Given the pace of technology changes, there are lots of examples with computing.

[[folder:Computer Programs and Hardware]]
* Internet portals like Prodigy, [=CompuServe=], iMagination, etc. They were called portals because that's how you usually entered the Internet -- they had a lot of links to useful sites, news and a content listing. When the Internet was fledgling during the '90s, they were extremely popular. However, the more efficient, less resource-intensive, and free World Wide Web put them on a steady decline. Today, America Online is the only one of these services that still remains, and even that's pretty much [[WereStillRelevantDammit on its last legs]], remembered as a symbol of all that was wrong with the mainstream internet in the '90s.
* Floppy drives and floppy disks (commonly known as the A:\ drive to Windows users[[note]]DOS and Windows are the only operating systems to label drives this way[[/note]]) are mostly dead thanks to the fast advancements in computer and storage technology. The most basic CD or DVD simply has capacity orders of magnitude larger than the floppy disk and DVD and USB drives perform much faster than a floppy drive. The popularity of streaming and downloads has also made optical discs in turn largely obsolete.
* Funnily, the aforementioned rise of the CD-ROM format started a five or six year trend that would ''itself'' become this: the so-called "Multimedia Revolution." During the early 1990s, as the CD-ROM format was becoming mainstream, "multimedia" had become a ''huge'' buzzword in the computing industry. The idea was that basic domestic activities, from mothers looking up dinner recipes to teenagers researching the first World War, could now be done on home computers thanks to the large amounts of information [=CDs=] could store. Between 1991 and 1996, numerous "multimedia applications" were developed, from Microsoft Encarta (a full-fledged encyclopedia on CD-ROM) to {{edutainment game}}s for children, such as the ''VideoGame/PuttPutt'' series.\\\
Two things effectively killed the "multimedia" movement. The first and most obvious was the rise of the World Wide Web, quickly rendering CD-ROM-based reference software obsolete. The other was the rise in UsefulNotes/MicrosoftWindows 95 as a gaming platform. Originally, Microsoft was pushing Windows 95 as the "ultimate multimedia powerhouse", with Microsoft Encarta being its big KillerApp. Around that same time, a little game called ''VideoGame/{{Doom}}'' was released. After audiences turned out to be far more intrigued by ''Doom'' than Encarta, Bill Gates gradually phased the "multimedia" focus out of his promotions of Windows 95, instead emphasizing its potential as a gaming platform. This was heavily fueled by the creation of [=DirectX=], a game development library that made computer game development and installation easier than it ever was on [=DOS=]; no longer did gamers need to mess with confusing soundcard configurations or expensive memory managers to get a single game running, as [=DirectX=] took care of all those issues automatically. Furthermore, many later interactive [=CD-ROMs=] were [[FollowTheLeader cheaply-made cash grabs]] with little to offer; a perusal of ''Magazine/MacAddict'' in the late '90s will find nearly every other CD-ROM getting thoroughly panned. Today, the "multimedia movement" is seen as a joke and little more than a footnote when discussing the rise of the personal computer, its place in history having been completely overshadowed by the internet.
* Many Windows operating systems are obsolete due to newer, faster, and more secure versions being released every few years. Windows XP is still widely used by schools and many workplaces--including many governmental units (many a new hire at a [[AmericanCourts US federal courthouse]] is surprised to find the computer runs XP)--and it is also still used by consumers who do not wish to upgrade their OS, even though Windows XP is no longer supported by Microsoft. Some places may still use Windows 95/98/2000 as well just for their simplicity (and thus making certain work tasks quicker to do without having to go through more complicated software), but those are incredibly rare to see.
* Having certain e-mail providers is seen as sure signs that you are an old person who probably barely uses the internet. These include Yahoo, Hotmail, AOL, and various discontinued internet providers like Netzero. In fact, pretty much any e-mail provider other than Gmail seems to be slipping into this trope. However, Hotmail may end up seeing a second life as Outlook (since the Hotmail accounts were grandfathered when the change occurred).
* [=WebRings=], Topsites and internet directories have been affected by this trope, with the prominence of Google (which most discounts their effects on a site's SEO) and the rise in social networks as a means of promotion having made things like giant lists of links and the like kind of useless. Indeed, some might say the only people who even visit such sites nowadays are webmasters trying to promote their work (instead of end users trying to find new content). This can be seen by how the Open Directory Project/DMOZ has slowly fallen in relevance, and even completely been dropped as a feature by Google in recent years.
