[[caption-width-right:320:And then they had to reboot it ''[[Film/ManOfSteel again]]'', seven years later.]]

->''"I think we might have killed the franchise."''
-->-- '''Creator/GeorgeClooney''' on ''Film/BatmanAndRobin'' (and [[Film/BatmanBegins until 2005]], he was right)

Sometimes a sequel [[{{Sequelitis}} sucks]]. Sometimes it sucks, but leaves the possibility open that the [[SurprisinglyImprovedSequel followup will be better]] and that this is just [[DorkAge a blip in the quality]] of the franchise. Then sometimes it sucks ''so much'' that it kills the franchise stone dead, destroying the producers'/publishers' hopes for further sequels. In the most extreme cases, it can even [[CreatorKiller take the producer/publisher down with it]]. Or even the [[GenreKiller entire genre itself]].

Occasionally a few Franchise Killers over too short a period (or one ''really'' bad one) [[GenreKiller can put a whole genre out of favour for a while]]. Even the executives could tell when it's time to stop [[FollowTheLeader following the leader]].

Note that sometimes the franchise turns out to be NotQuiteDead, and can be salvaged with a ContinuityReboot. If the franchise experiences what ''should'' have been a Franchise Killer but carries on regardless, it's a FranchiseZombie. Occasionally it's a StillbornFranchise, an all-new product for which plans for sequels were made and then scrapped when it was discovered that the product was crap, or so [[HypeBacklash hyped up]] that [[ThisIsGoingToBeHuge the creators have unrealistic expectations of its success]]. Or it just didn't profit enough, even though it was a CultClassic.

For many VideoGame companies, shipping a Franchise Killer is also a CreatorKiller, either through bankruptcy, no-one wanting to forward them the funding to continue making games, or in the modern world of mega-corporations owning every studio as a subsidiary of the larger corporation, the executives in charge of the conglomerate deciding to shut the studio having wrung the last vestiges of profit out of the intellectual property the studio was bought for, or using them as scapegoats for poor performance financially speaking. Or in some cases, actual poor performance as a studio.

Compare TorchTheFranchiseAndRun, where a writer is deliberately trying to kill a franchise by making such a big mess of it that no one can continue it without using {{Prequel}}s, {{Retcon}}s or just [[ContinuityReboot rebooting]] the whole thing. See also ToughActToFollow, where one work in a series is seen as so good that subsequent installments are seen as not worth the time and money.

[[folder: Anime and Manga]]
* The anime ''Anime/DigimonFrontier'', which followed the [[ToughActToFollow popular]] ''Anime/DigimonTamers'', is often blamed by Western fans for killing the anime franchise for three years. However, the harsh truth is that while ''Tamers'' was a critical darling for older fans, it was '''not''' popular amongst Digimon's target demographic of young children. The derided HenshinHero gimmick of ''Frontier'' was a hasty attempt to win back the viewers (and merchandise sales) that ''Tamers'' had lost, a patch-job that ultimately failed to reverse the decline.

* The ''Gundam'' franchise had been on shaky grounds for several years, in part due to low ratings, but also the conflicted leadership of Creator/{{Sunrise}}, the studio behind the series. ''[[Anime/MobileSuitVictoryGundam Victory Gundam]]'', the last televised installment to take place in the Universal Century continuity, was under massive pressure from main sponsor Bandai, resulting in a reshuffling of early episodes to showcase the titular mecha of the show earlier, and the addition of several {{toyetic}} mechs later in the show's run. Yet the show did not prove to have satisfactory sales, and combined with Sunrise being bought out by Bandai, was replaced with the extremely different AlternateUniverse ''[[Anime/MobileFighterGGundam G Gundam]]'', which featured many, many Gundams, and has an extensive toyline. The ratings for the series did not improve, but the toy sales went up, setting a precedent for future TV shows to always be set in alternate universes. The Universal Century still lives on though, quite successfully at that, with [[OriginalVideoAnimation OVAs]] like ''[[Anime/MobileSuitGundamThe08thMSTeam The 08th MS Team]]'' and ''[[Anime/MobileSuitGundamUnicorn Gundam Unicorn]]'' setting sales records.
* ''[[Anime/AfterWarGundamX Gundam X]]'''s ratings almost killed the franchise, presumably due to there having been ''Gundam'' on screen every week for 4 years at that point. The series disappeared off TV for 3 years until the similarly unsuccessful ''Anime/TurnAGundam'' (although the series continued on Video and Film with ''The 08th MS Team'' and ''[[Anime/MobileSuitGundamWingEndlessWaltz Endless Waltz]]''). It was not until the massively successful ''[[Anime/MobileSuitGundamSEED Gundam SEED]]'' that the series was revitalized. ''Gundam X'' is one of only two Gundam TV series to be cut short of a full two-season run. The first? The original ''Anime/MobileSuitGundam''; it's easy to forget given what a massive franchise it has become when the original installment had poor ratings.
* In America, it was ''Gundam SEED'' that killed the franchise. In this case, one can blame [[{{Bowdlerise}} the heavy edits Toonami made.]] Desperate to air the show in a daytime slot, Creator/CartoonNetwork's cuts turned the show into a complete mess, most notably by forcing the series to NeverSayDie, drastically changing battle scenes, and featuring the use of [[FamilyFriendlyFirearms the notorious "Disco Guns."]] In spite of the show's serious nature, the bizarre and drastic edits caused the fanbase to not take the show seriously and it showed in the ratings. By episode 26, the series could only be seen at [[FridayNightDeathSlot Friday at midnight]]. After its shaky run, ''Gundam'' would go back to being only seen on DVD until [[Creator/{{Syfy}} Sci Fi Channel]] revived the franchise by airing ''Anime/MobileSuitGundam00'', and Toonami didn't air ANY new Gundam series until 2016, when they got ''Anime/MobileSuitGundamIronBloodedOrphans''.[[note]]While the network did air an episode of ''Anime/MobileSuitGundamWing'' as part of its April Fools broadcast in 2012, SEED was the last full TV series the network aired until IBO[[/note]].
** ''[[Anime/MobileSuitGundamSEEDDestiny Gundam SEED Destiny]]'' managed to kill Sunrise's official English-language Gundam message board (the centerpiece of the English language website), despite not even airing outside of Japan until years later (and even then it only aired in Canada). Numerous American fans were watching fansubs of the ''SEED Destiny'' episodes within days of their air dates (or even sooner in the case of American fans who speak Japanese, which in the Gundam fandom turns out to be a surprisingly large number) and thus it was the biggest topic of discussion the message board (without, of course, the fansub aspect being mentioned; it was the ''official'' message board after all). The [[BrokenBase extremely divided fan opinion]] about ''SEED Destiny'' is well known, but the disagreements were kept mostly civil. And then the final episode aired, and the opinions voiced on the message board were almost universally (and often quite vehemently) negative, even among those who'd generally approved of the way the story had gone in the second half. Shortly afterward (and without advance notice), Sunrise pulled the plug on the message board entirely, leaving [=GundamOfficial.com=] little more than an empty shell that to this day no longer gets updated (when ''Gundam 00'' aired on Sci Fi, it was given its own separate English-language website).[[note]]Particularly tragic in that [[BigNameFan Mark Simmons]]' excellent fansite "Gundam Project" was shut down after he was hired by Sunrise to run [=GundamOfficial.com=].[[/note]] In fact, given that the ''SEED Destiny'' finale aired in Japan less than six months after the ''SEED'' finale aired in North America (many Gundam fans, especially those newly-introduced to the franchise, went straight from watching ''SEED'' in English to watching fansubs of ''SEED Destiny''), this incident may have even played a role in Gundam's long disappearance from American TV broadcasts, with Sunrise drawing the (ridiculously false) conclusion that negative reaction to the ''SEED Destiny'' finale meant that Americans just didn't like ''Gundam''.
** Seedís success once even started talks that the Cosmic Era timeline could become the new Universal Century in terms of production of sequels and side-stories. However, [[TroubledProduction production troubles]] involving Destiny and the subsequent release and success of non-CE series ''[[Anime/MobileSuitGundam00 Gundam 00]]'' have since dashed those hopes. A movie meant to tie up the Cosmic Era timeline has been stuck in DevelopmentHell for years (due to the declining health and in 2016, [[AuthorExistenceFailure eventual death]] of head writer Chiaki Morosawa, [[CreatorCouple the wife of]] ''SEED'' and ''SEED Destiny'' director Mitsuo Fukuda), and its fate is uncertain.
* There was Creator/{{Toonami}}'s broadcast of the original ''Mobile Suit Gundam'', a series that was made in 1979 and had yet to receive any sort of modernization. It didn't help that ''Mobile Suit Gundam'' was following on from ''Anime/MobileSuitGundamWing'', a series that (at the time) was one of the most modern ''Gundam'' series (made in the 90s and all). The result? ''Mobile Suit Gundam'' never finished its initial run, with Cartoon Network using 9/11 as an excuse to pull the show a good chunk of episodes from the end. That being said however, it was briefly revisited during a New Year's Eve special, in which series belonging to favorite Toonami block villains (as voted upon by fans) were broadcast on the Midnight Run. Surprisingly, [[RedBaron Char Aznable]] was voted near the top slot (beating out ComicBook/TheJoker as he appeared in ''WesternAnimation/BatmanTheAnimatedSeries'', no less), and as a result Toonami ran the final episode of the series in his honor.
* In Japan and amongst the world, the almost-franchise killer was ''Anime/MobileSuitGundamAGE''. Stylistically, it was attacked for appearing to be a "kiddie" version of Gundam, but the series was actually one of the darker stories in Gundam canon, with the series being introduced during a violent invasion attack, featuring a VillainProtagonist, and the first major antagonist being a ''[[EnfanteTerrible seven-year-old]]''. During much of the series, it was criticized as being the ClicheStorm of ''Gundam'', drawing forth all the various tropes and themes that were utilized in the other installments to fill out the story. It would have killed off the franchise if not for the release of ''Anime/GundamBuildFighters'', which made up for the countless flak it received. The main point of contention towards ''AGE'' was the Kio/Three Generation Arc. Up until that point, the series had actually been doing good, especially with its more likable second protagonist Asemu Asuno. When Kio took over, things looked like it was going to head in that same direction, but when Kio took [[Anime/MobileSuitGundamSEED Kira Yamato's]] famed pacifism to [[UpToEleven new levels]] that infuriated fans, ''that'' is when ''AGE''[='=]s quality and popularity took a nosedive. Presumably Sunrise was looking to exploit the fact that regardless of his [[BaseBreakingCharacter base-breaking]] HostileShowTakeover in ''SEED Destiny'', Kira Yamato is one of the franchise's most enduringly popular characters... but it never occurred to them that just because ''he'' is popular doesn't mean a cheap knock-off would be.
* While the ''Gundam'' franchise itself is still strong, and its merchandise and home video sales did well enough, ''Anime/MobileSuitGundamIronBloodedOrphans'''s mixed reviews and low ratings stemming from DarknessInducedAudienceApathy as well as the equally low ratings for ''Manga/MyHeroAcademia'' has led to the cancellation of the [[PeripheryDemographic for the very popular]] [[Creator/TokyoBroadcastingSystem Sunday 5PM slot by TBS/MBS]] in favor of a variety show; though the latter received a NetworkToTheRescue by [[Creator/NipponTelevision Yomiuri TV]], which is really rare in Japan given the fact that TV channels often take part in the production through fundings. [[note]]Fortunately, ''My Hero Academia'' [[WinBackTheCrowd would go on to perform better ratings, for Season 2, with its new time slot on NTV, regularly making the Top 10 across most of the second half]], [[AvertedTrope just barely averting this trope for that anime]].[[/note]]

