* The theatrical short cartoon was killed by ''[[https://en.wikipedia.org/wiki/United_States_v._Paramount_Pictures,_Inc. United States v. Paramount Pictures, Inc.]]'', a Supreme Court case which forced major studios to get rid of their proprietary theater chains on the grounds that they were monopolistic. While cartoons were popular, they were unprofitable because of their short length; the only reason short subjects could be produced was the fact that distribution costs were extremely small for major studios, which imposed their product on theater owners.

While cartoons were popular, they were unprofitable because of their short length (the only reason short subjects could be produced was the fact distribution costs were extremely small for major studios, which imposed their product on theater owners).

* The debut of the Sony Walkman in 1979 quickly killed off the 8-track tape as the premier portable music format. Compact cassettes had already been making a steady climb as a viable alternative to both vinyl records and 8-tracks thanks to advancing hi-fi technology surrounding them and cassettes being able to more closely follow the tracklists of their vinyl counterparts (compared to 8-tracks, which often had to edit albums to fit the restrictions of the four-program tapes), but the Walkman rapidly solidified the ousting of 8-tracks by introducing an even higher degree of portability, making it possible to listen to music anywhere at any time (whereas 8-tracks could only be played at home and in car stereos).

* Similar to how the cassette killed 8-tracks, the cassette was itself done in by a combined death blow of portable CD players with anti-skip and affordable recordable CD formats in the second half of TheNineties. While portable CD players existed before, they would skip when even slightly jostled, making them impractical in actual mobile use. Music fans would either have to make a cassette copy or purchase a prerecorded cassette if it was one of the increasingly common longer albums to listen to music outside the home. Anti-skip made it possible to actually listen to [=CDs=] on the go at the expense of battery life. This killed off the cassette Walkman. CD players also became standard equipment in new cars around the same time, and cassette/cigarette lighter adapters made it easy to retrofit existing car stereo systems with portable players. The advent of recordable [=CDs=] also eliminated another niche for the cassette, and later UsefulNotes/{{MP3}} players would do away with physical media altogether. Cassettes quickly disappeared from developed markets, though they would have a revival similar to that of vinyl records in the 21st century.

Every era is defined by trends. They tend to vary in period of popularity and quality, but they don't last forever. Sometimes, it may be because of changes in society or [[TechnologyMarchesOn technology marching on]], causing it to become a DiscreditedTrope. There may also be times when any works making use of a particular trend bomb on a regular basis, leading to creators abandoning said trend.

Compare TheRedStapler for when a work of fiction inspires a trend in real life, and BabyNameTrendKiller for when a work makes a name fall out of favour.

* 1986 saw the release of both ''WesternAnimation/RamboTheForceOfFreedom'' (based on 1982's ''Film/RamboFirstBlood'' and 1985's ''Film/RamboFirstBloodPartII'') and ''WesternAnimation/TheRealGhostbusters'' (based on ''Film/Ghostbusters1984'') along with accompanying toylines. While Rambo was in essence a ripoff of ''WesternAnimation/GIJoeARealAmericanHero'', it was still a modest success. Combined with the runaway success of ''The Real Ghostbusters'', this led to a number of children's cartoons and toylines based on non-child-friendly properties. 1989 saw the release of ''WesternAnimation/{{Robocop}}'' (based on 1987's ''Film/{{Robocop}}'') and ''WesternAnimation/PoliceAcademy'' (based on 1987's LighterAndSofter ''Film/PoliceAcademy4CitizensOnPatrol'' rather than the R-rated original). 1991 saw the release of ''WesternAnimation/ToxicCrusaders'' (based on 1984's ''Film/TheToxicAvenger'', most assuredly not suitable for kids). 1991/1992 also saw kid-friendly toylines released for ''Film/Terminator2JudgmentDay'' and ''Film/{{Aliens}}'' despite both properties most assuredly not being kid-friendly (though a cartoon was planned for ''Aliens'', the deal fell through and the toys simply released in the toyline without an accompanying cartoon). ''The Real Ghostbusters'' puttered along until 1991 (where a combination of ExecutiveMeddling and resulting LighterAndSofter tone eventually killed it), putting an end to the trend of marketing R-rated properties to children.

* The relative commercial failure of Music/FleetwoodMac's ''Music/{{Tusk}}'' struck a major blow to the popularity of double albums in popular music that would span the next thirty years. The format had long existed on shaky ground due to its high production costs, but ''Tusk'' underselling compared to the blockbuster sales of ''Music/{{Rumours}}'' made labels and artists alike far more reluctant to release double albums except out of necessity. When the rise of [=CDs=] made longer albums fashionable again, the LP versions would either pare down the material or pack the grooves closer to avoid using more than one disc, and double-CD releases are still rare outside of {{live album}}s and compilations. Double-LP albums would only become popular again with the Vinyl Revival, which made it easier to profit off of a MultiDiscWork on vinyl (which was often necessary due to many albums still featuring CD-centric runtimes).

