YouTube just turned eight-years-old and the social networking video site keeps growing. YouTube users now upload 100 hours of video every minute (that's over four days of new video each minute!), up from 72 hours per minute this time last year (and 48 hours per minute in 2011.)
Over 1 billion people visit YouTube monthly, which amounts to almost one out of every two people on the Internet.