* ''Franchise/{{Zoids}}: Fuzors'' is often accused of being one of these by the ''Zoids'' fanbase in North America, but it was in fact the fan-favourite ''Anime/ZoidsChaoticCentury'' that killed the franchise, having gotten such low ratings during its run on Creator/CartoonNetwork that it was cancelled, with the final four episodes only being shown after complaints from the fanbase. ''Fuzors'' was more of a last-ditch effort to salvage what was already a doomed franchise.
* In Japan, ''Anime/ZoidsGenesis'' got a [[SoOkayItsAverage so-so reception]], but TheMerch failed to sell, effectively dooming the chances of another ''Zoids'' anime being made any time soon, and causing Tomy to change its marketing strategy by pandering exclusively to Otaku rather than general audiences as they did before.

!!Other Series
* [[Creator/{{AIC}} Anime International Company]]'s ''[[Anime/ElHazardTheMagnificentWorld El-Hazard: The Alternative World]]'' performed poorly to the point that it was CutShort with the show's [[KudzuPlot way too many plots]] being wrapped up (very poorly) in only a single episode. It also killed off the ''El Hazard'' franchise, with no further work of any kind being done in the decade since. And we never get to see the StableTimeLoop established in the original ''The Magnificent World'' through to its completion.
* After the first season aired, ''[[LightNovel/HaruhiSuzumiya The Melancholy of Haruhi Suzumiya]]'' became one of the most popular anime franchises. Fans clamored for a sequel for years. Then the sequels finally happened... three years later, in 2009/2010 with a second season[[note]]which included "Endless Eight": ''eight episodes'' of the same events happening over and over again, wasting over half the series' content on the non-events of a short, one-chapter story from the light novels. This really didn't help the franchise's reputation.[[/note]] and the well-received ''Disappearance'' movie. However, during those three years, [[http://ultimatemegax.wordpress.com/2013/06/20/the-reasoning-behind-a-lack-of-haruhi-s3/ the roots of death were planted]]: A ScheduleSlip of the light novels since 2007 and still going, Creator/KyotoAnimation realizing that self-owned [=IPs=] would be economically more profitable for them in the long run than animating Kadokawa's [=IPs=] (of which ''Haruhi'' is one) and the demotion of Atsushi Ito, the Kadokawa executive who primarily pushed for ''Haruhi'' in anime form, all coalesced into no person being left around to champion for ''Haruhi'', bringing the series to an abrupt halt. Creator/{{Funimation}} secured the North American rights to ''Haruhi'', which was one of the last licenses that Creator/BandaiEntertainment had around the time of its shutdown. [[http://www.animenewsnetwork.com/news/2013-12-17/the-disappearance-of-nagato-yuki-chan-anime-listed Even the first anime adaptation to be greenlit in years]] is an adaptation of one of its ''[[Manga/TheVanishingOfNagatoYukiChan spinoffs]]'' and failed to save the ''Haruhi'' series.
* The poor reception and behind-the-scenes issues plaguing ''Anime/JewelpetMagicalChange'' forced it to become the final ''Franchise/{{Jewelpet}}'' anime. It was also CutShort to only 39 episodes.
* ''Manga/ShugoChara'''s third season, ''Party!'', bombed so badly that it killed off any chances of adapting the remainder of the manga, and may have even had a hand in the abrupt demise of the manga itself.
* The third season of the ''LightNovel/{{Slayers}}'' anime, which diverged from the continuity from the light novels, wasn't as well-received when it came out, but even then, most prefer it now, because the [[SavedFromDevelopmentHell new fourth and fifth]] seasons that came out eleven years after it were received poorly (and not well-made - ContinuitySnarl, ConspicuousCG, and extreme {{Flanderization}} of the leading heroine, all thrown together with a [[KudzuPlot sloppy]] plot).
* ''Anime/TenchiMuyo'', another Anime International Company franchise, barely escaped this fate in 1997 with ''Tenchi in Tokyo''. Despite having a worse reception as opposed to ''El-Hazard: The Alternative World'' in most regards, ''Tenchi in Tokyo'' managed to last for a full 26 episodes, and only set back the franchise by 5 years instead of killing it altogether. In the same timeframe, attempts to adapt ''Tenchi Universe'' to film were financial and critical failures, and the release of numerous alternate-timeline Tenchi media created a massive ContinuitySnarl [[note]]''Tenchi in Tokyo'' was revealed halfway through its run to be a separate universe from ''Tenchi Universe''; at the same time, a third film was released based on a series of novels that diverged from the first six OVA episodes, ignoring the late ones, with the film itself taking place in the Tenchi Universe timeline.[[/note]]. Even the negative reception of ''Tenchi Muyo GXP'' and OVA 3 (both of which went back to Masaki Kajishima's original OVA timeline) consequently caused the traditional Tenchi lineup to be put on ice for eleven years. Meanwhile, ''Anime/SasamiMagicalGirlsClub'' prompted AIC to scrap any plans for a future ''Pretty Sammy'' series. After that, AIC produced ''[[Anime/TenchiMuyoWarOnGeminar War on Geminar]]'', which didn't feature ''any'' returning characters from the franchise, and was only vaguely connected with any other part of the series. Eventually, AIC successfully revived the series when they produced shorts to promote tourism in 2014 and later produced a fourth OVA series in 2016, bringing Kajishima back to the fold as chief director.
* The AnimatedAdaptation of CLAMP's ''Manga/TsubasaReservoirChronicle'' by Creator/BeeTrain came to a screeching halt after a lackluster second season that had almost nothing but {{Filler}} episodes when there was so much more material left to adapt. Creator/ProductionIG tried to {{Retcon}} it in the ''Tokyo Revelations'' OVA (the adaptation of the Acid Tokyo arc in the manga), but the damage had already been done. It doesn't help that Bee Train went dormant since 2012 and its founder and director Creator/KoichiMashimo retired from the anime industry which any future adaptation of the series uncertain.
* While the ''Franchise/PrettyCure'' series has always aired consistently since it first appeared, there have been ''aspects'' that have been killed off during its 11+ year run:
** ''Anime/FutariWaPrettyCureSplashStar'' ended the original ''Anime/DirtyPair'' duo that the original made popular, leading to series starting with ''Anime/YesPrettyCure5'' to go with ''Franchise/SuperSentai''-style multi-man teams. An attempt to revive the original concept was made with ''Anime/SuitePrettyCure''; it didn't quite work out. ''Anime/MahoGirlsPrecure'' also [[RevisitingTheRoots revisits the roots]] in this manner.
** ''Anime/YesPrettyCure5GoGo'' ended the idea of sequel series, something that would only happen with the ''Anime/PrettyCureAllStars'' series from then on.
** ''Anime/HappinessChargePrettyCure'' forced a ''massive'' revamp of the series starting with ''Anime/GoPrincessPrettyCure'' as well as [[CreatorKiller shaking up the franchise management]] because of it. This was due to the fact that both ''Anime/DokiDokiPrettyCure'' and ''[=HaCha=]'' had each suffered from a very weak second half, turning public opinion against those series[[note]]Both entries had moments that turned people off, including ''Doki-Doki'''s StrangerBehindTheMask moment and ''[=HaCha=]'' getting caught in a RomanticPlotTumor[[/note]]
* Anime no Chikara, Creator/A1Pictures and TV Tokyo's joint original anime project in 2010 (inspired by Fuji TV's Creator/{{Noitamina}} timeslot), was scrapped after the mediocre ratings and BD/DVD sales of its three original anime (''Anime/SoundOfTheSky'', ''Anime/NightRaid1931'', and ''Anime/OccultAcademy''). Regardless of the project and the timeslot's failure, it did inspire creators to release more original anime in 2011 where some of them (''Anime/PuellaMagiMadokaMagica'', ''Anime/TigerAndBunny'', ''Anime/AnoHana'', ''Anime/MawaruPenguindrum'', ''Anime/HanasakuIroha'', etc.) became very successful. Aniplex president, Koichiro Natsume, mentioned in [[http://www.animenewsnetwork.com/interview/2012-12-19/aniplex-koichiro-natsume/ his ANN interview]] that a lot of lessons were learned from the project and they were able to make more successful original anime.
* The mixed-to-negative reception and low BD/DVD sales of ''Anime/BloodC'' nearly killed the ''Blood'' franchise. The movie, ''Anime/BloodCTheLastDark'', attempted to fix the damage. While it performed modestly with home viewers, it flopped at the Japanese box office. Five years later, an {{Interquel}} entitled ''Blood-C: The Last Mind'' was released as a stage play written by Junichi Fujisaku, co-writer of the ''Blood-C'' and ''Anime/BloodPlus'' and a live-action prequel of the series was released on August 2017. The stage play was released well but the live-action movie completely bombed in Japan. In the end, Production IG doesn't have plans for any new anime adaptation of ''Blood'' in the future.
* The ''VisualNovel/UminekoWhenTheyCry'' anime received negative reception and low DVD sales, putting any further adaptations of ''Umineko'' or any 07th Expansion VisualNovel series on hold.
* Fans are probably never going to see an adaption of the Jinchuu arc of ''Manga/RurouniKenshin'' all thanks to the ''Reflections'' OVA which got a lot of backlash from fans including [[CreatorBacklash Nobuhiro Watsuki]] who declared it [[CanonDiscontinuity non-canon]]. Of course, the TV series ended 3 years before ''Reflections'' and by then, the last episodes were purely filler which wasn't received well by fans leading the show to be axed. Though years later, the success of the [[Film/RurouniKenshin live-action movies]] made fans hoping that the Jinchuu arc will be adapted and movie producers are keen enough that they would probably show it in the future. Watsuki released a spinoff manga set after the end of the original manga in 2017 just to keep the franchise alive. The future of the franchise was put in further jeopardy after Watsuki was charged with possession of child pornography, halting production of the manga for the time being.
* ''LightNovel/InfiniteStratos'' will probably never get a third season thanks to its lackluster second season and the light novels were taking too long to be released because of the author's health problems. Volume 11 and a new PC game were released in 2017 just to keep the franchise alive.
* This isn't unheard of with anime slots (or television as a whole), [[OlderThanTheyThink and not the first time a popular timeslot was replaced]]. [[Creator/TokyoBroadcastingSystem The same network]] used to have a Saturday 6 PM slot, for similar anime that was incredibly popular with [[PeripheryDemographic all demographics]], and was launched by the very successful and highly-rated anime, ''Anime/MobileSuitGundamSeed'' and ''Anime/FullmetalAlchemist''. However, starting with ''Anime/BloodPlus'', ratings started to go down heavily, due to its mixed reception (though ''Anime/{{BloodC}}''s own reception would end up [[VindicatedByHistory making]] ''[[VindicatedByHistory Blood+]]'' [[VindicatedByHistory look better in comparison]]) [[note]][[HilariousInHindsight which would be actually surprisingly decent ratings for anime today.]] [[/note]], combined with ''Manga/{{Major}}'''s SleeperHit success on [[https://en.wikipedia.org/wiki/NHK_Educational_TV NHK-Education]], hurt the ratings badly, with ''Manga/AyakashiAyashi'' being CutShort probably marking when the network decided to put the block to sleep, after the first half of ''Anime/MobileSuitGundam00''. [[SubvertedTrope Though a new Sunday 5 PM slot was opened up, and eventually went on to run longer and be relatively more successful.]] [[DoubleSubvertedTrope until 2017, which is mentioned in the Gundam subsection]]. [[note]]To be fair, only a year later, [=NTV=] with its Kansai affailate [=YTV=] would move ''Manga/DetectiveConan'' to that slot, which probably would've damaged the original slot beyond repair, so it was probably the best for the early move. [[/note]]
* ''Anime/{{Robotech}}'' saw itself in freefall thanks to the failure of its toy line, which also resulted in its midquel ''Robotech II: The Sentinels'' getting only a feature-length pilot set between the events of ''The Macross Saga'' and ''The Robotech Masters'' (and happened to be a phenomenon that took down quite a few of its Western-made contemporaries, as the GenreKiller page can attest to), and a severe miscalculation of the audience for ''Robotech: The Untold Story'' at its test screenings in Texas. While it proved to be rather successful, being a fair match for ''Film/{{Aliens}}'' and beating the hell out of Cannon stablemate ''Film/{{Pirates}}'', it was discovered that more adults went to the screenings than did children, and so Cannon pulled the film until it could be further retooled. Unfortunately, it happened at a time when Cannon was [[CreatorKiller drowning in its excesses]], and so a proper North American release ultimately never materialized.
* ''Anime/SuperDimensionCavalrySouthernCross'', from which the aforementioned ''The Robotech Masters'' was derived, proved to be the final season of the ''Super Dimension'' anthology series due in no small part to low ratings which resulted in an early cancellation and a hasty conclusion. Unsurprisingly, it's the only installment in the series, and also the only one from which ''Robotech'' was adapted, that's not yet been released on Blu-ray as of writing.
* Semi-example with the ''Anime/{{Pokemon}}'' movies. [[Anime/PokemonTheFirstMovie The]] [[Anime/{{Pokemon2000}} first three]] [[Anime/{{Pokemon3}} movies]] performed well at the American box office and recouped their budgets worldwide. After the third film failed to out-gross its predecessors in the box office, Creator/WarnerBrothers (owners of Creator/KidsWB, the American broadcaster for the anime at the time) decided to let its contract for future films expire, and the rights were soon picked up by Creator/MiramaxFilms. Miramax proceeded to release ''Anime/Pokemon4Ever'' and ''Anime/PokemonHeroes'' to 249 and 200 theaters respectively (compared to the preceding movies, which were released to around 3,000 theaters), and when the latter failed to reach the $1 million mark, all future ''Pokémon'' films had been made exclusively direct-to-video in the United States (they're still released theatrically in Japan) for more than a decade. It would take over ''thirteen years'' for The Pokémon Company to hand the live-action film rights over to Creator/LegendaryPictures, who finally announced that they and Creator/{{Universal}} would release a ''Pokémon'' movie worldwide theatrically....through the form of ''Film/DetectivePikachu''.
** As for the Pokémon movies themselves, interest in them in both Japan and the West started to drop as a result of ''Anime/PokemonGenesectAndTheLegendAwakened'' creating a second Mewtwo and apparently ignoring ''Mewtwo Strikes Back'', which caused a lot of InternetBackdraft. While ''Anime/PokemonDiancieAndTheCocoonOfDestruction'' was seen as a SoOkayItsAverage SurprisinglyImprovedSequel, the following films provided to very controversial; ''Anime/PokemonHoopaAndTheClashOfAges'' is seen as nothing but dozens of {{Asspull}}s and ending on a DeusExMachina, and ''Anime/PokemonVolcanionAndTheMechanicalMarvel'' was written off as a very predictable ClichéStorm. Both were {{Box Office Bomb}}s in Japan, and ''Anime/PokemonIChooseYou'' would become a ContinuityReboot with at least one sequel.

