[[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]].

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 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 so that no one can continue it without using {{Prequel}}s, {{Retcon}}s or just [[ContinuityReboot rebooting]] the whole thing.

!!Franchise/{{Gundam}}
* 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/SciFiChannel SyFy]] revived the franchise by airing ''Anime/MobileSuitGundam00.''
* Its sequel ''[[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 SyFy, 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''. A movie meant to tie up the Cosmic Era timeline has been stuck in DevelopmentHell for years (due to the declining health of one of the writers), and its fate is uncertain.
** And well before the fallout of ''G Gundam'' and ''Gundam SEED'', there was 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 onto ''Anime/MobileSuitGundamWing'', a series that (at the time) was one of the more modern ''Gundam'' series (made in the 90s and all). The result? ''Mobile Suit Gundam'' never finished its initial run, with Cartoon Network claiming that it had been pulled due to 9/11. 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 SelfDemonstrating/TheJoker no less), and as a result Toonami ran the final two episodes of the series (specifically the [[BigBadassBattleSequence Battle of A Bao A Qu]]) 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 darkest in Gundam canon, with the series being introduced during a violent invasion attack, featuring a VillainProtagonist, and the first major antagonist being a ''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. The overall reaction and viewership decline of the series resulted in ''Gundam'' being kicked off of the Tokyo Broadcasting System, where it had been part of the lineup for years. 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 new levels that infuriated fans, ''that'' is when ''AGE'' took a nosedive and nearly killed the franchise.

!!Other Series
* ''Franchise/{{Digimon}}'':
** The anime ''Anime/DigimonFrontier'', which followed the [[ToughActToFollow popular]] ''Anime/DigimonTamers'', killed the anime franchise for three years due to leaning back on a HenshinHero concept instead of the {{Mons}} that the entire intellectual property is based on. Its successor, ''Anime/DigimonSavers'', didn't do well enough to keep the franchise on hiatus for ''another'' three years until the release of ''Anime/DigimonXrosWars''.
** In America, ''Savers'' (re-titled as ''Digimon Data Squad'' for English audiences) killed the franchise. In this case, [[{{Bowdlerise}} Toon Disney's treatment of the series]] is probably to blame. Desperate to get the ''Digimon'' craze over with, Creator/ToonDisney's edits ended up turning ''Data Squad'' into a 4Kids-like disaster, [[CulturalTranslation removing numerous references to Japanese culture and replacing it with American-oriented ones]], turning a villain in one episode from a giant bomb '''to a giant orange fruit''' and [[spoiler:threatening to flood an amusement park instead of blowing it up]], forcing characters to NeverSayDie and removing all scenes of characters dying or brandishing firearms. The mess Toon Disney made was so distressing that pre-existing Digimon fans refused to watch it. Once the dub ended its run, Disney sent the ''Digimon'' license back to Saban in 2010[[note]]as part of a deal that saw Saban reacquiring the rights to ''Franchise/PowerRangers''[[/note]], and ''Savers''' successor, ''Anime/DigimonFusion'', was finally picked up by Creator/{{Nickelodeon}} for an English dub in 2013.
* 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 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 ''Anime/ElHazardTheMagnificentWorld'' through to its completion.
* After the first season aired, ''TheMelancholyOfHaruhiSuzumiya'' was the hottest otaku property around. Fans clamoured 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. What little did anyone know at the time is that [[http://ultimatemegax.wordpress.com/2013/06/20/the-reasoning-behind-a-lack-of-haruhi-s3/ during those three years and counting were planted the roots of death]]: 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 man at Kadokawa who primarily pushed for ''Haruhi'' in anime form, all coalesced into no person being left around to champion for ''Haruhi'', and so the series died a slow and painful death out of inactivity; nowadays, it's only the hardcore fans left wanting a third season. It's also telling that out of all the major properties for which Creator/BandaiEntertainment still had licenses at the time it left the North American anime market, ''Haruhi'' is the last to have its license picked up by another company. [[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 [[Manga/TheVanishingOfNagatoYukiChan one of its]] ''[[Manga/TheVanishingOfNagatoYukiChan spinoffs]]''.
* ''Manga/ShugoChara'''s third season, ''Party!'' bombed so badly that it prevented the rest of the manga from getting adapted, 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 one year earlier with ''Tenchi in Tokyo''. Despite being in most regards worse than ''[[Anime/ElHazardTheMagnificentWorld El-Hazard: The Alternative World]]'', ''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 the big screen 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 in its run to be a separate universe from ''Tenchi Universe''; at the same time, a third movie 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]]. The poor critical and fan reception of GXP and OVA 3 (both of which went back to Kajishima's original OVA timeline) put a nail in the coffin for the traditional Tenchi lineup, and ''Anime/SasamiMagicalGirlsClub'' killed the ''Pretty Sammy'' stuff. What would come after (''[[Anime/IsekaiNoSeikishiMonogatari War on Geminar]]'') didn't feature ''any'' returning characters from the franchise, and was only vaguely connected with any other part of ''Tenchi''. The only thing the franchise has going for it now are shorts to promote tourism.
* The AnimatedAdaptation of CLAMP's ''Manga/TsubasaReservoirChronicle'' 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. They 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.
* Subverted with the ''Franchise/PrettyCure'' series. The relative failure of ''Anime/YesPrettyCure5GoGo'' wouldn't kill the franchise outright, but it would lead to the series not having any more direct sequels outside of the ''Anime/PrettyCureAllStars'' movie series.
* ''Franchise/{{Zoids}}'':
** ''Anime/ZoidsFuzors'' is often accused of being one of these by the English-speaking ''Zoids'' fanbase, 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.
** Similarly, in Japan, ''Anime/ZoidsGenesis'' was a franchise killer; the anime 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.