* Dedicated instant messenger programs (such as [=ICQ=], [=AOL=] Instant Messenger, and MSN Messenger) for computers were very popular among Internet users during the days when a significant percentage of them had dial-up connections, as they would allow you to see when a friend logged on and instantly open a chat with them. But the rise in popularity of text messaging, cell phone plans with free long distance calling, social media sites like Facebook adding built-in chat features, gaming clients like Steam and Battle.Net having built-in instant messaging, and free video chat programs like Skype and Tango have caused dedicated instant messengers to become somewhat obsolete. These days, [=IM=] programs are mainly used by businesses as a way of allowing quick, easy communications between employees who may not be sitting right next to each other.
** For that matter, the concept of meeting and chatting with total strangers on the Internet seems to have become this, now that issues like cyber-pedophilia and phishing have soured the once novel concept of meeting different people from around the world with just your computer.
* Website/GeoCities, which allowed many early denizens of the 'Net to make their own Web pages without needing to know how to use HTML. However, SturgeonsLaw was in full force, as seen in [[http://www.techradar.com/us/news/internet/web/geocities-closes-fond-memories-of-free-sites-and-terrible-web-design-644763/2#articleContent this]] article: "It didn't take long before this simple change altered the face of the internet. [=GeoCities=] gave everyone a place to call home, and then proved that most of us don't really have a lot to say. It didn't take long before [=GeoCities=] became home to the bottom of the Internet. Crackpot theories. Inane ramblings. Worm distribution." and "I think that most people set up a GC page as a novelty and then abandoned it leaving a whole lot of cyber-trash behind. That kind of ruined the overall [=GeoCities=] vibe; it wasn't long before you had to muck through a few dozen one-offs to find a page that was regularly maintained and had good, interesting content." [=GeoCities=] was often seen as a haven of garishly colored pages full of blink tags and animated [=GIFs=]. Also, the rise of blogging, as well as social media like Facebook and Youtube[[note]]itself now seen as home to the bottom of the internet[[/note]], rendered the concept of a free personal homepage obsolete, while those who still wanted to build their own Websites moved on to more advanced tools.
* By proxy, comment sections in major news articles and editorials significantly dwindled during the '10s. The initial idea of comment sections was that anybody could give his/her own commentary on whatever major social issue or event was being covered in the article, and they were initially hailed as a promising new avenue for free speech. Unfortunately, as with [=GeoCities=], SturgeonsLaw kicked in -- for every one comment that was reasonably thoughtful and well-written, you generally had to wade through at least nine or ten utterly worthless comments written by trolls, spammers, bigots, religious fanatics, ''anti''-religious fanatics, political extremists on all sides, and all-around raving lunatics, with {{flame war}}s between them breaking out more often than not. Needless to say, this was ''especially'' true when it came to articles related to volatile subjects such as [[UsefulNotes/MisplacedNationalism politics or religion]]; a widespread joke was that the comments sections on such articles could resemble the ramblings on Website/{{Stormfront}}, a prominent white supremacist message board. Comment sections developed such a toxic reputation that "don't read the comments if you value your sanity" became an unofficial motto for many, and a growing number of news websites and internet personalities dispensed with comment sections altogether, while others strongly tightened their moderation and rules in order to regulate what can and cannot be posted in them.
* {{Usenet}} newsgroups have been a cornerstone of the Web since the 80s, and many are still active to this day. However, their relevance began sliding as early as the EternalSeptember of 1993, when America Online opened up Usenet, thus flooding many a group with college freshmen who had no netiquette to speak of. Over time, many forums withered and died as they became overrun with trolls, spammers, and the like. In addition, many of the "alt" groups had begun posting porn or pirated software, thus causing some [=ISPs=] to block off Usenet entirely. Also helping Usenet's demise was the rise of the Website and especially the Web forum, which allowed the same open discussion as a Usenet group, albeit with moderation to keep the {{Garbage Post Kid}}s out.
* vBulletin. Back in the early 00s, this was THE forum script of choice in the internet world. Basically, once you bought a vBulletin license, you knew you had the best possible software and were respected pretty much internet wide for it. And the creators had even better reputation. Then Internet Brands bought it. And released vBulletin 4. And the incredibly poor quality vBulletin 5. The software's popularity dropped sharply off a cliff and never recovered.
