Oprah Winfrey is shaking things up at OWN.

The network, which launched in January, hasn't been performing as well as the talk show host had hoped, and the New York Post reports that network brass have been shaking things up behind the scenes.

"We're doing a lot of changes to the schedule," a spokesman for OWN told the Post yesterday. First up: moving OWN's highest-performing show, 'Season 25: Oprah Behind the Scenes,' to Sunday nights.

The "reboot" will focus on celebrity reality shows, with 'Behind the Scenes' anchoring the new schedule. There will also be another advertising push.