[[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 ''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 through it was beginning to win critics back over, 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]].
** A major problem for Classic Who was its large audience: Many were impressionable children, but others were simply grown-up fans who expected a level of maturity from the show. These two factions did not get on with each other: A cabal of MoralGuardians attacked the TomBaker era, with its Hammer Horror tropes for being too scary for kids (famously derided as "teatime brutality for tots" by Mary Whitehouse); in a bid to curry favor with them, the show's producers dialed down the horror in favor of light comedy. The politics were the next to be thrown overboard, as the UK under MargaretThatcher was no place for the peace-loving, anarchic tone of the Classic Series. The series became bloodier and very, very '80s, with head writer Eric Saward spending more time fleshing out his amoral, Creator/ClintEastwood-style bad guys than the show's stars. Finally, in a last bid to win back the alienated fans, producer John Nathan-Turner overloaded the show with {{continuity nod}}s and {{call back}}s, often forgetting the context of where the references came from. It wasn't until much later that ''Doctor Who'' considered writing serials based on the turmoil backstage: [[Recap/DoctorWhoS22E2VengeanceOnVaros "Vengeance on Varos]]", itself a parody of sensationalist TV, and [[Recap/DoctorWhoS25E2TheHappinessPatrol "The Happiness Patrol"]], set in a Mary Whitehouse-themed dystopia[[note]]albeit one ruled by [[NoCelebritiesWereHarmed a pastiche]] of MargaretThatcher, WordOfGod says[[/note]], where being unhappy is a crime, and where stormtroopers forcibly paint the TARDIS bright pink so as not to look 'depressing.'
* 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 {{FOX}} received an MLB package beginning in 1996 (following the failure of a joint venture between Major League Baseball, {{ABC}} and 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 can't even get a greenlight for a miniseries to give ''Heroes'' a proper last hurrah. NBC plans on rebooting it with ''Heroes Reborn'', set in the same universe, but with a new cast of characters.
* 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 UK remake of the series is doing well and has been picked up for a seventh series. ''Series/LawAndOrderSpecialVictimsUnit'' continues to carry the torch in the US, as well, 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".
** 1998: A {{pilot}} hosted by Gordon Elliott was proposed 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 Wayne Brady 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 {{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 from 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. {{CBS}} and {{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. A controversial, but lucrative [[Film/StarTrek reboot film]] by JJ Abrams seems to have resurrected the franchise.
** The much hated (by both the fans and the ''cast'') final episode "These Are the Voyages", was purely adding insult to injury. The [[StarTrekExpandedUniverse relaunch novel series]] couldn't {{retcon}} it fast enough. Note that this is the ''only'' episode in the history of ''Star Trek'' (counting the animated series, that's 725 episodes) that's ever been directly and intentionally contradicted by a novel.
* Fantasy Leader, a Blogspot user, wrote a detailed essay on what was almost the Franchise Killer for ''Franchise/SuperSentai'' [[http://valsagfantasy.blogspot.com/2010/08/super-sentais-almost-cancellation-and.html here]]. To recap: the coincidental collision of a gradual BrokenBase in the fandom that built up starting with ''Series/ChikyuuSentaiFiveman'' five years ago and a pair of [[GenreKiller Genre Killing]] [[TooSoon real-life incidents]] outside of the fandom[[note]](The Great Hanshin Earthquake which occurred a few months before the series debuted, and the sarin gas attacks in the Tokyo subway which occurred shortly after ''[[Series/ChourikiSentaiOhranger Ohranger's]]'' premiere, made the 1995 season's DarkerAndEdgier alien robot invasion plot very untenable)[[/note]] led to show ratings falling to a new low in ''Series/ChourikiSentaiOhranger'' and Toei was prepared to pull the plug... until they noticed that ''Ohranger'' toy sales somehow reached a monstrous new high for ''Sentai'' overall.
** 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 two other 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 was because Jetix Europe and Bandai respectively ''asked'' them to for each series.
* 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 ''{{Teen Angel}}'', which both lasted [[ShortRunners only one season]]), the failure of ''Two of a Kind'' (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).

