[[caption-width-right:350:The exact moment this trope was born.]]

->'''Angelica:''' Aunt Didi, what's disco?\\
'''Didi:''' Oh, nothing, sweetheart. It's something that happened a long time ago and it's never, never coming back, so don't you worry.

The polar opposite of VindicatedByHistory, and a variant on SeinfeldIsUnfunny. This is something -- an individual character, an individual song or book or game, an entire genre -- that was very, very popular in its day. But at some point, it somehow just got too popular. It was talked about on ''every'' radio station, on ''every'' TV network, on ''every'' chat room (not that they'd been invented then...). It was [[WolverinePublicity overexposed until people got bored with it]], and it got so much publicity and [[FollowTheLeader so many bad knockoffs]] that there was plenty of time to notice each and every flaw and dissect them under a microscope. Soon, [[FranchiseOriginalSin small problems were regarded as unavoidable flaws]]. The final tell-tale sign is when ridicule, or even hate, comes not just for [[{{Hatedom}} the thing itself]], but for [[FanHater its fans]]. [[AcceptableTargets They become the subject of nasty, highly-specific stereotypes]], and [[SugarWiki/GushingAboutShowsYouLike gushing about how you like it]] online is considered {{troll}}ing.

Ten years later, almost nobody will admit that they ever liked it, and the only mention in the media will be [[AnyoneRememberPogs cheap jokes about the fad]]. [[ILoveTheExties Retrospectives]] of the time in which it was popular will either point to it as a symbol of [[IWasQuiteAFashionVictim everything wrong]] with that time period's taste in music, television, cinema, fashion, literature, etc., or quietly skip over it and [[OldShame pretend it never happened]]. It may get revived decades later as kitsch, but it's unlikely to be popular on its own merits again. In fiction (and RealLife), a DiscoDan is a rare admirer who refuses to accept the judgment of history and passionately holds on to the belief that the dead thing is still as big as it always was -- usually with comical results.

Of course, twenty years later, [[PopularityPolynomial the situation may change again]].

Sometimes caused by people saying that ItsPopularNowItSucks too much, but not always: at its height, these people are typically not very vocal. It's particularly common with things that never had a cult following to begin with -- they went from nowhere to everything, and then back to nowhere, very suddenly. This is essentially HypeBacklash after something faded from popularity with the haters still remaining.

Another cause of this trope, other than simple overexposure, is a franchise doing something that [[TheyChangedItNowItSucks is widely rejected by the established fandom]] and fails to allow it to pick up a new audience. Falling victim to TheChrisCarterEffect or a KudzuPlot is one of the easiest ways for this to happen, as fans' memories of earlier seasons, films or books are tainted by the realization that the plot that they had spent years following is going nowhere, is being made up on the fly with little forethought, and isn't likely to be resolved. Consequently, the now-former fans tell newbies not to bother. Ending a series on a [[BaseBreaker base-breaking]] note is another way to do this. In a nutshell, the series enters a DorkAge that it not only never gets out of, but which rubs off on when it was still good. LongRunners may be troubled by [[ValuesDissonance changing times]] ([[JumpingTheShark and thus,]] [[PeripheryHatedom changing tastes]]), which can lead entire genres to being [[DeadHorseGenre not even the shadow of that they were before]].

Compare JumpingTheShark, PeripheryHatedom, DeadHorseGenre, DarthWiki/FallenCreator, and {{Hatedom}}. Contrast VindicatedByHistory and NostalgiaFilter. If a single work is perceived as rendering something Deader Than Disco, it's a CreatorKiller, FranchiseKiller or GenreKiller. Compare ''and'' contrast UnintentionalPeriodPiece, when a work can be precisely dated to a specific era, but it may (or may not) have remained popular up to the present day.

Not to be confused with DeaderThanDead, which is a completely different trope, or GratuitousDiscoSequence, which is actually about disco.
