* The runaway success of ''Website/TheBestPageInTheUniverse'' back in the late 90s spawned a whole genre of websites that follow the pattern of, "I run an angry blog where I write offensive things". Many even went as far as to title their pages akin the original with examples like, "''The '''Second''' Best Page in the Universe''", or even, "''The '''Worst''' Page in the Universe''". Most imitators unfortunately ignored the original website's satirical edge and instead just aimed for shock value.
* In that vein, ''Website/TheAgonyBooth'' re-tailored their site in the early tens to emulate Website/ThatGuyWithTheGlasses, supplementing their old text reviews with "prop comic" reviewers and videos. Most of these were received with lukewarm responses at best. Unfortunately the long-form recaps that had been the site's signature and unique appeal were completely abandoned to make room. The majority of the new critics were [[WebVideo/TheSpoonyExperiment Spoony Experiment]] knock-offs who used to advertise on his forum and on YouTube before being picked up. A similar website, Reviewtopia, was lambasted for trying to copy the success of TGWTG, and most of those critics were absorbed into the TGWTG mothership within a few months. The "success" of WebVideo/TheBlockbusterBuster and Oancitizen came about because of this.
* Stories based on the TheSlenderManMythos have become increasingly popular due to the success of Blog/JustAnotherFool (blog) and WebVideo/MarbleHornets (video series). Some recent cases have abandoned the idea of the characters going in blind and actually mention the existing blogs, with the protagonists assuming ([[RealAfterAll wrongly]]) that they're just an urban legend.
* WebAnimation/ASDFMovie has had dozens of remakes in real life, LEGO, VideoGame/MineCraft, VideoGame/HappyWheels, VideoGame/ModernWarfare3, VideoGame/GarrysMod, Black Ops 2, SFM and so on. They all play the audio of one or more of the original videos over their own animation and meet varying success. There are also a dozen YouTube Poops and even fan made sequels.
* Reviews were commonplace, but WebVideo/TheAngryVideoGameNerd and WebVideo/TheNostalgiaCritic started the trend of [[PlayedForLaughs funny ones.]] They have since achieved online notoriety and several others attempting a style similar to them (i.e. that of a foul-mouthed and pissed off reviewer of old crappy games and/or films). It's worth noting that the Angry Video Game Nerd himself was far from being the first to do this. {{Seanbaby}} had done this years before (and was likely an inspiration), and he may not have been the first himself.
** Unfortunately, because of his [[FanDumb rabid fanbase]], those who actually try something new with the idea or take an alternate approach are often ignored or flamed for being "rip-offs". Even people who review ANYTHING made in the 80s such as cartoons and comics (just look at WebVideo/TheNostalgiaCritic) get branded as rip-offs. Many hold the opinion that some of his genuine ripoffs are better than Mr. Rolfe himself is anyway, so to some this is a moot point.
*** Speaking of the Critic, the fact that he got branded as a rip-off was the reason why his feud with the Nerd started in the first place (see Nerd Rant 1 for proof). Ironically, a lot of contributors on Website/ThatGuyWithTheGlasses have copied the Critic's style, down to even the camera standpoints and way of executing gags.
** Also, [[WebVideo/AtopTheFourthWall Linkara]] was one of the first with a plotline, and now it's commonplace on Website/ThatGuyWithTheGlasses.
** You can find MILLIONS of amateurs with a webcam ranting about stuff they hate nowadays.
** It is often cited that the ongoing storylines of these shows are what inspired MovieBob to do the same with The Game Overthinker.
** The ''WebVideo/GameGrumps'' review of ''[[https://www.youtube.com/watch?v=u-LfKbCR0MI Mickey Mousecapade]]'' has Arin noting how many reviewers out there try to emulate the nerd's style with varying (though usually low) levels of success. He spends the entire episode doing a [[StylisticSuck hilariously and intentionally bad]] imitation of the nerd while Danny pretty much spends the entire episode [[{{Corpsing}} in pain laughing]].
* WebVideo/{{Oancitizen}} has often been accused of being a rip-off of WebVideo/TheCinemaSnob, despite the fact that Oancitizen reviews arthouse films without being snobbish while the Cinema Snob reviews exploitation movies while pretending to be a snobbish critic.
* ''WebVideo/YuGiOhTheAbridgedSeries'' has had many knockoffs. The creator has even done voices for some of them, as well as [[LampshadeHanging lampshading]] it in his own series, by turning the "Multiply" spell card (which makes copies of Kuriboh) into "Creator/LittleKuriboh Impersonators". Yami activates it in his duel against Pegasus.