* The CrisisCrossover ''ComicBook/{{Ultimatum}}'' is one of the reasons why ComicBook/UltimateMarvel ended up being cancelled. It was poorly received, and ended up [[CreatorKiller killing]] writer Creator/JephLoeb's career as a comic book writer as well. Several characters had died, including much of the [[ComicBook/UltimateXMen X-Men]], and many others such as the Ultimate version of Doctor Doom and ComicBook/{{Daredevil}} also deceased. With so many characters dead, many titles, such as ComicBook/UltimateFantasticFour and ComicBook/UltimateXMen were cancelled. Afterwards, what started as a new-reader-friendly AdaptationDistillation devolved to a strange AlternateUniverseFic with a thornier BackStory than the line than had been around since the '60s. The UltimateUniverse would finally end in ComicBook/SecretWars2015, with ''ComicBook/UltimateSpiderMan'' the only remaining title at the time.
* An odd case concerning ComicBook/{{Supergirl}} - the BoxOfficeBomb that was [[Film/{{Supergirl}} her movie]] ended up souring DC so badly that they allowed Marv Wolfman to kill her during ''ComicBook/CrisisOnInfiniteEarths''. This also had the effect of DC declaring a "Superman is the sole survivor of Krypton" mandate that also exiled characters like ComicBook/KryptoTheSuperdog and popular villain General Zod. While ''a'' Supergirl would show up a few years later, the concept of Supergirl being Kara Zor-El, Clark's Kryptonian cousin, would not happen for 18 years afterwards.
* ''ComicBook/SonicTheHedgehogMegaManWorldsUnite'', the second crossover between Sonic and Mega Man, ended up pulling a hat trick and did this for ''four'' comic book series. The intention was that the crossover would use character from other Sega and Capcom series, but this meant Archie comics had to sink a lot of money into licensing fees and paying various artists to do so with the hope it would make back the money. It was also a last ditch attempt to save the Mega Man comic which was suffering in sales by that point. Sadly however the response was lukewarm at best and Archie was barely able to recoup their losses. As such the ''Mega Man'' comic was put in indefinite hiatus. ''Sonic Boom'' was cancelled not shortly after due to negative reception from the ''Rise of Lyric'' game. Ultimately, this even ended up affecting the [[ComicBook/ArchieComicsSonicTheHedgehog main Sonic comic]] and its spin off ''Sonic Universe'', since the crossover ended up stalling the main storylines of those series and contributed to poor sales. With all the cuts Archie was doing due to the relaunch of their own comics, July of 2017 saw them lose the publishing rights for the North American ''Sonic'' comics to Creator/IDWPublishing, who enacted a full ContinuityReboot and effectively put an end to the Archie franchise.