* A lot of CMS systems suffered this too. PHP Nuke has basically fallen off the map, Mambo went from a big name to abandoned in a few years and even some of the more 'popular' scripts like Joomla and Drupal have become a lot less popular in recent years, having basically become unknown in large parts of the internet. This was mostly because WordPress went from 'blogging software' to 'quasi CMS with a near monopoly over the market', causing its rivals to pretty much just vanish or die out.
* The MIDI format, even outside of video games, has fallen under this trope (see the [[DeaderThanDisco/VideoGames video game section]] for more information). Back in the mid-late 1990s, [=MIDIs=] were often used as a cheaper and less memory intensive alternative to music. However, by the 2000s to the early tens, with the rise of [=MP3s=] and other sound formats becoming more popular (not to mention more economical, with hard drive sizes increasing and DSL/Cable modems speeding up file transfers), they are now usually subject to mockery.
* Once the king of all website design languages, '''PHP''' has sadly (or finally, depending on your point of view) fallen into this realm in TheNewTens. The exact reasons behind it are very complex and it would take an entire wiki page to chronicle every single factor that contibuted to its falling out of favor, but they can be boiled down to:
** The rise of languages like Javascript, Ruby, Python and ASPX.NET. Unlike PHP, which started as a templating language and later into a full-blown language, these were programming languages first and web development languages second; and such, they were free of many of PHP's quirks and oddities.
** Poor stewardship (a project's quality of management and responsiveness to the community). This was most evident when it stopped development for ''three years'' and the version being developed was ultimately scrapped.
** Many of its proponents moving away from it. Most notably, Facebook decided to develop its own version of PHP, Hack, and called it "all that PHP should've been".
* In the eighties and early nineties, it was a truth universally acknowledged that [=WordPerfect=] would be the dominant player in word-processing software forever. Then, however, Novell bought Word Perfect and seemed interested more in shoehorning [=WordPerfect=] into Novell's networking strategy than in its customers' needs. Additionally, and even worse, [=WordPerfect=]'s main selling points throughout its service life were its key combination based control system, its printer drivers, and its font libraries; the onset of Microsoft Windows effectively killed all three at once. New releases of [=WordPerfect=] were [[ScheduleSlip late]] and [[ObviousBeta buggy]], allowing Microsoft to take over the market.
* Similarly, Lotus 1-2-3 was the dominant spreadsheet program in the '80s and early '90s. It was one of the litmus tests for UsefulNotes/IBMPersonalComputer compatibility, but faltered due to Lotus' slowness in developing a version for Microsoft Windows. This allowed Microsoft Excel to take over and Lotus never recovered. Lotus was eventually gobbled by IBM and not because of their office suite, but because of their actually innovative Lotus Notes corporate mail system.
* Dedicated sound cards like the Sound Blaster have been mostly replaced by generic sound chips built into the motherboard. Like hi-fi sound systems, sound card manufacturers have responded by turning them into professional-grade sound systems with tons of features, such as Surround 5.1 connectors, coaxial and optical SPDIF audio ports, and support for professional sampling rates around the 200 kHz instead of CD-grade 44.1 kHz.
* The idea of paying for operating system upgrades is dead. Apple announced that the latest versions of [[UsefulNotes/AppleMacintosh Mac OS X]] would be free starting with Mavericks, and Microsoft made [[UsefulNotes/MicrosoftWindows Windows 8.1]] a free upgrade from Windows 8, a policy they've carried over to Windows 10. They even announced that it would be a free upgrade from Windows 7. This followed years of decreasing prices for upgrades, around $29 down from around $100 for OS upgrades in the '90s. And that's not counting mobile upgrades, which have always been free.
