Al Gore’s Current TV is collaborating with Yahoo. Inc to create four new broadband channels which launched on Wednesday, with a video of U2’s last concert tour.

The online service which is called the Yahoo Current Network, will be available within the portal’s main video category, working as a combination of user submitted videos as well as studio-produced content, most of which will accessible only online.

The broadband channels will focus on disseminating videos by young viewers but will also focus on a range of different topics such as action sport news, automotives and adventure travelling as well as one of the channels showcasing “the best of what’s buzzing around the world and web”.

The joint enterprise promises to increase Current TV’s visibility. At present, it is available in 30 million of the 110 million US homes with televisions.

“The distribution reach and community of online viewers that Yahoo serves gives an unparalleled opportunity to connect the online video experience, including video-related content, with a mass audience,” Gore told the Associated Press.

There are four more Yahoo! Current channels expected to be added by the end of next year.