[[folder:Live-Action TV]]
* ''Series/DoctorWho'' was technically canceled three times: First, a break during the summer of '85 while the network deliberated over bringing it back; a six-month "hiatus" while fans badgered the BBC to restore the series to air; and finally a 16-year cooldown period before the 2005 revival. For this reason, it's debatable which serial is the one that put the original ''Doctor Who'' out of business for good. ''[[Recap/DoctorWhoS22E1AttackOfTheCybermen Attack of the Cybermen]]'' is a strong candidate, since it's the embodiment of ''everything'' the show's critics hated. The ''Trial of a Timelord'' arc, conceived as a last saving throw for ''Doctor Who'', impressed no one and ended in the hiatus; the trial was comprised of four hastily-written, convoluted serials, the most baffling of which would have to be ''[[Recap/DoctorWhoS23E2Mindwarp Mindwarp]]''. This series managed to stagger on for an additional three seasons, and though it was beginning to win critics back over, the last two seasons being considered some of the best in the later Classic Season run, the BBC decided ''Doctor Who'' wasn't worth the bother. An American reboot was attempted in 1996, which resulted in the maligned ''Doctor Who'' [[Recap/DoctorWhoTVMTheTVMovie TV Movie]].
* In 1986, Creator/{{ABC}} decided to tap Creator/LucilleBall to star in a third spiritual successor to ''Series/ILoveLucy'', ''Life with Lucy'', in which Ball's character helped run a hardware store she inherited after her husband died. ABC was so confident of Ball's track record--even though she was now 75 years old--that they gave her full creative control, and greenlit it without any pilots or market research beforehand. With Ball and a slew of ''I Love Lucy'' alumni among the cast and crew, what could possibly go wrong? Firstly, ABC scheduled the series on Saturday nights at 8 p.m., which had recently become a [[FridayNightDeathSlot death slot]] for the network. An executive also insisted on incorporating the slapstick comedy that was a trademark of her earlier sitcoms; rather than fuel nostalgia for ''I Love Lucy'', the notion of the 75-year-old Ball performing comedic stunts made critics and viewers fear for her life instead. Ratings for the premiere were fairly good, but when ratings began to steadily fall, ABC cancelled the series after 8 episodes; 13 were produced in total, but Ball was not informed about the cancellation until production wrapped. She was emotionally devastated, believing she was no longer wanted on TV. She died three years later.
* Major League Baseball's Saturday afternoon ''Game of the Week'' went on a two year hiatus (1994-95) after Creator/{{CBS}}, who took over from {{long runner}}, Creator/{{NBC}} in 1990 lost half a billion dollars off of their contract. During the CBS period (1990-93), they didn't air a Saturday afternoon game for all 26 weeks of the regular season (instead covering about 18 on an inconsistent or sporadic basis). On the weeks that they didn't cover a baseball game, they would air other sports programming like golf. Even when {{Creator/FOX}} received an MLB package beginning in 1996 (following the failure of a joint venture between Major League Baseball, Creator/{{ABC}} and Creator/{{NBC}} called The Baseball Network), they didn't start their baseball coverage until Memorial Day weekend. It wasn't until 2007 (18 years after NBC aired their final ''GOTW''), that the ''Game of the Week'' was once again broadcast for each week of the regular season.
* ''Series/{{Heroes}}'' Volumes 3 and 4 (both making up season 3) qualify as such. The second season was a major letdown compared to the strong premier season, but people forgave it because half the season had been [[WhatCouldHaveBeen derailed]] by the [[TVStrikes 2008 WGA strike]] and ThePowersThatBe did the best they could. When season three came along, they expected a return to form; what they got was a RandomEventsPlot with characters acting wildly OutOfCharacter as the writers seemed to change their minds on key plot points three times per episode. The best-known example is Sylar's HeelFaceRevolvingDoor, but it was like that with ''everything.'' By the end of that season, most of the fans had given up on it. There was a fourth season (Volume 5), and while it still had problems many of the remaining fans felt it to be something of a return to form, but by that point few people cared about the show anymore. Not only was the TV series [[CutShort cancelled at the end of that season]], but the graphic novels were also scrapped as well, and the writers and producers couldn't even get a greenlight for a miniseries to give ''Heroes'' a proper last hurrah. NBC rebooted it in 2015 as ''Series/HeroesReborn'', which is set several years later and features Noah Bennett as the nominal main character alongside a mostly new cast... which was then 'concluded' after a single season that received low ratings and mixed reviews.
* The weak reviews and bad ratings of ''Series/LawAndOrderLosAngeles'' (despite NBC's WolverinePublicity of the show) served to kill off that franchise in the US. However, the [[Series/LawAndOrderUK UK remake of the show]] fared better, lasting for seven seasons. ''Series/LawAndOrderSpecialVictimsUnit'' continues to carry the torch in the US, but its continued existence seems to be almost entirely a function of ratings impotence from the rest of the network.
* ''Series/LetsMakeADeal'' (original run: 1963-77, plus revivals in 1980-81 and 1984-86), frequently averted this effect:
** 1990-91: The year was flooded with mediocre game shows, many of which were one-season revivals. With original ''Deal'' host Monty Hall in semi-retirement (although he stayed on as executive producer), the 1990 ''Deal'' revival was hosted by Bob Hilton, who was far more experienced as an announcer than a host, and considered a poor fit. Due to falling ratings, Hall stepped out of retirement and hosted the rest of the season with intentions to scout out a new host for Season 2, but the show was canceled instead.
** 1996: An "edgier" remake called ''Big Deal'' (hosted by Mark [=DeCarlo=]) lasted a whopping six episodes on FOX in 1996 (although it was slated to be UnCancelled in March 1997), and it went down quickly due to phony attempts at being "hip" and "modern" (and constantly being preempted for NFL doubleheaders).
** 1998: A {{pilot}} hosted by Gordon Elliott was proposed by Buena Vista TV (Disney) but also fell through.
** 2003: Hosted by Billy Bush for NBC, and canned after three episodes for many of the same reasons as ''Big Deal''.
** 2009-: With Creator/WayneBrady as host, ''Let's Make a Deal'' has finally started thriving again on CBS daytime. Between 1993 and this version's debut, daytime television had ''no game shows at all'' other than ''Series/ThePriceIsRight'' (also a CBS property).
* By 2008, ''Series/LittleBritain'' was already suffering badly from SeasonalRot and the Creator/RickyGervais-led backlash against classic {{Brit Com}}s and sketch shows. However, the ''Little Britain USA'' series proved to be the final nail in the coffin, getting awful viewing figures and critical reactions on both sides of the Atlantic, and being heavily criticized for worn-out characters and situations, the new characters being even less funny than the existing ones had become, and over-use of the LaughTrack.
* The downfall of Creator/{{NBC}}'s Thursday night "Must See TV" block, can be attributed to the combination of oversaturation of sitcoms all across NBC's line-up (to put things into proper perspective, during the 1997-98 season, NBC had about 18 sitcom slots on Mondays-Thursdays and Sunday), which for the most part seemed nearly identical to one another (i.e. multi-camera shows about young, affluent white people living in UsefulNotes/NewYorkCity), the mismanagement of Jeff Zucker (which on its own, can be considered a {{Dork Age}} of NBC), who because of his "super-sizing" concept for ''Series/{{Friends}}'', made it much harder to nurture another show right after it, the lack of strong shows to replace staples like ''Series/{{Seinfeld}}'', ''Series/{{Frasier}}'' and ''Friends'' (which in the meantime, were usually sandwiched in-between otherwise mediocre or forgettable shows like ''The Single Guy'', ''Series/SuddenlySusan'', ''Series/CarolineInTheCity'' and ''Veronica's Closet'') such as the disastrous American adaptation of ''Series/{{Coupling}}'', other networks' (i.e. Creator/{{CBS}} and Creator/{{ABC}}) Thursday night line-ups becoming increasingly stronger by around 2004, and ''Series/TheApprentice'' moving into the 9 p.m. timeslot.
* ''Series/StargateUniverse'' was a SoapOpera [-IN SPACE!-] that [[InNameOnly couldn't be less like]] ''Franchise/{{Stargate|Verse}}''. Unlike many of these examples, it had a nice little fanbase, but not enough to keep it afloat, and with its failure came the official announcement of the [[{{Cancelled}} indefinite hiatus]] of the awaited ''Series/StargateSG1'' and ''Series/StargateAtlantis'' projects - the kind of 'hiatus' that means you [[DeaderThanDead start dismantling sets]].