* The fall of animated TV shows made to promote celebrities, the Children's Television Act of 1990, and changing tastes would eventually deliver the ''coup de grâce'' for the SaturdayMorningCartoon block. The rise of kid-oriented channels on cable only accelerated this trend by the 2000s. After the Nick on CBS block ended in 2006, Saturday morning cartoons on network television became strictly edutainment fodder with the exception of FOX's 4KidsTV and the children's blocks on The CW before dying out entirely in 2016 in favor of cheap-to-produce live-action edutainment shows that exploit loopholes to allow for product placement and more advertising than would otherwise be allowed.

* ''VideoGame/{{Skylanders}}'' and the entire ToysToLifeGame genre was killed due to market oversaturation, largely in part to Creator/{{Disney}} attempting to hijack the craze with ''VideoGame/DisneyInfinity'', which saw a new version every year that added some new content but wasn't compatible with previous story packs. Two series that were both very MerchandiseDriven put a large amount of strain on the idea, which wasn't helped when Creator/{{Lego}} jumped on the bandwagon with ''VideoGame/LegoDimensions'', now draining even more of consumer satisfaction and money. Creator/{{Activision}} at this point began to try to prioritise new games, in order to not get drowned out by Disney and Lego. In Q3 of 2015 alone, ''3'' different major Toys To Life games were hitting the markets. That many different games largely made consumers realise the money spent wasn't worth it for cash-grab games, and thus the market for Toys To Life began to die, and by 2017, all three game franchises had been killed off due to disappointing revenue. The [[https://comicbook.com/gaming/news/ubisoft-talks-lessons-learned-from-the-failure-of-starlink/ fail]][[https://www.linkcablegaming.com/the-inevitable-demise-of-starlink-battle-for-atlas/#:~:text=While%20most%20of%20the%20industry,live%20up%20to%20their%20expectations ure]] of ''VideoGame/StarlinkBattleForAtlas'' that same year served as proof the market had been oversaturated, and all four game franchises haven't had a new release again.

* Thanks to the runaway success of ''WesternAnimation/TeenageMutantNinjaTurtles1987'', it was followed by ''ComicBook/BuckyOHareAndTheToadWars'' (1991), ''WesternAnimation/ToxicCrusaders'' (1991), ''WesternAnimation/WildWestCOWBoysOfMooMesa'' (1992), ''WesternAnimation/BikerMiceFromMars'' (1993), ''WesternAnimation/StreetSharks'' (1994), and ''WesternAnimation/ExtremeDinosaurs'' (1997) all starring a team of mutants or FunnyAnimal heroes and accompanying [[MerchandiseDriven toylines]]. The original TMNT cartoon was such a successful LongRunner (lasting till 1996!) that after its cancellation, the concept of a FunnyAnimal or UpliftedAnimal hero team mostly went with it.

* ''Film/XXXStateOfTheUnion'' in 2005 killed the early-to-mid-2000s trend of fast, modern, teen-oriented action films centered on extreme sports. While the ''Fast'' film series, which pioneered the trend, is still going strong today, later installments have focused more on straightforward action and car chases as opposed to the earlier, more extreme sports-centered installments.

* The critical and commercial failure of ''WesternAnimation/HomeOnTheRange'' was the final nail in the coffin for Hollywood-produced traditionally animated films, which were already experiencing diminishing returns as audiences gravitated toward CGI films. Nowadays, the only traditionally animated movies being produced for the big screen are based on TV Shows and even ''that'' is changing (eg, ''WesternAnimation/{{Scoob}}'' and ''WesternAnimation/TheSpongeBobMovieSpongeOnTheRun'' are CGI movies based on traditionally animated shows).

[[folder:Film -- Live Action]]

* Adult-geared sex comedies remained wildly popular for most of the 2000s, but stricter MPAA guidelines post-2010 made it even harder to sneak more intense material. Subsequent attempts at reviving the trend, like ''Film/ProjectX'', have been widely reviled, while 2011's ''Film/BadTeacher'' and the sequels to 2009's ''Film/TheHangover'' were subject to greater scrutiny than previous works. While 2012's ''Film/{{Ted}}'' and 2014's ''Film/{{Neighbors}}'' gave adult comedy a shot in the arm, its reputation was affected in 2016 by ''Film/DirtyGrandpa''. It did well at the box office, but received such an overwhelmingly negative response that subsequent attempts at adult comedy in the same year either became financial disappointments or outright flops. The slipping box-office numbers (aside from lack of success outside the English-speaking world) largely reduced comedy films to direct-to-video/streaming material with the odd limited theatrical release.

