Oprah Winfrey's production company says Winfrey will announce Friday that her talk show will end in 2011 after its 25th season on the air.
Chicago-based Harpo Productions Inc. said Thursday night that the talk show host will give more details live on the The Oprah Winfrey Show broadcast Friday.
Winfrey started her broadcasting career in Nashville, Tenn., and Baltimore, Md., before relocating to Chicago in 1984 to host WLS-TV's morning talk show A.M. Chicago.
That show was renamed The Oprah Winfrey Show in 1985. A year later, Winfrey established Harpo and her talk show went into syndication. In 1990, Winfrey opened Harpo Studios in Chicago's West Loop neighborhood.
