Apple board member and ex-US politician Al Gore has launched a TV channel aimed at the young.

Current is a cable TV channel that will target viewers aged between 18 and 34 with a blend of news, culture and viewer-produced video, writes Associated Press.

Gore said the venture is dedicated to giving young people a voice. "We're about empowering this generation to engage in the dialogue of democracy and tell the story of what's going on in their lives in the dominant media of our time," he told investors at the launch.

Central to the strategy is the idea that Current's viewers will supply their own video content, and there are editing tools available on the Current Web site that will help them do so. The plan is that eventually that amateur video will comprise more that half the programming on the channel.

Gore described his frustration that television, because of the high cost of cameras, studios and production, had long been a "one-way" medium dominated by large media companies. But in recent years this has changed. He explained: "Innovations in digital video have put those tools in the hands of young people.

"The $100,000 television camera has become a $3,000 high-definition camera, and the $250,000 editing console has become a $1,000 Apple computer program. The five-person crew can be one young woman in her twenties with something the size of a handbag."

The channel will launch on August 1. It will remain privately financed and will initially be available in 19 million cable-subscriber homes in the US.

Gore insisted that Current will have no political agenda.
