moved to websites, several of which were based on user-generated content, including Wikipedia (2001) and Flickr (2004). User-generated Internet video was popularized by YouTube, an online video platform founded by Chad Hurley, Jawed Karim and Steve Chen in April 2005. It enabled the video streaming of MPEG-4 AVC (H.264) user-generated content from anywhere on the World Wide Web. The BBC set up a pilot user-generated content team in April 2005 with 3 staff. In the wake of the 7 July 2005 London bombings and the Buncefield oil depot fire, the team was made permanent and was expanded, reflecting the arrival in the mainstream of the citizen journalist. After the Buncefield disaster the BBC received over 5,000 photos from viewers. The BBC does not normally pay for content generated by its viewers. In 2006 CNN launched CNN iReport, a project designed to bring user-generated news content to CNN. Its rival Fox News Channel launched its project to bring in user-generated news, similarly titled "uReport". This was typical of major television news organizations in 2005–2006, who realized, particularly in the wake of the London 7 July bombings, that citizen journalism could now become a significant part of broadcast news. Sky News, for example, regularly solicits for photographs and video from its viewers. User-generated content was featured in Time magazine's 2006 Person of the Year, in which the person of the year was "you", meaning all of the people who contribute to user-generated media, including YouTube, Wikipedia and MySpace. A precursor to user-generated content uploaded on YouTube was America's Funniest Home Videos. Motivation for creating UGC The benefits derived from user-generated content for the content host are clear, these include a low-cost promotion, positive impact on product sales, and fresh content. However, the benefit to the contributor is less direct. There are various theories behind the motivation for contributing user-generated content, ranging from altruistic, to social, to materialistic. Due to the high value of user-generated content, many sites use incentives to encourage their generation. These incentives can be generally categorized into implicit incentives and explicit incentives. Sometimes, users are also given monetary incentives to encourage them to create captivating and inspiring UGC. Implicit incentives: These incentives are not based on anything tangible. Social incentives are the most common form of implicit incentives. These incentives allow the user to feel good as an active member of the community. These can include the relationship between
