The final episode scored a 13.3 household rating in the nation's metered markets, the Nielson Co. said Thursday.
That number was the highest since February 1994, when an "/*Oprah*/" episode called "People Shed Their Disguises" got a 13.4 rating.
Metered market ratings measure roughly half the nation 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. Tuesday's episode got a 10.7.