* The concept that [[VideoReviewShow internet video critics]] could make a living off of ad revenue through third-party video hosting services was popularized when Website/ThatGuyWithTheGlasses was able to successfully implement it in 2008; by 2009 the site was making $150,000 a year off of ad revenue and its creators Creator/DougWalker (who had famously quit his job in 2007 to make web videos full time) and Mike Michaud were named entrepreneurs of the year by ''Entrepreneur'' magazine. However [[GoneHorriblyRight the model became so popular]] that many [[FollowTheLeader copycat sites]] were founded using the same hosting service that TGWTG used (Blip.tv), which caused the formerly lucrative revenue stream to start spreading thin. This was coupled with the rise of ad-blocking programs, which led to companies becoming hesitant to spend money to advertise through Blip, and many started to pull out. Ultimately, Blip's parent Maker Studios had to perform two membership "purges" in 2013 and 2014 and enact stricter standards as to who could use the service, causing the less popular reviewers to migrate to other video hosting platforms, none of which paid out nearly as much as Blip did (if at all). By 2015 the more popular critics remained on Blip, but many had to start supplementing their income through crowdfunding sites like Patreon, while others (like Walker) went to Website/YouTube to gain extra revenue through the partnership program.
** The collapse of the Blip model inadvertently ended up rendering two far more prevalent "doomsday" theories deader than disco. Before 2013, it was generally accepted that the online video critic boom would end one of two ways: either the U.S. government would pass a law (like [[http://en.wikipedia.org/wiki/Stop_Online_Piracy_Act SOPA]]) that would seriously limit the amount of copyrighted content that video makers could show in their videos, or the big entertainment conglomerates would sue video service providers and content makers until they went out of business. That Guy with the Glasses itself was preparing for both options; the site was founded in the first place as a response to the false copyright flagging that Walker had received on [=YouTube=] in early 2008, and several site members testified in front of Congress to protest the passage of SOPA in 2012. Although those fears are still alive in 2015, they're nowhere near as prevalent as they once were - SOPA (and similar follow-up bills) failed to pass in Congress, while many of the big conglomerates ended up going in the opposite direction of what people were expecting and started to embrace online content creators (such as Creator/{{Disney}} who purchased Maker Studios in 2014, much to Walker's amusement).
* Adobe Flash, once the go-to standard for all those fancy animations and videos HTML and [=JavaScript=] just couldn't do, is on its way out. The late Steve Jobs appears to have the last laugh for not including Flash support on iOS, as the mobile-friendly, non-proprietary and less resource-intensive [=HTML5=] becomes the industry standard for "flashy" web design. With each passing day, mobile web browsing becomes less of a chore. Apart from Website/{{Newgrounds}} purists, few appear to mourn its absence as Website/YouTube hands its Flash player the death knell.
* File-sharing, at least for music, has died a slow death. Once legal, inexpensive alternatives like Website/YouTube, iTunes, Pandora, and Spotify emerged, listeners realized that they no longer had to put up with mislabeled files that might possibly be packed with viruses, and readily took advantage of these new services. Today, the same process is affecting file-sharing for TV and film thanks to the rise of services like Creator/{{Netflix}}, Creator/{{Hulu}}, Creator/{{HBO}} Go, and Creator/{{Amazon}}. UsefulNotes/{{Steam}} did the same thing for PC games.
[[/folder]]

[[folder:Fanfiction]]
* ''Fanfic/{{Cupcakes}}''. To the fandom in general, not necessarily because of the fic itself, but its impact. It's often considered the definitive example of how naive the early fans acted. Indeed, the concept of anything dark in Equestria was the entire twist. These days the earliest fanon and memes are seen as embarrassing, this one especially.
* ''Fanfic/DumbledoresArmyAndTheYearOfDarkness'' by Thanfiction was once one of the best-regarded stories in the ''Literature/HarryPotter'' fandom. It provided an intriguing PerspectiveFlip to one of the premiere [[OffscreenMomentOfAwesome offscreen moments of awesome]] in the series, namely the resistance to the Death Eaters by the students of Hogwarts in the final book, and the author gained praise for researching actual ChildSoldiers to better be able to describe the students' plight. The hype, however, was not to last, and criticisms mounted over time, including, but not limited to: the CharacterShilling of Neville as the leader of the resistance to the expense of Luna and Ginny (in the book, Neville himself says they shared leadership duties equally); the treatment of women, particularly the arc involving Lavender being raped and the boys, not Lavender herself, punishing the rapists; the seeming disdain for the canon main characters Harry, Ron, and Hermione, whom various characters insult for not weathering the storm with them; the fact that the story kills off several characters confirmed to survive in canon despite claiming to be canon-compliant; and the [[RonTheDeathEater treatment]] given to Snape, who is shown as an unrepentant Death Eater and the true BigBad of the story -- Thanfiction even stated on his blog that he hated how Snape was redeemed in the books and chose to [[FixFic write him as the sociopath he "really" is]].\\
\\
Any fandom the story had was largely finished off when it came out that "Thanfiction" was actually Andrew Blake, a notorious ConMan who had, under his previous screen name "Victoria Bitter," swindled many ''Literature/LordOfTheRings'' fans out of money, and who is also known for [[BastardBoyfriend seducing and abandoning women in real life]]. The story still has a following, but they are mostly looked at with disdain and willfully blind to the story's flaws.
