Current TV is like youtube, but on television. It's user generated, there are editors who choose what goes on air but mostly people vote for what they want to see and it's a pretty unique experiment. It's founded by Al Gore (the man who invented the Internet then redeemed himself by saving the planet through his excellent documentary "An Inconvenient Truth" - which I cannot stop recommending to any living being unfortunate enough to cross my path).
Current TV is coming to the UK through BSkyB next spring says the Sunday Times. Another bastion of old media falling under users' control.
