Why is Oprah going to cable? Hint: It's nothing to get teary about


Oprah Winfrey is a smart cookie. I am guessing she knows all too well that you can make more money in cable than you can on a TV network. If it's like other cable networks, her new Oprah Winfrey Network (OWN), which she co-owns with Discovery Communications (DISCA), will be much more profitable than the TV networks.

And her departure from her popular show will cost those TV networks big money. How much? Show broadcaster, Walt Disney's (DIS) ABC, will lose millions in ad revenues, according to the New York Times. CBS Corp. (CBS), which owns Oprah's syndication rights, will similarly lose millions.
