstream media. The Tony Awards are still regarded as one of the big four awards shows, along with the Academy Awards (film), Emmy Awards (television), and Grammy Awards (music), but posts far smaller ratings than those three, owing to declining interest in what's making waves in New York City. Even entertainment-focused outlets tends to ignore live theatre unless someone famous in another medium decides to take a stab at Broadway. This, combined with a desire to bring in people who wouldn't see a show otherwise, leads to StuntCasting and/or limited-run shows that can accomodate a superstar's other commitments.

[[folder:Video Games]]
* Games in general, with rare exceptions such as PacMan and {{Mario}}.
* [[VideoGame/GrandTheftAuto GTA's]] radio stations are a great example of this. Some of the [=DJs=] even take shots at the other stations.
* PC-exclusive games might count as well.
* In general, various platforms tend to vary in popularity between countries and continents, especially when we're talking about the pre-Internet era when gamers from all over the world couldn't yet easily contact each other. For example, the UsefulNotes/ZXSpectrum is fondly remembered in Britain and Eastern Europe, but highly obscure in the United States.
** Consoles (not counting shady NES clones) were a niche market in Eastern Europe for the better part of the nineties. If you went to Poland about 1992 or so and asked a random gamer about ''Metroid'', ''Final Fantasy'' or ''Legend of Zelda'', he'd stare at you blankly, then ask what computer were they released on.
*** In some parts of America, Nintendo was a byword for "gaming console" throughout the 90s due to their enormous market share in the industry, especially due to its revival of the home console market after UsefulNotes/TheGreatVideoGameCrashOf1983. For a while, even dedicated gamers of a certain age would refer to most consoles as "a nintendo" (small "n" usually), even if it wasn't Nintendo made. Outside the US, Nintendo didn't have as much of a visible impact since gaming was largely PC driven.
*** In Russia a similar thing happened [[TheNewRussia in the 90s]]: in the absense of [=PCs=] and consoles, the [[http://en.wikipedia.org/wiki/Dendy_(console) NES clone "Dendy"]] became a generic name for any gaming console, and a lot of popular NES-era games were unknown because they were neither sold nor pirated.
* Speaking of which, how many people (including gamers) do you think have even heard of UsefulNotes/TheGreatVideoGameCrashOf1983? Let alone know that it nearly spelled the end for console gaming as a whole?
** Speaking of ''this'', at the time Video Game Crash was largely limited to and affected the North American industry; in Japan and many parts of Europe, video gaming continued to be quite popular.

* Virtually ''any'' webcomic, no matter how popular, will go almost entirely ignored by the mainstream media. This can be observed by their Wikipedia articles -- many webcomic articles have been deleted, while the few holdouts are widely padded with self-reference, and at best one or two third-party sources. The few that have ascended to mainstream notability include ''Webcomic/{{xkcd}}'', ''Webcomic/PennyArcade'', ''Webcomic/{{Megatokyo}}'', and ''Webcomic/CtrlAltDel''.
** ''Webcomic/AxeCop'' may have finally ascended into the mainstream in late 2013 with the arrival of its [[WesternAnimation/AxeCop cartoon adaptation]] on Creator/{{Fox}}.

[[folder:Western Animation]]
* As strange as it may sound today, Creator/{{Disney}} fell victim to this trope for a very long time within the United States. While the studio was always massively popular from UsefulNotes/{{Chicago}} to the west coast (''especially'' in UsefulNotes/{{California}}), everywhere east of Chicago its reception was a bit more lukewarm. Film critics considered the studio's output kitschy at best, and people used the term "Mickey Mouse" to refer to something poorly constructed or put together. The main reason for the Disney attractions at the 1964 New York World's Fair was for WaltDisney to prove to his studio that there was a market for Disney on the east coast, an experiment which proved successful and ultimately culminated in the opening of Disney World in central Florida in 1971; but even then, they didn't really gain the reputation they have today until [[TheRenaissanceAgeOfAnimation the late 1980s/early 1990s]]. This was pretty much exemplified in the mid 1980s when UsefulNotes/NewYork native Michael Eisner became CEO of the studio, and sheepishly admitted to the California-based board of directors that he had never actually seen a Disney film before taking the job.
