You Tube is an American video-sharing website headquartered in San Bruno, California, United States.
Available content includes video clips, TV show clips, music videos, audio recordings, movie trailers, and other content such as video blogging, short original videos, and educational videos.
Most of the content on You Tube has been uploaded by individuals, but media corporations including CBS, the BBC, Vevo, Hulu, and other organizations offer some of their material via You Tube, as part of the You Tube partnership program.
Unregistered users can watch videos, and registered users are permitted to upload an unlimited number of videos and add comments to videos.
Videos deemed potentially offensive are available only to registered users affirming themselves to be at least 18 years old.
In July 2016, the website was ranked as the second most popular site by Alexa Internet, a web traffic analysis company.