* With the 1987 premiere of ''Series/StarTrekTheNextGeneration'', Star Trek was once again a TV staple, and thanks to ''Series/StarTrekDeepSpaceNine'' and ''Series/StarTrekVoyager'', the franchise was still healthy in 2001. Then came ''Series/StarTrekEnterprise''. Plagued with ExecutiveMeddling, a title ambiguous to the general public, a horrible theme song, and two rather weak seasons, the third and fourth seasons, though improved, couldn't keep the show on the air, and it was cancelled in 2005, meaning there was no new Star Trek television for fans to anticipate for the first time in 18 years. And on top of that, ''Enterprise'' was given an infamously awful final episode that essentially served as a giant middle finger to the fans and cast via making it a nonsensical tie-in to ''The Next Generation'' instead of any sort of actual ending to the ''Enterprise'' story. A controversial, but lucrative [[Film/StarTrek reboot film]] by JJ Abrams seems to have resurrected the franchise.
** WebVideo/RedLetterMedia's Mr. Plinkett argues that the true FranchiseKiller was ''Series/StarTrekDeepSpaceNine'''s Dominion War arc - though successful in itself, it showed the Federation in a state of warfare that had never been displayed by the franchise, when previously, ''averting'' such a conflict without firing a shot was usually the main plot. Everything afterward had the choice of either trying to duplicate the success of the Dominion War's high-stakes epic battles with worse writing and lower tension, or trying to go back to the old practice of teasing a conflict before resolving it peacefully, which just looked quaint now. Essentially, the Dominion War burned the series out by being a ToughActToFollow for an entire franchise. It also did not help that the Dominion War arc was very divisive. No one's going to argue that it wasn't great television, but many old-school Trekkers saw it as a ''major'' violation of Roddenberry's ideals (bombing entire planets to get one criminal? Killing an innocent man to ''trick'' a government into joining your war? Being morally okay with both?), a higher-rent rip-off of ''Series/BabylonFive's'' Shadow War arc (the accusation that ''[=DS9=]'' was essentially stolen from B5 did not help), a test-run for Ron Moore's gritty and bleak ''Series/BattlestarGalactica'' or all the above.
** Generally most Star Trek fans blame ''Series/StarTrekEnterprise'' for ending the series due to uneven writing, inane plots and attempting to recreate the Kirk/Bones/Spock dynamic at the cost of the other characters of the show. Add an unlikable Captain who takes his dog on diplomatic missions and abandons said mission when his dog gets hurt. Then you get a show that not only kills the franchise but forces [[Film/StarTrek a reset of the whole universe in order to make it marketable again]]. Chuck Sonnenburg of Website/SFDebris points to the episode "[[Recap/StarTrekEnterpriseS02E05ANightInSickbay A Night in Sickbay]]" as the breaking point for both ''Enterprise'' and the franchise as a whole, referring to how the episode in question received fairly high ratings when it aired, but the show's overall ratings started plummeting afterwards and never managed to recover from this downwards spiral, despite attempts to retool the show, and the otherwise well-received fourth season would turn out to be the last.
* As detailed [[http://tokusatsunetwork.com/2016/06/fact-checked-did-carranger-save-sentai/ here,]] the ''[[Franchise/SuperSentai Super Sentai Series]]'' had been on a gradual ratings slump from 1986's ''Series/{{Choushinsei Flashman}}'' until its nadir in 1990's ''Series/{{Chikyuu Sentai Fiveman}}'', not helped by some serious mismanagement killing [[MerchandiseDriven toy sales.]][[note]]i.e. [[CombiningMecha Max Magma]] toys became shelfwarmers because the robot only appeared in two episodes and was destroyed in the second.[[/note]] However, just when Toei was ready to pull the plug on ''Sentai'', the [[Series/ChoujinSentaiJetman next season]] became a smash hit, with high ratings due in part to a PeripheryDemographic and toy sales.
** Years later, ''Series/TokumeiSentaiGobusters'' did so poorly sales- ''and'' ratings-wise that it's rumored that Bandai actually approached Toei and Creator/SabanBrands and ''asked'' them to skip it in favor of ''Series/ZyudenSentaiKyoryuger'', leading to the creation of ''Series/PowerRangersDinoCharge''.[[note]]It was later revealed that this was only ''part'' of the reason. The other reason was Saban knew that kids would be more enticed with dinosaurs than spies.[[/note]] Not only that, but the annual crossover essentially derailed it from being a crossover between Go-Busters and Kyoryuger to basically "hey, let's get the [[Series/KyoryuSentaiZyuranger other two]] [[Series/BakuryuuSentaiAbaranger Dinosaur Sentai]] together!", with the Go-Busters getting little-to-no additional closure. This is additionally telling with that crossover's post-credits scene where an upgraded version of ''Go-Busters''' BigBad shows up, completely late for the movie and ends up getting defeated [[Series/ResshaSentaiTokkyuger by the passing-by Sentai cameo]].
** In the West, ''Series/PowerRangersOperationOverdrive'' was the defining factor in Disney's grinding the franchise to a halt and selling it back to Saban in 2010.[[note]]Their buyout of Marvel in 2009, filling the same superhero/boys-oriented action niche as ''Power Rangers'' but on a far grander and more reliable scale, was assuredly another factor in the sell. It is also ironic when one considers the [[Series/SpiderManJapan early]] [[Series/BattleFeverJ history]] of ''Super Sentai'' and thus ''Power Rangers''.[[/note]] The only reason ''Series/PowerRangersJungleFury'' and ''Series/PowerRangersRPM'' were made (2007-08 and 2009 resp.) was because Jetix Europe and Bandai respectively ''asked'' them to for each series.
* Although ''Franchise/KamenRider'' has avoided this fate[[note]]while there was a hiatus for the franchise on TV during the 90s, there were movies released during that time period, and the franchise was on hiatus because Shotaro Ishimori did not have any plans for a new TV series at the time[[/note]], the same cannot be said for the show that used to hold the position of airing alongside ''Sentai'' series, ''Franchise/MetalHeroes''[[note]]The audience demographics for ''Metal Heroes'' resembled that of the one for ''Kamen Rider'' today, with many teen and young adult viewers[[/note]]. ''Series/TetsuwanTanteiRobotack'', which increased the LighterAndSofter elements that had been introduced with ''Series/BRoboKabutack'' and was aimed more towards kids, had such low ratings that Toei ultimately decided to pull the plug. While the series has seen new movies as of late, said movies are revivals of already existing shows, and no new TV series have been made since.
* The combination of aging sitcoms like ''Series/FamilyMatters'' and ''Series/StepByStep'' moving to Creator/{{CBS}} (who started ([[StillbornFranchise and ended]]) their own family-friendly Friday night sitcom line-up in 1997-98 called "The Block Party"), the oversaturation of supernatural/magic type shows (''Series/SabrinaTheTeenageWitch'' and new series ''You Wish'' and ''Series/TeenAngel'', which both lasted [[ShortRunners only one season]]), the failure of ''Series/TwoOfAKind'' (which was the last sitcom produced by the previously reliable Miller-Boyett group) starring [[Creator/MaryKateAndAshleyOlsen the Olsen twins]] the following year, and ultimately the ending of ''Series/BoyMeetsWorld'' after seven seasons and ''Sabrina...'' moving to Creator/TheWB after the 1999-2000 season, killed off Creator/{{ABC}}'s TGIF block (although ABC would bring back the TGIF brand for the 2003-05 seasons).
* ''[[Series/DoubleDare1986 Double Dare]]'' had a respectable seven year run and even continued for a few years afterward in re-runs. Then came ''Double Dare 2000'' which was cancelled after two half-seasons, and panned for having an overly loud overbearing host/announcer team who paled in comparison to the iconic Marc Summers/Harvey. Since then, there have been no plans to revive the franchise.
* ''Series/CSICyber'' did not necessarily kill the ''CSI'' franchise, but it was the final nail in the coffin. The franchise's popularity had waned in recent years, with the original show and spin-offs being shuttered in the four years leading up to ''Cyber'''s premiere. ''Cyber'' launched concurrent with the flagship's final seasons and struggled from the beginning with mixed reviews and low ratings. As many fans noted itís not the same as the original ''CSI'' and there are a lot of [[CriticalResearchFailure mistakes]] which would made an IT expert (or in some cases, anyone who used a computer) roll their eyes. Changes in the second season failed to bring in viewers and ''Cyber'' closed out the sixteen-year-long franchise with a reduced season.