* As refrenced in Anime above, many VoiceActors are unknown to the mainstream unless they've done some sort of live-action acting. It's a rarity that a voice actor is known for just their voice acting; even MelBlanc was known mostly for being on the JackBenny Program before the popularity of LooneyTunes shot through the roof.
* ''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.
** 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 [[UnfortunateImplications most of the fanbase is just weird]].

* Most major sci-fi/anime/comics conventions (except for San Diego [=ComicCon=], which has become very mainstream and a crucial stop on many promotional tours) are not nearly as well known outside of various geek communities (and the locals of the particular city where the con is usually held). For instance, Dragon*Con is well known to geeks and [[{{Atlanta}} Atlantans]], but not very many else.
** [=ComicCon=] itself used to be a case of this up until the mid 00s. Now judging from the sheer amounts of game (and movie) related announcements, one would think the event is now {{E3}} 2.0.
** Similar regarding furry cons and meets - there are multiple ones in most major countries, to the point where people can make a lifestyle out of travelling to different ones when they are on. It's also a great financial boost for the local economies when they are held (often to the pleasant surprise of hotel staff). Yet, the fandom has sprung up largely due to the internet and doesn't widely advertise itself. Generally speaking furries don't want the media covering them because it's historically presented the fandom as consisting solely of fetishists (who are a vocal minority, but a minority nonetheless).
* Quite a few white people appear to be unaware of the ButNotTooBlack controversy. Ironic since every daytime talk show known to man from Ricki Lake to Jenny Jones to Tyra Banks has covered this issue.
** Inversely a lot of black people think this issue is only seen within their community, but it's very prominent in Asian and Hispanic communities as well.
* Back in the times of the ColdWar, it was possible to receive [[TheBonnRepublic West German]] TV-programs in most places of EastGermany - except in the area of the Dresden Basin. Because of this lack of information regarding Western news coverage and of course also Western pop culture, it was accordingly called the "[[FanNickname Valley of the Clueless]]".
** In turn, few West Germans bothered to consume East German pop culture, which now can cause Pop Culture Isolation in [[TheBerlinRepublic re-unified Germany]].
* TONS of internet models and celebrities that are made famous through the net are more or less obscure in pure mainstream media. Basically any model or obscure female actress that's ever appeared on or in Stuff magazine, Maxim, or FHM. Sure people on the net are familiar. But to the general public they might as well be nobodies
** Their attractiveness is what help them get noticed in the first place despite being D-Listers. Case in point Jaime King pre-SinCity. You'd be hard pressed to find someone in the mainstream who knew who she was. But Maxim magazine and people on the internet did. Interestingly enough she hasn't done anything mainstream since. Likewise with Emmanuelle Vaugier prior to {{CSINY}}.
*** Some of these actors/models/actresses careers can be chalked up to a combination of this trope, HeyItsThatGuy, CriticalDissonance, HypeBacklash, and ICouldaBeenAContender all rolled up into one. Usually in that order too. (see also HollywoodHypeMachine)
** Cindy Margolis probably being the UrExample. From the way the internet treated her you'd thought she was a break out star or something.
** Then there's Tila "Tequila" Nguyen.
** Amber Rose as well is gradually heading down this road thanks to photoblogs. Dating KanyeWest probably helped.
* Music video models are the same way obviously. Lots of rock fans know who Bobbie Brown, and Tawny Kitaen are. While urban music video watchers are probably only vaguely familiar if that. Same goes for models that appear in urban music video like Esther Baxter, Melyssa Ford, and Summer Walker etc...Even in that context there's not a lot of people who know them outside certain internet circles (I.E. HipHop ImageBoards, where they're well known and popular). But bring their names up in certain mainstream social circles and you would get blank stares.
