MTV is launching a free "channel" on the internet that will show some of the station's TV programmes, including reality hit The Osbournes.
The Osbournes is one of MTV's best-known shows
The MTV Overdrive website will let users with high-speed computer connections watch music videos and extended programmes on demand.
The website is currently being tested and will launch fully on 25 April.
Other companies, including Walt Disney and Microsoft, already provide content for online viewers.
Jason Hirschhorn, MTV's senior vice president of digital music and media, said the channel was being launched in response to the high number of young fans with broadband.
"It seemed essential to create a new hybrid screen with its own content," he said.
Music videos, live performances, film trailers and programmes about video gaming and fashion are expected to be on the new service.
MTV president Van Toffler has said he is not worried about the web service drawing viewers away from their existing TV channels.
"The TV experience is still great," he said. "Our ratings are moving higher and we don't fear that."
He added that MTV was in talks with cable providers to deliver the new service to cable subscribers, but a deal has yet to reached.
