When a video goes viral, YouTube is typically the driving force. As of 2011, YouTube is the third-ranked website globally, with hundreds of millions of users. While you might be using YouTube only to look up video of cute cats and funny pranks, other users actually generate a profit stream ranging from pocket money to money in the bank using their personal YouTube channels and the videos they create. If you want in on the YouTube gravy train, the first thing you should know is that it's not as easy as it may look.
YouTube allows users to upload, view, rate, share, add to favorites, report, comment on videos, and subscribe to other users. It offers a wide variety of user-generated and corporate media videos. Available content includes video clips, TV show clips, music videos, short and documentary films, audio recordings, movie trailers, live streams, and other content such as video blogging, short original videos, and educational videos. Most of the content on YouTube is uploaded by individuals, but media corporations including CBS, the BBC, Vevo, and Hulu offer some of their material via YouTube as part of the YouTube 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. Videos deemed potentially inappropriate are available only to registered users affirming themselves to be at least 18 years old.
