As OWN was under development, Winfrey said she was also trying to finish the last 130 episodes of her syndicated TV talk show, the last episode of which aired on May 25. With "The Oprah Winfrey Show" out of the way, Winfrey said she can be "all in" at OWN. "I now have the time to be committed to the nurturing of this network," Winfrey said in an interview with Paula Zahn at a cable industry trade show in Chicago.

"The vacation I thought I was going to have is kind of over... at least for the time being." Rosie O'Donnell, Shania Twain, Sarah Ferguson and Winfrey friend Gayle King have first-season shows on the commercially-supported OWN, which offers a mix of talk and reality shows, films and original documentaries.

Winfrey will appear in "Oprah's Next Chapter," in which she travels the world in search of interesting stories, and "Season 25: Oprah Behind the Scenes," a chronicle of her final talk show year.
