YouTube is a video-sharing website on which users can upload, share and view videos. It is the third most visited website according to Alexa, after Google and Facebook. It was created by three former PayPal employees in February 2005, Chad Hurley, Steve Chen and Jawed Karim. Hurley studied design at Indiana University of Pennsylvania and Chen and Karim both studied computer science at the University of Illinois. The idea of creating YouTube have a lot of varying speculations. One which is very famous is that Hurley and Chen had experienced difficulty sharing videos shot at a dinner party at Chen's San Francisco apartment due to email attachments limitations. That's when the idea about YouTube originally sparked. Another speculation is that YouTube started out as a dating site dubbed “Tune In Hook Up”. The domain name YouTube.com was activated on February 14, 2005. After the launch the founders had to struggle for finances. In November 2005, however, a lot of people and companies have invested large sums of money to keep YouTube running. In its initial operation, the site was flooded by an overwhelming number of videos uploaded on a daily basis. On November 9, 2006 YouTube was purchased by Google for US$1.65 billion in stock.
