What will daytime television do without its queen? The president of Harpo Inc., Oprah Winfrey's production company, has announced that the woman with the gift of gab will share with viewers on Friday the decision to discontinue what has been a daytime staple for 25 seasons, The Oprah Winfrey Show. The program turned Oprah into a household name, and stands as the most successful syndicated talk program, reaching 7 million viewers daily The last episode is scheduled to air September 9, 2011. "Oprah’s personal comments about this on tomorrow’s live show will mark an historic television moment that we will all be talking about for years to come," Harpo's president wrote. Oprah will concentrate on her cable network, OWN, which she is starting with Discovery Communications and will debut in January 2011. Oprah will appear on-air and have a behind-the-scenes role at her new home. The network hasn't commented, but Oprah is expected to have a daily show, though one that's different from the one she has now.
