What? No More Oprah?

Nothing is set in stone but the most famous daytime TV show in history could soon be coming to an end.

Oprah Winfrey says her contract is due to expire in 2011, which would mark her 25th year on the air, but the talkshow queen says she hasn't decided whether or not she'll continue it.

Industry insiders believe the daily grind may now be too much for her - and also believe she may be interested in taking total control of the cable channel she is launching, the Oprah Winfrey Network (OWN).

Winfrey spokesman Don Halcombe denied a definitive plan exists: "She has not made a decision yet."

This isn't the first time Oprah has thought about leaving her show.

In 1997 and again in 2002, Oprah, one of the richest people in the country, said she considered calling it quits - but both times renewed her contract for several more years.
