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, logics that explain why sharing has become such common practice, not just how. Viral videos may be serious, and some are deeply emotional, but many more are centered on entertainment and humorous content. They may 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
