When You Tube was launched in 2005, it was possible to upload longer videos, but a ten-minute limit was introduced in March 2006 after You Tube found that the majority of videos exceeding this length were unauthorized uploads of television shows and films.
Most of the content on You Tube is uploaded by individuals, but media corporations including CBS, the BBC, Vevo, and Hulu offer some of their material via You Tube as part of the You Tube partnership program.
Unregistered users can only watch videos on the site, while registered users are permitted to upload an unlimited number of videos and add comments to videos.
Such captioning is usually not perfectly accurate, so You Tube provides several options for manually entering the captions for greater accuracy.
You Tube accepts videos that are uploaded in most container formats, including AVI, MP4, MPEG-PS, Quick Time File Format and FLV.
According to You Tube, this was the first worldwide free online broadcast of a major sporting event.