[[/folder]]

[[folder:Websites]]
* Any number of older {{friending network}}s. Friendster is considered one of the defining examples of a fallen social network (although [[GermansLoveDavidHasselhoff it stayed popular in southeast Asia]] and evolved into a social gaming site), and Website/{{Myspace}} has gone the same way due to competition from (and attempts to [[WereStillRelevantDammit catch up with]]) Website/{{Facebook}}.
* The dot-com boom in the late '90s produced a great many websites and companies that were built seemingly entirely on hype in business journals and kitschy adverts, among them Pets.com, Lycos, and Freeinternet.com. After the bubble burst in 2000-01 and dragged down many e-businesses with it, they went from being the subject of public admiration for their founders' ingenuity and entrepreneurial spirit to mockery for their folly virtually overnight.
** [[http://www.youtube.com/watch?v=ONZFkqzuMjI This]] E-Trade [[SuperBowlSpecial Super Bowl ad]] from 2001 demonstrates the fall from grace that many such companies were undergoing at the time. It's a parody of the CryingIndian ad in which a chimpanzee on horseback wanders past the empty, derelict headquarters of many fallen e-businesses devoted to ridiculous things, plus the abandoned sports car of someone who got rich in the dot-com boom and presumably lost it all when the bubble burst. The chimp sheds a SingleTear upon discovering Pets.com's sock puppet mascot (which had featured in a Super Bowl ad by that company just a year before) lying in the ruins.
* "Mature humor" Flash sites like Website/{{Newgrounds}}, [[http://www.snarkrocket.com/blog-archives/old_cartoons/ Camp Chaos]], and Icebox were seen as the next big thing in the late '90s. At the time, seeing something so independent and uncensored was absolutely phenomenal, especially to younger teenagers, and many of these videos, produced with easily-accessible tools by just one person or a small group of friends, inspired many future animators. Once the millennium hit, though, the popularity of these sites took a downhill slide. Some of them got swept up in the bursting of the dot-com bubble and shut down, while others tried avenues into other forms of media and didn't have much success. Furthermore, as the scope of the Internet grew and their original audience grew up, some people just found their brand of VulgarHumor too juvenile to enjoy anymore, especially with new generations of online videos and websites (such as ''WesternAnimation/HappyTreeFriends'' and Encyclopedia Dramatica) having far surpassed many of these efforts in [[GallowsHumor shock value]], edge, and [[BlackComedy boundary-pushing humor]]. Today, Newgrounds is one of the few sites from that era that's still doing well, and even they [[OldShame have tried to shy away from the tasteless humor that once defined them]], instead mainly showcasing more art-oriented submissions.
* In Wiki/TVTropes, there were once popular features such as FetishFuel, TroperTales, and [[{{Headscratchers}} It Just Bugs Me]], as well as tropes such as I Am Not Making This Up, So Yeah, and [[TrueCompanions Nakama]]. However, as misuse and the like came about, these features and tropes, as well as some others, [[WhyFandomCantHaveNiceThings were]] [[Administrivia/PermanentRedLinkClub deleted]], Administrivia/{{renamed|Tropes}}, or [[ReassignedToAntarctica sent to an offshoot wiki]]. Today, these features and tropes are no longer used, and no matter how much [[BrokenBase some tropers]] will demand to have them returned, the site's admins will not allow any appeal, and instead tropers are encouraged to [[OldShame regard the creation of these features as the worst things that ever happened to the wiki]]. Averted with Wiki/TVTropes itself, [[TemptingFate which will never die]].
