24/7 programming now available on 'Oprah Radio'

Oprah Winfrey has expanded to round-the-clock programming on her Sirius XM satellite radio station and has changed its name from "Oprah & Friends" to "Oprah Radio."

Harpo Radio Inc. and Sirius XM Radio Inc. announced the changes Friday. Winfrey signed a $55 million, three-year deal with XM Satellite Radio Holdings Inc. effective September 2006. Since then, Sirius and XM satellite radio stations have merged.

The new station launched Wednesday and now includes new shows like the "O Magazine Show," ''Better in Bed" with sex therapist Dr. Laura Berman and "The Oprah Book Club." They join radio shows hosted by personalities that appear on "The Oprah Winfrey Show," including Gayle King, Dr. Mehmet Oz and fitness expert Bob Greene.
