A viral video is a video that becomes popular through a viral process of Internet sharing, typically through video sharing websites such as YouTube as well as social media and email. For a video to be shareable or spreadable, it must focus on the social logics and cultural practices that have enabled and popularized these new platforms.
Viral videos may be serious, and some are deeply emotional, but many more are centered on entertainment and humorous content. Notable early examples include televised comedy sketches, such as The Lonely Islands "Lazy Sunday" and "Dick in a Box", Numa Numa videos, The Evolution of Dance, Chocolate Rain on YouTube; and web-only productions such as I Got a Crush... on Obama. Some eyewitness events have also been caught on video and have "gone viral" such as the Battle at Kruger.
One commentator called the Kony 2012 video the most viral video in history (about 34,000,000 views in three days and 100,000,000 views in six days), but "Gangnam Style" (2012) received one billion views in five months and was the most viewed video on YouTube from 2012 until "Despacito" (2017).
History
Videos were shared long before YouTube or even the Internet by word-of-mouth, film festivals, VHS tapes, and even to fill time gaps during the early days of cable. Perhaps the earliest was Reefer Madness, a 1936 "educational" film that circulated under several different titles. It was rediscovered by Keith Stroup, founder of NORML, who circulated prints of the film around college film festivals in the 1970s. The company who produced the prints, New Line Cinema, was so successful they began producing their own films. The most controversial was perhaps a clip from a newscast from Portland, Oregon in November 1970. In the clip, the disposal of a beached whale carcass by dynamite is documented, including the horrific aftermath of falling mist and chunks since the exclusion zone was not big enough. The exploding whale story obtained urban legend status in the Northwest and gained new interest in 1990 after Dave Barry wrote a humorous column about the event, leading to copies being distributed over bulletin board systems around 1994.
The "humorous home movie" genre dates back at least to 1963, when the TV series "Your Funny, Funny Films" debuted. The series showcased amusing film clips, mostly shot on 8mm equipment by amateurs. The idea was revived in 1989 with America's Funniest Home Videos, a series described by an ABC executive as a one-time "reality-based filler special" that was inspired by a segment of a Japanese variety show, Fun With Ken and Kaito Chan, borrowing clips from various Japanese home video shows as well. Now the longest-running primetime entertainment show in the history of ABC, the show's format includes showing clips of home videos sent in to the show's committee, and then the clips are voted on by a live filmed audience, with the winners awarded a monetary prize.
During the internet's public infancy, the 1996 Seinfeld episode "The Little Kicks" addresses the distribution of a viral video through non-online, non-broadcast means. It concludes with the citizens of New York City having individually witnessed Elaine's terrible dancing via a bootleg copy of a feature film, establishing that the dancing footage had effectively gone viral.
Viral videos began circulating as animated GIFs small enough to be uploaded to websites over dial-up Internet access or through email as attachments in the early 1990s. Videos were also spread on message boards, P2P file sharing sites, and even coverage from mainstream news networks on television. Two of the most successful viral videos of the early internet era were "The Spirit of Christmas" and "Dancing Baby". "The Spirit of Christmas" surfaced in 1995, spread through bootleg copies on VHS and on the internet, as well as an AVI file on the PlayStation game disc for Tiger Woods 99, later leading to a recall. The popularity of the videos led to the creation of the television series South Park after it was picked up by Comedy Central. "Dancing Baby", a 3D-rendered dancing baby video made in 1996 by the creators of Character Studio for 3D Studio MAX, became something of a mid-late 1990s cultural icon in part due to its exposure on worldwide commercials, editorials about Character Studio, and the popular television series Ally McBeal. The video may have first spread when Ron Lussier, the animator who cleaned up the raw animation, began passing the video around his workplace, LucasArts.