* As late as 2007, Website/{{YTMND}} was one of the most powerful forces on the Internet. The day it managed to coordinate a raid among Website/SomethingAwful, Website/FourChan, and Website/{{Newgrounds}} remains one of the most astonishing achievements in trolling history. These days, its Alexa rank barely scratches the top 50,000 sites on the web, and it seems to risk a shutdown every other month. This is largely due to the novelty of a bunch of [=GIFs=] filling up the screen with looping audio having worn off in the wake of sites like Website/YouTube, which offers far more substantial content.
* Related to Website/GeoCities above, dedicated, independent fan pages seem to have gone the way of the dodo. There was a saturation of such pages during the late 1990s, and most of them were pretty much indistinguishable from one another (piles of mundane information about the interest, combined with some poorly-sequenced GIF images and cheesy [=MIDI=] music in the background). The rise in professional media-centered sites like ''[=IGN=]'' and ''The AV Club'', as well as the rise of Website/{{Wikipedia}} (and, of course, this very wiki), made that sort of basic info far easier to access with far less hassle. Fansites now are often very professional, expected to have their own [[TheWikiRule wikis]] and message boards as well as up-to-date news and commentary on the property in question, and more often than not they are closely involved with the creators of said property.
* Digibutter.nerr. Launched as a forum about ''VideoGame/SuperPaperMario'' when the game was new, it gradually faded into irrelevance as the game lost steam, before eventually dying off for good when the owner converted it to a different forum script. Now all that remains are RSS feeds from popular sites and the odd comment from someone who'll never return again.
* A couple of admin sites have come under this as well. AdminFusion for instance was a rather successful site a couple of years ago, but multiple changes in ownership and a complete failure to manage the site have left it a spam ridden ghost town. Similar situations have been noted of Admin Addict and Top Admin, both of which were fairly popular or respected once and are now either shut down or completely dead.
* Digg was a popular social news site, but a poorly-executed redesign caused most of its userbase to flee to Website/{{Reddit}}. It was purchased and relaunched by Betaworks, but is a shell of itself.
* Wiki/{{Uncyclopedia}} is quickly becoming this due to its lack of quality control and the rise of EncyclopediaDramatica, as well as "random" humor having gone completely out of style. It's pretty much only notable for elevating OscarWilde to MemeticBadass status.
** ED itself, though still quite active, hasn't ever really recovered from the attempt to turn it into OhInternet and the subsequent flight of the users to a replacement ED. It's still quite large, but it's not the terrifying bogeyman it once was, now cataloging drama instead of creating it.
* Around 2008 or so '' Website/{{Animexpansion}}'' was a fairly huge and popular site dedicated to (mostly) worksafe anime-related fetish art. Now thanks to myriad hosting/format problems, a failed attempt to turn it into a forum, and the backlash against the site owner due to his [[{{Lolicon}} interests]], the site is dead and nearly gone. Only a tiny fraction of its artists are active in any way.
* Rapidshare was once one of the top 50 sites on the web and was a very widely used file hosting service. After implementing harsh anti-piracy measures, which include heavily capping download speeds for free users back in late 2012, they have lost a significant amount of users. While they have eventually lifted the cap, the damage was already done, and users had moved on to competing services like Mega. In 2015, [[http://torrentfreak.com/file-sharing-icon-rapidshare-shuts-150210/ Rapidshare announced they were shutting down]].
* For most of [[TheOughts the oughts]] and the first couple years of [[TheNewTens the new tens]], [=MapQuest=] was THE website to go for driving directions in the United States. There were competing websites (Rand [=McNally=] and Expedia spring to mind), but none had the popularity and the user-friendliness on which [=MapQuest=] thrived. Around 2012, however, Google Maps began to gain popularity, mainly due to their "Street View" technology. This feature allows users to see actual photos of almost every street and highway in the US, and also gives users the ability to "virtually drive" on the roads using arrows. Needless to say, this made traveling to a location where you've never gone IMMENSELY easier by being able to actually see exactly where you are going before you make the trip. Between the cool features of Google Maps and their [[TheDevTeamThinksOfEverything stunning graphics and extremely user-friendly interface]], they are by far the most popular website for driving directions in 2015, and [=MapQuest=] is barely an afterthought.