* 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 {{Woodstock}} name have gone on record to say it will never be used again.

[[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.
* After ''WesternAnimation/BeastMachines'' there was supposed to be a sequel series (complete with prototype toys made) called ''[[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]].
** If you're still confused over why it's considered a Franchise Killer, let's just say this; up until ''WesternAnimation/BeastMachines'', all Transformers franchises were made in or spun off from ones made in the West; ''after'' ''Beast Machines'', ''no'' Transformers series would be developed in the West until ''[[Film/{{Transformers}} almost a decade later]]''.
* ''WesternAnimation/Ben10Omniverse'' was this to the {{Ben 10}} franchise; technically, it had better ratings than the two previous entries, but [[BrokenBase the fanbase was]] [[UpToEleven even more divided on it than it was on those]], and the toy sales were rather low, resulting in the show being ScrewedByTheNetwork.
* ''WesternAnimation/BluesClues'' has several moments that potentially killed the show. Steve Burns leaving was the first one. For some reason, some parents just didn't find Donovan Patton {{Adorkable}} enough. However, the show managed to pull on for another 5 years with Patton as host. The second, more clearer one, was the SpinOff into ''Blue's Room'' in 2006. The many 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 pattering off into obscurity.
* 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 ''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 an unsuccessful retool in the second season quickly brought Felix to an early grave yet again.
** 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 whilst the cartoons were put on ice, Felix still ran in newspaper and magazine comics for quite a long time.
* After the second season of ''WesternAnimation/{{Gargoyles}}'', 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 an animated ''WesternAnimation/TheJetsons'' feature film 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 original cast members save for '80s pop starlet Tiffany voicing Judy Jetson thanks to ExecutiveMeddling. The film also marked the last performance ever of noted voice artist 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 a sound-alike. 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, a potential live-action film being stuck in DevelopmentHell for years notwithstanding.
* 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'' has killed off all interest in the ''[[WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius Jimmy Neutron]]'' franchise in the forseeable future.
* The abrupt cancellation of ''[[WesternAnimation/TheRenAndStimpyShow Ren & Stimpy: Adult Party Cartoon]]'' put the series on the kibosh, as no plans to revive the series have come about. 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.
* ''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 Creator/JohnKricfalusi, but hardly anybody's seen them, as well as a financially successful, but critically ravaged, live-action film.
* 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''.
