Winfrey ready to launch travel show

Daytime superstar Oprah Winfrey will be moving to nighttime to host a show on her new cable channel.

The network announced that the hourlong show, Oprah's Next Chapter, will release her from the studio and her longtime talk-show format for conversations and travel around the world.

The show is expected to be a key ingredient of the Oprah Winfrey Network, and guarantees Winfrey will regularly appear on the 24-hour network she'll be largely programming from behind the scenes.

A joint venture of Winfrey's Harpo and Discovery Communications, the network is expected to reach 80 million homes.

Winfrey will end her weekday syndicated talk show at the close of its 25th season in late 2011.