* [=SourceForge=] used to be ''the'' place to host free and open source software projects, but eventually lost the title to [=GitHub=]. Even worse, [=SourceForge=] started using its own installer that foists adware on users. This was supposed to be an opt-in feature for projects, but [[ExecutiveMeddling SourceForge did it to the GIMP and Nmap projects' inactive pages without their permission]]. This has severely tarnished its reputation to the point where many techies [[http://www.howtogeek.com/218764/warning-don%E2%80%99t-download-software-from-sourceforge-if-you-can-help-it/ now consider SourceForge a malware site]]. The open source projects still left can't migrate away fast enough.
* {{Website/Fireball20XL}} used to be a major and popular site where numerous comics, dubs, and animations were made near-constantly. But after a bunch of people on Tumblr and Twitter started throwing allegations of abuse and crimes suffered from site creator Bryon "Psyguy" Beaubien, the site's userbase and popularity began slowly drying up. This became worse through a case of TheStreisandEffect when Beaubien threatened legal action towards some of the people who shared their stories about him and tried to hide as much of it as possible through copyright claims against Youtube, leading to hundreds of people reblogging and sharing the post to as many websites as possible. Eventually Beaubien suffered a total CreatorBreakdown and shut down the site and the many domains tied to it. The various other talented creators that worked there are still active and successful, but have disavowed Fireball 20XL and taken their business to other, more reputable sites.
[[/folder]]

[[folder:Web Video]]
* The ''[[Creator/BobChipman Game Overthinker]]'' episode [[http://www.youtube.com/watch?v=iUOA_uhco8I "Who Will Be Remembered?"]] is basically a discussion of this trope, asking which iconic video games and characters will stand the test of time. Past examples from film, animation, comic books and stand-up comedy are employed to demonstrate how the trope works.
** The episode [[http://www.youtube.com/watch?v=jik6K3SQM34 "Thing We Lost in the Fire"]] also covers this trope, talking about how arcades have experienced this in the United States, and how they could possibly [[PopularityPolynomial make a comeback]] (using the ''Golden Tee'' series of golf games as Exhibit A).
** Discussed again in the episode [[http://www.youtube.com/watch?v=rVV7vHiJqps "Setting Sun"]], where he talks about the decline of the Japanese game industry.
* "Tribute" videos on [=YouTube=]. Back in the heyday of 2006-2009, it was common among the younger users to make slideshows/video collages of something, usually a sports team or fictional character, set to a song (usually Music/LinkinPark, Music/GreenDay, Music/SimplePlan, Music/ThreeDaysGrace or similar). Nowadays, with platforms such as Website/{{Tumblr}} where people can blog and discuss such things more extensively, such videos are now considered obsolete or redundant. It didn't help that the videos always had a {{Hatedom}} among the more "mature" users, who found them {{narm}}y and clichéd. An easy way of telling if a [=YouTube=] user was under the age of 17 was by whether or not they had a [[Anime/{{Naruto}} Sasuke]] tribute set to [[Music/ThreeDaysGrace "Animal I Have Become"]] or [[Music/{{Disturbed}} "Down with the Sickness"]] in their uploads.
** Same goes for [[FanVid AMVs]], especially anime ones. Furthermore, the heyday of [=AMVs=] was in the mid-to-late aughts, when Website/YouTube was still fairly permissive when it came to copyright. With [=YouTube=] becoming increasingly litigious in its pursuit of infringers, AMV makers are doubly at-risk -- will they get flagged by a record company, or by the animation company? Consequently, thousands upon thousands of [=AMVs=] have been LostForever and their makers banned since the crackdowns, leaving the practice unappealing.
* WebAnimation/{{Animutation}} was very popular in its day, but its decline coincided with the fall of flash animation (and flash animation websites) and the rise of video-sharing sites like [=YouTube=]. Animutation's reliance on [[SurrealHumor surrealism]] and obscure non-English songs meant that its fan base was never that huge to begin with, and casual viewers abandoned it in favor of the similar, yet more easily-accessible, WebAnimation/YouTubePoop videos when they became popular.
* Text-based video game countdowns (read: Top X lists that make their point across by showing an image or video of the entry followed by a text defending the entry) were huge back in 2008, and people with those videos had views past the 10k mark. From 2010 onwards, however, those type of countdowns have faded out in favor of vocal countdowns (read: Top X list that show video footage while putting in a voice-over defending the entry), and the people that made text-based countdowns in the past are nowadays, for the most part, left in the dust. This can most likely be explained due to the fact that vocal countdowns are easier to follow, more immersive, and easier to put jokes into. Music-based video game countdowns are still generally text-based, but that is mainly because putting a voice-over over music ruins the immersion easily.