* The [[http://en.wikipedia.org/wiki/Altamont_Free_Concert violence at Altamont]] killed not only Meredith Hunter but the whole idea of the "peace, love and music" late-'60s outdoor rock festival that Monterey had pioneered and Woodstock made legendary.
* Similarly, after the violent and criminal tragedies of [[http://en.wikipedia.org/wiki/Woodstock_1999 Woodstock '99]], the owners of the UsefulNotes/{{Woodstock}} name have gone on record to say it will never be used again.
* The death blow to The Love Parade was delivered by the stampede at the 2010 event, where bad design of the location led to the death of 21 people.
* Australia's Big Day Out festival seems to have been killed by its disastrous 2014 shows. Two shows were planned for Sydney, but the second was cancelled after Music/{{Blur}} pulled out and many people accepted the offer of a refund. Most ticketholders treated the event as a very expensive Music/PearlJam and Music/ArcadeFire double bill. The festival's director AJ Maddah then stepped down and sold his share to the Texan company C3 Presents, which was already a part owner. C3 has not staged a Big Day Out in the two years since.
* Music/GuidedByVoices' album ''Same Place the Fly Got Smashed'' was almost this. Frustrated by their lack of success, the band intended ''Propeller'' to be their last album, but that album was far more popular than any that came before it and led to even greater success later on.
* Music/LinkinPark's 2017 record ''One More Light'' was initially this due to its change to a poppy, emotional sound alienating old fans in droves and failing to attract new fans due to the group being long ignored by radio programmers. Since the suicide of Chester Bennington two months later, it's been viewed in a more sympathetic manner.
* Music/TheBeachBoys album ''Summer in Paradise'' was absolutely thrashed by critics and sold so poorly that it pretty much destroyed the band's chance at a full comeback after the success of their 1988 single "Kokomo". A cover album of old hits sung by country singers did nothing to help their career, even ''with'' Brian Wilson producing (though his actual involvement was limited), and by the UsefulNotes/TurnOfTheMillennium they were reduced to a touring oldies band who wouldn't put out another album until 2012.

