The Associated Press has confirmed that Oprah Winfrey’s final farewell episode scored its highest audience in 17 years. The Nielson Co. reports that the final episode delivered a 13.3 household rating in the nation’s metered markets. That’s the highest number since February of 1994 when she did an episode called “People Shed Their Disguises” (sidebar: I don’t even remember that show). A viewer count for the “Oprah” finale won’t be available from Nielsen for two weeks.
