Internet TV channels

I'm going to start compiling a list of internet TV channels - starting with ManiaTV, about which PC world reports "you can submit your own 5-minute video clip; if it's picked, the site will devote an hour of programming to a video of your life. You can also send in clips from your mobile phone, or program an hour-long "mixtape" of your favorite video clips for broadcast online. This self-styled MTV (without the TV) claims 1 million unique visitors a month."
