Justin TV

"Justin.tv, founded in San Francisco by Justin Kan, is a network of diverse channels providing a platform for lifecasting and live video streaming of events online. The original Justin.tv was a single channel that evolved into the Justin.tv network of thousands of diverse channels."
That's from Wikipedia.
And I am watching this site for few months now and has become my most visited site. They life cast all football matches as well as latest movies. But one question is "Can they survive for Copy Right thing?"
And here is the link to their web site, if you interested http://www.justin.tv/ .
