A viral video is one that becomes popular through the process of Internet sharing, typically through video sharing websites, social media and email.Viral videos often contain humorous content and include televised comedy sketches, such as The Lonely Island's "Lazy Sunday" and "Dick in a Box", amateur video clips like Star Wars Kid the 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 . More recently the video by Invisible Children, Inc. named Kony 2012, which gained critical acclaim worldwide, became the most viral video in history with over 32,000,000 views within its first week since its upload on 05 March 2012 and has been viewed more than 88,000,000 times as of 20 April 2012.
With the proliferation of camera phones,many videos are being shot by amateurs on these devices. The availability of inexpensive video editing and publishing tools allows video shot on mobile phones to be edited and distributed virally, by email or website, and between phones by Bluetooth or MMS. These consumer-shot videos are typically non-commercial, intended for viewing by friends or family. A video becoming viral is often unexpected, and an accident, and therefore a video cannot be called viral purely in the creator's intention at the time of recording.
