Oprah Winfrey's farewell scores high

Preliminary figures show Wednesday's finale of The Oprah Winfrey Show scored its highest audience in 17 years. The Nielsen Co said on Thursday that the final episode delivered a 13.3 household rating in the US' metered markets. It was the highest number since February 1994. That's when an Oprah episode called People Shed Their Disguises got a 13.4 rating. Metered market ratings measure roughly half the US and can't be translated into audience figures. A viewer count for the Oprah finale won't be available from Nielsen for two weeks. The metered market rating for Monday's surprise farewell episode of Oprah logged a 10.2. Nielsen said Tuesday's episode got a 10.7.
