Seeking celebrity online

Daytime superstar Oprah has launched her own channel on YouTube, reports Variety.

The Oprah Channel will host previews of coming episodes, behind-the-scenes footage and other material. Winfrey will take some level of hands-on interaction to the channel, selecting favorite videos for the channel's front page.

The initiative goes the other direction as well. The popular TV host will interview YouTube founders Chad Hurley and Steve Chen on a coming episode of her show. Characters from popular YouTube videos will also appear on the show.

While the channel is positioned by Harpo Productions as a great way to interact with fans, comments on the videos are being moderated carefully.