[[folder:Tabletop Games]]
* The 7th Edition of WarhammerFantasyBattle rules and Chaos supplement, which was more or less broken. Attempt to fix it, the 8th Edition, failed, and led into ContinuityReboot with WarhammerAgeOfSigmar.

[[folder:Web Original]]
* In 2009 and 2010, EQAL, the production company behind ''WebVideo/{{lonelygirl15}}'', ran a contest called The Show Is Yours for fans of the show to create an officially-sponsored, canonical {{spinoff}}. With the Great Recession causing them to struggle financially, EQAL had to put ''WebVideo/LG15TheResistance'' (the franchise's flagship show at the time) on hiatus, leading to this effort to crowdsource the show -- which was already struggling under the weight of a KudzuPlot and multiple spinoffs -- and use it as a springboard to launch a social network called Umbrella. The first spinoff produced through The Show Is Yours, ''[=LG15=]: The Last'', mostly came and went uneventfully, but the second one, ''[=LG15=]: Outbreak'', was a disaster that suffered from a heavily TroubledProduction. Gregory Austin [=McConnell=], the creator of ''Outbreak'', goes into more detail [[https://www.youtube.com/watch?v=cstiCjIk14w here]] about what went wrong. The Show Is Yours, and ''Outbreak'' in particular, essentially ended the franchise for six years until a revival was announced in 2016.