* ''Film/BatmanAndRobin'' killed the trend of superhero movies with a lighthearted, borderline comical tone. The success of ''Film/{{Blade}}'', ''Film/XMen1'', and ''Film/SpiderMan1'' convinced studios that more grounded and realistic takes on comic book characters was the way forward for the genre. It would not be till 2014's ''Film/GuardiansOfTheGalaxy'' (and the failures of many DarkerAndEdgier comic book movies) that such a tone would be deemed acceptable again.

* The advent of digital video helped diminish the need and demand for sitcoms to be shot on video tape. During the 1970s and even on through the '90s, a number of television programs, particularly sitcoms, were videoed as opposed to being shot on 35mm film. Videotape was far cheaper than film, and its processing and post-production costs were far lower. The tradeoff was that quality of videotape was inferior to film and most of the series shot on videotape have not fared well in syndication, especially since the early 1990s. While some overcame the "stigma" of being shot on video (''Series/AllInTheFamily'', ''Series/TheCosbyShow'' and ''Series/ThreesCompany'' being among the most prominent examples of this) the majority of such programs have either lost ground or are simply no longer aired. On the other hand, filmed programs (''Series/{{MASH}}'', ''Series/{{Cheers}}'', ''Series/{{Friends}}'', etc.) remain quite popular not only due to the talent of their respective casts but also in part due to the quality of their production values. It's much easier ("easier" being a relative term) to "clean up" the filmed footage of older programs than it is a video. Ultimately, quality and cost were the decision-makers in the past when shooting television productions in either film or using video.

* 1986 saw the release of both ''WesternAnimation/RamboTheForceOfFreedom'' (based on 1982's ''Film/RamboFirstBlood'' and 1985's ''Film/RamboFirstBloodPartII'') and ''WesternAnimation/TheRealGhostbusters'' (based on ''Film/Ghostbusters1984'') along with accompanying toylines. While Rambo was in essence a ripoff of ''WesternAnimation/GIJoeARealAmericanHero'', it was still a modest success. Combined with the runaway success of ''The Real Ghostbusters'', this led to a number of children's cartoons and toylines based off of non-child friendly properties. 1989 saw the release of ''WesternAnimation/{{Robocop}}'' (based on 1987's ''Film/{{Robocop}}'') and ''WesternAnimation/PoliceAcademy'' (based on 1987's LighterAndSofter ''Film/PoliceAcademy4CitizensOnPatrol'' rather than the R-rated original). 1991 saw the release of ''WesternAnimation/ToxicCrusaders'' (based on 1984's ''Film/TheToxicAvenger'', most assuredly not suitable for kids). 1991/1992 also saw kid-friendly toylines released for ''Film/Terminator2JudgmentDay'' and ''Film/{{Aliens}}'' despite both properties most assuredly not being kid-friendly (though a cartoon was planned for ''Aliens'', the deal fell through and the toys simply released in the toyline without an accompanying cartoon).

* The trend of adapting young adult dystopian novels ended when the third ''Film/{{Divergent}}'' film -- ''Allegiant'' -- performed so poorly at the box office that the following movie, ''Ascendant'', was retooled as a TV movie before being cancelled entirely. Attempts to rectify this haven't had much success, with film adaptations of ''Film/TheDarkestMinds'', ''Film/ArtemisFowl'', and ''Film/ChaosWalking2021'' bombing and receiving poor reviews. While ''Film/MazeRunnerTheDeathCure'' (2018) fared much better, it was part of a pre-established franchise rather than an attempt at adapting new material, and even that series was experiencing diminishing returns.
* ''Allegiant'' also killed the trend of [[DividedForAdaptation splitting the final book]] into [[TheFilmOfTheBook two movies]] started by ''Film/HarryPotterAndTheDeathlyHallows'' in 2010/2011, with the ''Literature/{{Twilight}}'' and ''Literature/TheHungerGames'' adaptations all following suit and ''Film/TheHobbit'' adaptation being extended to three films (based on one book). ''Divergent'' series went down the same path, intending to divide ''Allegiant'' into ''Allegiant'' (2016) and ''Ascendant'' (2017). Unfortunately, ''Allegiant'' performed poorly at the box office, which resulted in ''Ascendant'' never being made, and ''[[Film/TheMazeRunner The Maze Runner]]'''s third film, ''[[Film/MazeRunnerTheDeathCure The Death Cure]]'' (2018) not being split. Even ''The Avengers'' renamed ''Infinity War Part 2'' to ''Endgame'', while ''Justice League Part 2'' was put on the back burner before the first movie even came out.

