I guess I'm not surprised to hear that Oprah Winfrey has been named the most powerful woman in entertainment. You can read the full list here, in The Hollywood Reporter's 17th annual "Women in Entertainment: Power 100" special issue.

OK, here's the thing about this. I really do get why Oprah is powerful. She's in charge of her own show (remember years ago when she fought to gain control and fired a bunch of people?); she's launched a bunch of other shows, including Rachel Ray, Dr. Phil, and maybe Dr. Oz coming up; she opened that school for girls in Africa; people read the books she recommends; they buy the stuff she likes; and she even had a hand in getting Obama into the White House.

On Fortune magazine's annual ranking of the Top 50 Most Powerful Women in Business, Oprah comes in at number 8 (Rich mentioned this, too) and Martha Stewart at number 28. Fortune included Oprah because of her vast empire, including a new satellite radio channel called Oprah & Friends. She was bumped down from number 4 on last year's list. Number one this year is Indra Nooyi, CEO of PepsiCo. I'm not sure how they rank the women, but I think if Oprah told everyone to stop drinking Pepsi, Indra would be in trouble.

And, while Martha's stock is flat and her version of The Apprentice failed, she makes the list because of her big-time partnerships with KB Home, Macy's and Kodak... plus she still has a very successful publishing business.
