YouTube is a video-sharing website, created by three former PayPal employees in February 2005 and owned by Google since late 2006, on which users can upload, view and share videos. The company is based in San Bruno, California, and uses Adobe Flash Video and HTML5 technology to display a wide variety of user-generated video content, including video clips, TV clips, and music videos, and amateur content such as video blogging, short original videos, and educational videos.
Most of the content on YouTube has been uploaded by individuals, but media corporations including CBS, the BBC, Vevo, Hulu, and other organizations offer some of their material via YouTube, as part of the YouTube partnership program. Unregistered users can watch videos, and registered users can upload an unlimited number of videos. Videos considered to contain potentially offensive content are available only to registered users affirming themselves to be at least 18 years old. YouTube, LLC was bought by Google for US$1.65 billion in November 2006 and now operates as a Google subsidiary.