[[folder:Western Animation]]
* The failure of ''WesternAnimation/TheAvengersUnitedTheyStand'' was the final nail in the coffin of the (loosely defined, but still there) [[Creator/MarvelAnimation Marvel animated universe]] that aired on Creator/FoxKids throughout the '90s. All subsequent Marvel cartoons have taken place in other continuities and aired on other networks. It wouldn't be until ''WesternAnimation/{{Ultimate Spider-Man}}'' that Marvel would nurture the idea of a shared animated universe again[[note]]Although ''WesternAnimation/TheAvengersEarthsMightiestHeroes'' is said to take place in the same universe as ''WesternAnimation/WolverineAndTheXMen'' due to Creator/ChristopherYost's involvement in both series[[/note]].
* After ''WesternAnimation/BeastMachines'' there was supposed to be a sequel series (complete with prototype toys made) called ''[[Toys/TransformersTranstech Transtech]]'' and it would have continued even further into the series timeline. While ''Beast Machines'' still had solid ratings, the reception was mediocre and the toys themselves were subpar and didn't sell. Recognizing they had taken the Beast era franchise as far as it could go, Hasbro scrapped ''Transtech'' and imported ''Anime/TransformersRobotsInDisguise'' while they worked on a complete ContinuityReboot with ''Anime/TransformersArmada.'' This did have the interesting effect of splitting ''Franchise/{{Transformers}}'' into many {{Alternate Universe}}s rather than just [[AlternateContinuity Alternate Continuities]].
* ''WesternAnimation/BluesClues'' has several moments that potentially killed the show. Steve Burns leaving in 2002 was the first one. For some reason, some parents and fans of Steve just didn't find Donovan Patton (AKA Joe) {{Adorkable}} enough. However, the show managed to pull on for another 5 years with Patton as host. The second, much clearer one, was the SpinOff, ''Blue's Room'', in 2006. The many inexplicable changes made to the spinoff- specifically, [[ChuckCunninghamSyndrome non-appearance of many of the cast from the main show]] and [[SuddenlyVoiced that Blue can now talk]], aside from the [[ArtShift change to puppetry]], gave the franchise one year to live before production of both shows ceased in 2007 and the franchise slowly disappeared off of Nick Jr.
* Ever wondered why you don't hear much about ''WesternAnimation/FelixTheCat'' anymore outside of merchandising or that 2004 direct-to-video film? You can pin the blame on the failure of 1988's ''WesternAnimation/FelixTheCatTheMovie''. LullDestruction, poor animation and lip-syncing, a RandomEventsPlot (and a poorly executed one at that) and numerous {{plot hole}}s can make this movie painful to watch for even the most avid Felix fan. The 90's cartoon ''WesternAnimation/TheTwistedTalesOfFelixTheCat'' attempted to revive the franchise, but poor ratings for the first season, prompting an unsuccessful {{retool}} in the second season ([[GoneHorriblyWrong which did even]] ''[[GoneHorriblyWrong worse]]'' [[GoneHorriblyWrong in ratings]]), quickly brought Felix to an early grave yet again. Don Oriolo, who formerly held the rights to the character and related intellectual property, then tried to bring Felix to the CGI world in the form of another cartoon, but that went nowhere and the rights to Felix and related properties were eventually passed on to Creator/DreamWorksAnimation and Creator/{{Universal}}. Neither studio has a concrete plan to resurrect Felix.
** Even before those was the failure of the early 30's sound cartoons; Pat Sullivan made little effort to upgrade the Felix cartoons to sound (not helped by his private life being in shambles due to his wife's alleged suicide and his heavy alcoholism) and when he did, they were rushed, sloppy, and far behind the times, resulting in the Felix cartoon series getting forgotten by the far more popular MickeyMouse shorts--Sullivan's subsequent death put the final nail in the coffin for his animation studio. An attempt to revive the cartoons was done in the mid 1930's by Creator/VanBeurenStudios; while the cartoons were seemingly well received despite having little in common with the character's previous appearances, when RKO negated Van Beuren's contract in favor of distributing Disney, it caused Van Beuren to go belly-up, thus sending Felix to an early grave yet again, [[StillbornFranchise after only three color shorts]]. What caused the franchise to not fully die out, is that despite the cartoons being put on ice, Felix still ran in newspaper and magazine comics for quite a long time.
* After the second season of ''WesternAnimation/{{Gargoyles}}'', creator Creator/GregWeisman jumped ship, and a third season called ''Gargoyles: The Goliath Chronicles'' sank the franchise on TV. Greg wrote a comic series to replace the third season, but unfortunately it didn't sell well enough to keep up once [[ScrewedByTheNetwork Disney hiked up the licensing fee]].
* The ''WesternAnimation/HollyHobbieAndFriends'' direct-to-DVD series has an interesting case of this when the producers of the show decided to change several aspects of the franchise from the fifth DVD on. Said DVD, ''Fabulous Fashion Show'', was so badly reviewed across the board, with an overall 1.3/5 on Amazon with 18 reviews, compared to 4+ star averages for the others, that it all but killed the franchise. The subsequent DVD, ''Marvelous Makeover'', rebounded to 3.3 stars, but the various changes that had been made to the series, such as moving to 22 minute stories and replacing most of the voices, were still generally poorly regarded. Making things worse was the shoddy voice replacement job- the new cast sounds nothing like the old one, and while they opted to use a NonSingingVoice for the titular character, the singing voice and speaking voice wasn't even matched either. Aside from that, the characterizations were all botched and the characters were passing the IdiotBall around. The show's final picture book release was seen a bit later in 2008, and afterwards, production on all media was discontinued entirely.
* Universal released ''WesternAnimation/JetsonsTheMovie'' in 1990, complete with ConspicuousCG, a GreenAesop played out with a GangOfCritters that was essentially a rewrite of an old episode of ''Star Trek'', and reuniting nearly all of the surviving original cast members[[note]] Daws Butler, the voice of Elroy Jetson, had died in 1988; the role was re-cast with a young Patric Zimmerman, nearly a decade before he voiced Revolver Ocelot in the ''VideoGame/MetalGearSolid'' series.[[/note]] save for Judy Jetson being voiced not by Creator/JanetWaldo but by '80s pop starlet Tiffany thanks to ExecutiveMeddling. The film also marked the last performance ever of noted voice artist Creator/MelBlanc (Mr. Spacely), who was still recording while in the hospital (as he had years before then) and died before the film was completed, as well as George O'Hanlon (George), who by that point had to have the lines read and acted to him before recording, who also passed away before he could quite finish the film. Both Blanc and O'Hanlon's remaining lines had to be completed by Creator/JeffBergman. Penny Singleton did not die during production like Blanc and O'Hanlon, but the movie remained her last acting role until her death thirteen years later. Coming on the heels of the 1980s ''Jetsons'' revival (the new syndicated episodes and two TV movies), this film's disappointing box office and harsh critical reviews were apparently enough to send the franchise back into hibernation. It has stayed there ever since, and despite rumors of a potential live-action film occasionally floating about, [[DevelopmentHell no such film has ever been made]]. A direct-to-video film crossing over with Creator/{{WWE}} was released in 2017.
* In a rare example of a character being a one-person Franchise Killer, Elmyra managed to be the prime cause for the untimely demise of ''WesternAnimation/PinkyAndTheBrain''. This is even pointed out in the new theme song for ''WesternAnimation/PinkyElmyraAndTheBrain'':
-->"It's what [[ExecutiveMeddling the network wants]], [[LampshadeHanging why bother to complain?]]"
* The negative reception and ratings failure of ''WesternAnimation/PlanetSheen'' was enough to kill off all interest in the ''[[WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius Jimmy Neutron]]'' franchise for the forseeable future.
* The abrupt cancellation of ''WesternAnimation/RenAndStimpyAdultPartyCartoon'' put the series on the kibosh, as no plans to revive the series have come about despite Creator/JohnKricfalusi's attempts to do so. The lackluster sales of the DVD sets didn't help this. It also helped put an early end to the entirety of the then-new Creator/{{Spike}}'s animation block, thus taking down ''WesternAnimation/{{Stripperella}}'' (which was also hampered by a lawsuit) and ''WesternAnimation/GaryTheRat'' along with it, although the former was at least popular enough once it hit DVD...only to see more negative reception pile on over the years.
* ''WesternAnimation/ScoobyDooInArabianNights'' helped to kill off the franchises of WesternAnimation/YogiBear[[note]]Though things were set in motion for Yogi by the failure of ''WesternAnimation/YoYogi'' three years prior[[/note]] and WesternAnimation/MagillaGorilla, as this was Magilla's last animated appearance, and the final cartoon by Creator/HannaBarbera to feature Yogi Bear and Franchise/ScoobyDoo, although the latter was revived with great success in 1998 by Warner Bros. with ''WesternAnimation/ScoobyDooOnZombieIsland'', making Scooby a CashCowFranchise for them in the years since. Yogi Bear has since had a few new cartoons by John Kricfalusi, but hardly anybody's seen them, as well as a financially successful, but critically ravaged, live-action/CGI film released in 2010.
* The ratings failure of ''WesternAnimation/SuperMarioWorld'', along with the cancellation of ''WesternAnimation/CaptainNTheGameMaster'' and the closure of NBC's Saturday morning cartoon block, killed off any further attempts to keep the Franchise/SuperMarioBros on television. The only subsequent ''Super Mario Bros''.-related television series made since then was ''The Super Mario Challenge'', a live-action game show from the United Kingdom that aired and ended around the same time as ''World'' (although one could also count the ''WesternAnimation/DonkeyKongCountry'' CGI cartoon). However, ''Super Mario World'' may be one of the rarest examples of a cartoon being [[VindicatedByHistory Vindicated by]] WebAnimation/YouTubePoop.
* The ''WesternAnimation/{{Rugrats}}: Tales From the Crib'' series was a [[DirectToVideo direct-to-DVD]] series of FracturedFairyTale-esque movies, which attempted to make the original series popular again after it ended. However, there were only two entries in the series; "Snow White" and "Three Jacks and a Beanstalk", as the latter failed to impress. This also forced the "Pre-School Daze" spin-off (which had its episodes included as bonuses on the [=DVDs=]) to end at only four episodes.
* The failure of ''WesternAnimation/BewareTheBatman'' (not helped by [[InvisibleAdvertising lack of advertising]] and [[ScrewedByTheNetwork few reruns]]), along with the success of ''WesternAnimation/TeenTitansGo'', led to the death of ''WesternAnimation/DCNation'' as well as action-adventure series on Cartoon Network (at least, those without heavy comedy elements) in general for the next three years.
** Regarding family friendly DC animated shows, the creators and producers started relying more on DVD and digital services, along with sites like YouTube, hence the longevity of shows like ''WesternAnimation/DCSuperHeroGirls'' .
* With ''WesternAnimation/TheBoondocks'', when series creator Aaron [=McGruder=] left after Season 3 due to a contract dispute with Creator/SonyPictures and Creator/AdultSwim, Season 4 was developed without him. Due to heavy fan backlash against [[PostScriptSeason what would be the show's final season]], along with [[WhatCouldHaveBeen aborted plans]] for a [[{{Website/Kickstarter}} crowdfunded]] live-action feature-film based around the supporting character Uncle Ruckus, it's unlikely that the franchise will continue.
* ''WesternAnimation/DoraTheExplorer'', Nickelodeon's longest-running pre-school show, got cancelled after it was losing in ratings to ''[[WesternAnimation/DocMcstuffins Doc McStuffins]]'' and ''WesternAnimation/SofiaTheFirst''. Nickelodeon got jealous of how popular those shows were, and decided to create ''[[WesternAnimation/DorasExplorerGirls Dora And Friends: Into The City!]]'', an aged-up spin-off where Dora and her friends help others in their city by using magical charm bracelets [[FollowTheLeader to cash in on how both shows had characters who used magical items to help their friends]]. However, it failed for quite a few reasons: First, Dora's animal friends from the older series, as well as Swiper, were replaced by human girls and a boy. Secondly, Nickelodeon made the decision to schedule it against the two aforementioned Disney Junior shows and ''WesternAnimation/TeenTitansGo'' [[note]][[PeripheryDemographic which gets its highest ratings with kids aged 2-5 despite it being aimed at a much older demographic]][[/note]] repeats. The third reason was that the timeslot of the show was often shuffled around, and many episodes had months-long delays. Another reason was that the toys for the show were poorly made and often broke apart. However, the biggest reason was that their newer program ''WesternAnimation/PawPatrol'' was becoming a massive hit amongst preschool aged kids, so Nick started cashing in on that instead. After the failure of the show, Nickelodeon pulled it from their morning schedule and shoved any Dora-related content in early-morning or late-night timeslots to hide their shame on the Nick Jr. channel.
* The ratings bomb that was ''WesternAnimation/SonicUnderground'' led to Creator/DICEntertainment losing the license to produce ''Franchise/SonicTheHedgehog'' television series and left the West without an animated ''Sonic'' series for 15 years (barring the Japanese-made anime ''Anime/SonicX'') until ''WesternAnimation/SonicBoom'' in 2014. Unlike the previous series, however, ''Sonic Boom'' is co-produced by Sega in-house.
* The [[ScrewedByTheNetwork poor scheduling by networks]] of ''WesternAnimation/TheAdventuresOfTeddyRuxpin'' led to the death of any new stories being produced for the Teddy Ruxpin franchise, and also had a hand in bankrupting Worlds of Wonder.
* ''WesternAnimation/HeyArnold'': Despite making five times its budget, ''WesternAnimation/HeyArnoldTheMovie'' was still considered a BoxOfficeBomb and was critically panned. The failure of this film led to the cancellation of ''WesternAnimation/HeyArnoldTheJungleMovie'' (until it was UnCanceled 15 years later) and likely why the remaining episodes of ''Hey Arnold!'' were aired sporadically until the final one aired in 2004, three years after production of the series ended. However, with the ''Jungle Movie'' being UnCanceled in 2017, Nickelodeon may have plans to resurrect the series.
