Yahoo! Inc. and Current TV, a "viewer created content" TV channel, have teamed up to launch the Yahoo! Current Network.

The new online channel combines user-generated videos and professional clips in a co-branded environment. The site is free and ad-supported.

"Current TV empowers young adults to actively participate in creating the television they want to watch, but in a broader sense; we're about giving young adults a voice," states Current TV co-founder and chairman Al Gore. "Current's mission has always been to spark a global conversation among young adults. Partnering with Yahoo helps us advance this mission."

The Yahoo Current Network debuts with four channels on Yahoo Video.

"The new Yahoo Current Network helps publishers find an audience and be discovered on the biggest network on the planet," says Dan Rosensweig, chief operating officer for Yahoo. "In addition, the Yahoo Current Network allows advertisers to reach highly-targeted audiences in an engaging environment."
