The Oprah Winfrey Network announced today that Peter Liguori has been named interim Chief Executive Officer of the network, replacing Christina Norman, who helped to launch the cabler in January. Liguori will oversee the struggling network while continuing to serve as chief operating officer for Discovery Communications.

The shakeup comes at a time when the fledging cabler is struggling to find an audience. Since its launch, the network has only averaged 283,000 viewers in prime time. Not suprisingly, one of the most watched shows on OWN is Oprah Behind the Scenes, which lures 382,000 viewers.

The network has more original programming rolling out in the next year, including the October debut of Rosie O’Donnell’s new talk show Rosie and the launch of Oprah’s Next Chapter in 2012.

Before joining Discovery in 2009, Liguori was the president of entertainment for Fox.