** Certain topics in general have become discredited by the community. Most notably the "Top 10 easiest bosses" list. Thanks to the spreading of {{Zero Effort Boss}}es, it has become a rather boring topic to cover.
* MinnesotaBurns used to get video views in the millions, and was getting more and more popular, until a video of him threatening and cursing at a young boy landed him in a lot of trouble. He then turned the channel into a community-based prank channel, but public perception of him was forever tarmished.
* Way back in the early days of [[TheAbridgedSeries Abridged Series]], ''WebVideo/NarutoTheAbridgedSeries'' was perhaps the second most popular series after WebVideo/YuGiOhTheAbridgedSeries. Some went so far as to say that it was the only other good series aside from YGO, and Little Kuriboh would sometimes guest star and take good natured potshots at it in his own series. Eventually, the creators [=MasakoX=] and Vegeta3986 split up and the series ended. Nowadays, its legacy is almost completely forgotten, and its overshadowed by several series that have managed to surpass its early popularity. Evidence of this can perhaps be found in how pitifully short is trope page is compared to many other popular web series.
** A lot of it has to do with their numerous and rather venomous {{take that}}s toward YaoiFangirls and the rampant HoYay (to the point of [[GenderFlip turning a character female]] in order to avoid it), leading to many accusations of homophobia.
* The whole 'reply girl' trend was completely wiped out by the severe backlash the users involved recieved and YouTube retiring the video response function.

* The ''Franchise/StarWars'' vs. ''Franchise/StarTrek'' [[UltimateShowdownOfUltimateDestiny debates]] became this. One of the oldest discussion topics on the internet, it once had its own forum on {{Usenet}}, and countless CrossOver stories were written by the topic. The debate began to falter after various scientifically-oriented fans started crunching numbers, and came to a conclusion suggesting that a lone Star Destroyer [[CurbStompBattle could probably solo the entire Federation fleet]] - to say nothing of the massive disparity in resources between the two traditional sides (the 150-planet Federation is a whole two tiers below the million-planet Empire on the [[AbusingTheKardashevScaleForFunAndProfit Kardashev Scale]]). Debates over the veracity of these calculations were then squashed by official material that [[AscendedFanon provided statistics that were, if anything, higher than the usual claims.]] Since then, any given debate between the two sides tends to [[PowerCreepPowerSeep deliberately ignore the difference,]] analyze unusual situations (''[[Series/StarTrekVoyager Voyager]]'' is replaced by a Star Destroyer, what happens?), or go for humor, with many of the traditional forms having been salted. Any remaining debate was completely driven into the ground by several individuals who tried to turn it into a debate about what was or wasn't canon in the two franchises, which the vast majority of fans simply didn't give a shit about. Most importantly, George Lucas has gone on record by saying that ''Star Wars'' owes part of its success to the path that ''Star Trek'' help pave. Thus, he considers the rivalry absurd. The debate may be seeing something of a resurgence thanks to the more technologically advanced ''Star Trek'' reboot, along with Creator/{{Disney}} disavowing the Franchise/StarWarsExpandedUniverse and all supplementary materials, though it's doubtful that it'll achieve the same fervour as in the late 90s and early 00s.
* Because the lifecycle of a meme is rarely cyclical and often quite rapid, just about any DiscreditedMeme qualifies. Examples include: "I used to be an adventurer like you, then I took an arrow in the knee.", "The Harlem Shake", and many others. As the internet becomes more mainstream and interconnected, the shelf life of memes becomes shorter and shorter. People declared the Harlem Shake a dead meme after less than a month of it gaining prominence.
* Wiki/TFWikiDotNet is well-known for its many running gags. It has a section in its policy page titled "[[http://tfwiki.net/wiki/Transformers_Wiki:Caption#Captions_and_jokes_we.27re_sick_of Captions and jokes we're sick of]]", which lists all of the sites running gags and memes that have died out. Some of said jokes have become so despised by the userbase that mentioning them can get you a revert or even an editing ban if the mods aren't in a good mood.