-->'''Pegasus:''' There's so many of them! I can't tell which one is the original!\\
'''Yami:''' That's right, and that means you'll never be able to watch the Abridged Series ever again!\\
'''Pegasus:''' [[BigNo NOOOOO]]! I can't live without ''WebVideo/YuGiOhTheAbridgedSeries''! It's ''so'' important to me!\\
'''Yami:''' Don't worry, Pegasus. There's always ''WebVideo/NarutoTheAbridgedSeries'', [[TakeThat but we all know that's not quite as good]]!
** The joke also applies to how many people were literally just titling their video "Abridged series episode ''x''" and weren't trying to be Littlekuriboh, but were just being bait-and-switch trolls.
* ''WebVideo/AMVHell''. Though the format likely started with WesternAnimation/RobotChicken, it was AMV Hell that defined it as a Youtube staple and fan work in general, with notable entries like ''Machinima/TheGModIdiotBox'' and ''[[WesternAnimation/MyLittlePonyFriendshipIsMagic PONIES:]] [[http://www.youtube.com/watch?v=2Tjb14VoWjg The Anthology]]''.
* After Franchesca Ramsey made the [[http://www.youtube.com/watch?v=ylPUzxpIBe0 Shit White Girls Say...to Black Girls]] video, many others followed up with videos following a similar format of a marginalized person performing as a privileged person saying ignorant and bigoted remarks to a person of their marginalization.
** That video was in turn inspired by the video [[http://www.youtube.com/watch?v=u-yLGIH7W9Y "Shit Girls Say"]], based on a Twitter page, which also had various imitators with black girls, Spanish girls, etc.
* Once the [[http://apersonificationofgreed.tumblr.com/ Greed]] blog was created, others soon made [[SevenDeadlySins Sins]] blogs in the style of the first, and the [[SevenHeavenlyVirtues Virtues]] soon followed in the [[{{Personifications}} Personification]] subfandom.
* After LetsPlay/{{Chuggaaconroy}} put LetsPlay-ing into the mainstream with his wacky {{Manchild}} antics, loud moments, and {{Epic Fail}}s, a spat of other [=YouTube=]rs trying to find the same success imitating this style without any of the approachable personality or passion Chuggaa puts into his videos. If anything, this following also led to WebVideo/{{Retsupurae}} poking fun at these pale imitations. Ironically, Chuggaa himself has stated that his inspired by LetsPlay/ProtonJon.
* [[BenDrowned Ben Drowned]]. It is the most famous gaming [[CreepyPasta Creepy Pasta]] that was filled with horror, great effects, and a great story. It was so popular, that we got many other gaming horror stories like [[SonicExe Sonic.exe]], Megaman's Ladder, I Hate You, and many more stories that don't even come close to capturing the atmosphere nor the creep factor that Ben Drowned had. Blank cartridges or discs with handwritten titles on them (which were free, of course. Even at brick and mortar stores.), friends who mysteriously disappeared in the context of the story, spooky save file shenanigans, and simplistic romhack footage on YouTube are some of the elements that label them as derivative.
* The popularity and critical acclaim of ''WebVideo/TheLizzieBennetDiaries'' inspired a wave of video blog adaptations of other classic literature including ''WebVideo/TheAutobiographyOfJaneEyre'', ''Classic Alice'', and ''Nothing Much to Do''.
* LetsPlay/{{Markiplier}} seems to follow the LetsPlay/PewDiePie formula of ADVERTISING VIDEOS IN ALL CAPS, photoshopped title cards, and OTT panicking at survival horror games. Over time, he's even adopted Pewd's charity work, haircut and five o'clock stubble, as well. Amazing.
* WebVideo/CinemaSins has seen ''dozens'' of imitators on YouTube, from single videos to long-running channels reviewing different kinds of visual media. Two of the earliest examples -- WebVideo/GameCareNetwork and WebVideo/{{Dartigan}}, both video game reviewers -- now have their own pages.
* The runaway success of both ''WebVideo/GameTheory'' and ''WebVideo/VSauce'' have inspired many other youtube channels to create their own scientific analysis and WildMassGuessing of pop culture works be it video games, movies, TV shows, or even internet stars. Some like the WebVideo/SuperCarlinBrothers have taken it even further combining the pop-culture hypothesizing of ''Game Theory'' with the vlog format of the ''WebVideo/VlogBrothers''.
* While doing [[AlexDay Alex Reads Twilight]], Alex repeatedly insisted he would not be doing the rest of the ''Literature/{{Twilight}}'' series. This spawned a host of imitators that picked up with the second book in the series, ''NewMoon'', copying his general man-in-front-of-a-camera-summarises-and-snarkes-about-a-book style.
