Daytime diva takes to the air

XM Radio chief exec Hugh Panero and poet Maya Angelou joined Oprah Winfrey on the floor of the Nasdaq Exchange on Monday to ring the opening bell on the stock market.

Later the talk queen flipped the switch on her new XM Satellite Radio channel “Oprah & Friends.”

Channel went live as Winfrey pressed a red button in the Rainbow Room at 30 Rock, where she had gathered the “friends,” including best friend Gayle King, designer Nate Berkus, financial expert Jean Chatzky, cardiologist Dr. Mehmet Oz, fitness coach Bob Greene, psychologist Robin Smith and author Marianne Williamson.

Channel reps the first product of Harpo Radio, the latest addition to Winfrey’s ever-expanding media empire, which includes Harpo Prods., Harpo Print, Harpo Films and Harpo Inc.

Each of Winfrey’s “friends” will get a show on the new channel, including poet Angelou. Winfrey’s on-air contribution will be limited to a weekly hourlong conversation with King, “The Oprah & Gayle Show.”