* The critical and commercial failure of the film adaptaion of ''Series/GeorgeAndMildred'' in 1980 ended the trend of adapting {{Britcom}}s into feature-length films in the 1970s, with it not being until ''Film/{{Bean}}'' in 1997 that the idea was even revisited.

This is one level below GenreKiller, though the reasons why both occur are similar - Genre refers to a category, while a trend refers to an element or trope. For example, Action is a genre. ActionHeroine is an element in Action films.

* ''Film/{{Airplane}}'' was not only a GenreKiller for the DisasterMovie -- it also [[CondemnedByHistory killed the aerial subgenre retroactively]], as the airliner-in-peril/stewardess-lands-the-plane trope of the previous Airport series was destroyed, and all the drama with it.

* The failure of ''Film/{{Watchmen}}'' killed any attempts at R-Rated graphic novel-based movies for nearly a decade. It wasn't until the success of ''Film/{{Deadpool}}'' in 2016 that they were considered again.
* ''Franchise/ChildsPlay'' helped kill off the fad that started with Cabbage Patch dolls and ended with the "My Buddy" dolls. Since those dolls looked a lot like Chucky - the BigBad of the films -- [[https://nightmarenostalgia.com/2021/08/30/the-downfall-of-the-my-buddy-doll-thanks-to-a-good-guy-named-chucky/ the line of dolls were effectively scrapped]].

* In the 2000s, most romance-themed movies could be split into two camps: (A) Pandering rom-coms occupied by the likes of Creator/JenniferAniston, Creator/KatherineHeigl, Creator/CameronDiaz, and Creator/ReeseWitherspoon playing sassy characters, and (B) weepy, melodramatic movies that copied ''Film/TheNotebook''. ''How Do You Know'' in 2010 and ''Film/{{Bridesmaids}}'' in 2011 killed the first type, the former due to going over-budget and bombing, and the latter by featuring a female protagonist thoroughly independent from the romantic male lead, while successfully adapting the Judd Apatow style of raunchy humor and character-focused writing. It did not help matters that a new generation of young actresses had no interest in playing either "ditzy girls" or killjoys and the sexist undertones of rom-coms were emphasized, even by Aniston and particularly Heigl themselves, who had sworn off many of their movies.

* ''Film/XXXStateOfTheUnion'' in 2005 killed the early-mid 2000s trend of fast, modern, teen-oriented action films centered on extreme sports. While the Fast film series, which pioneered the trend, is still going strong today, later installments have focused more on straightforward action and car chases as opposed to the earlier, more extreme sports-centered installments.

* ''WesternAnimation/ACharlieBrownChristmas'': Aluminum Christmas trees were a popular trend in the late-'50s/early-'60s, but its depiction here as a symbol of soulless holiday commercialism is credited with killing its popularity. It even inspired [[AluminumChristmasTrees a trope on this site]], which defines something that sounds fictional, but actually isn't.

* The fall of animated TV shows made to promote celebrities, the Children's Television Act of 1990, and changing tastes would eventually deliver the ''coup de grâce'' for the Saturda MorningCartoon block. The rise of kid-oriented channels on cable only accelerated this trend by the 2000s. After the Nick on CBS block ended in 2006, Saturday morning cartoons on network television became strictly edutainment fodder with the exception of FOX's 4KidsTV and the children's blocks on The CW before dying out entirely in 2016 in favor of cheap-to-produce live-action edutainment shows that exploit loopholes to allow for product placement and more advertising than would otherwise be allowed.

* The monster successes of shows like ''WesternAnimation/PAWPatrol'' and ''WesternAnimation/DocMcStuffins'' has mostly ended the use of Fake Interactivity in preschool shows that ''WesternAnimation/BluesClues'' made popular. Now, most preschool-aimed content tries to teach kids lessons without faking interactivity. A research study done by Disney in 2010 provides further insight into why this is the case. Before the Disney Junior block was conceived, the company surveyed parents and asked them what they wanted to see in the shows their kids watched. Most parents wanted their kids to watch stories that would make them happy and that they could tell back to their parents, a change most likely resulting from the rise of tablet and smartphone apps teaching preschool concepts. In comparison, when Disney conducted the same survey five years prior, parents wanted their children to learn educational concepts from these shows.

* The failure of ''WesternAnimation/MarsNeedsMoms'' resulted in the shut-down of Creator/RobertZemeckis' Image Movers Digital studio and with it, the death of full-form motion-capture animation. However, SerkisFolk mo-cap animation for live-action features is still very much alive.
