Today’s episode of The Oprah Winfrey Show marks the beginning of the gab guru’s long goodbye. Her show will end in 2011, after a quarter of a century on the air at CBS. “Twenty five years feels right in my bones and right in my spirit,” Winfrey told her audience in Chicago this morning. “It is the exact right time.” But the media maven isn’t retreating from the spotlight – she plans on expanding her empire by creating her own cable channel, The Oprah Winfrey Network. Rumour has it, Winfrey will have a new talk show. Even better, she’ll OWN it.