* Unfortunately ''Black History Month'' has become this instead of being seen as part of American history too. Especially ''Native American History Month'' which is November.
* Most popular porn stars who aren't Jenna Jameson or Ron Jeremy... although some might get some mainstream attention primarily from news outlets because of some type of controversy surrounding said performers or the industry itself, like the Belladonna and Sasha Grey Primetime Live/The Insider news interviews (respectively) for example.
** Interestingly enough even the most obscure porn star can have tens of ''thousands'' of twitter followers. Of course, they do say that TheInternetIsForPorn...
* This trope with a dusting of racism might be the cause of all of the numerous segregated proms in the south, which have offended black teens and other minority teenagers.
** Sorority pledges are the same way. There's usually flame wars on and off the net over whether people are "forcing" groups to accept them (usually saying [[UnfortunateImplications it makes people secretly accept them less]]), while another group claims why would you wanna be apart of said racist group anyway. Or they'll accuse the group of wanting to be white, if there was likely a black sorority they could have joined.
* A lot of cynics think this is why interracial relationships/marriages can't work unless they're from the same socio-economic background and are fully assimilated into mainstream American culture (or whatever culture their significant other is from).
** Which is sad, as they could see the very same circumstances as an opportunity to learn from each other and widen their horizon.
* E! network host Sal Masekela noted in an interview with JayZ that entertainment news media and tabloids generally don't cover black celebrities. Quite frankly, black celebs should probably see that as a blessing in disguise.
** Unfortunately, on the flip side there's urban gossip mags and blogs to compensate for this, especially during the past ten years.
* The aforementioned magazines like ''FHM'', ''Maxim'', ''Stuff'', and so on run on this trope. It's a pretty safe bet that most people outside the internet have never heard of half of the listed people in Maxim's Hot 100. Just mention the name Gemma Atkinson[[note]]No, not the chick from ''Film/QuantumOfSolace''[[/note]] to some random American and they wouldn't know who the hell you're talking about.
** These mags have black counterparts as well like ''King'', ''SMOOTH'', and ''Black Men Magazine''. And most of the models within are hardly known outside of HipHop message boards.
** {{Playboy}} Playmates fall into this category as well. Although some Playmates have crossed over into the mainstream (PamelaAnderson, JennyMcCarthy, Anna Nicole Smith), others are virtually unknown to those who aren't avid Playboy readers.
* If a country has regions that speak different languages they tend to develop their own cultures based on these languages.
** In Canada, Quebec has many musicians, actors, and comedians that are unknown in the rest of Canada unless they also do English-language work.
* Linux powers sites like Google (as well as Android) and hardcore geeks run it on their desktops, but among people who even know what an operating system is in the first place, they're more likely to be familiar with Windows or Mac OS X.
* If you walk into a store that caters to wargamers, a store that caters to model train hobbyists, and a general crafts store, you will see very similar merchandise on the shelves, but the staff are likely to be completely unaware of their "competitors".
** Similarly, stores where wargaming is king vs. stores where roleplaying and/or [=TCGs=] are king vs. stores where video gaming is king.
* 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. [[MemeticMutation Memes]] 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."
** In fact, 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.
* This is pretty common with universities in the United States, For example, the University of Michigan and Michigan State University are the two top universities in Michigan and both attract huge numbers of students from all over the state. However, go to a more distant state like New Jersey, and you'll find plenty of Wolverines but hardly any Spartans.
** With the exceptions of Ivy League schools and certain other prestigious colleges like MIT and Stanford, most national universities are known almost exclusively for their football and/or men's basketball teams.
* Youtube celebrities are a great case of this. Millions of subscribers, but the odds of your average person knowing one of them isn't very good. The reactions on the Youtube ''WebVideo/{{React}}'' channel sometimes hints that most of them [[SmallNameBigEgo don't actually get this]].
* Website/FourChan, while a cornerstone of internet culture is very obscure outside it. Its main claim to fame outside of it is "The Fappening."
