It began with three friends searching for an easier way to share videos. One - Jawed Karim - uploaded the site's first clip - a movie of himself dressed in an anorak at San Diego Zoo. By the end of its first year YouTube was broadcasting 25 million videos a day and it was soon bought by the internet giant Google. In 2010 24 hours of video are now uploaded every minute. The site's also become an important political tool - almost a million people watched a wounded girl dying during protests in Iran in July 2009.
