The finale The Oprah Winfrey Show airs Wednesday, May 25.
How high might the viewership reach?
To assist your guess, Monday's Oprah episode drew a 10.0 household rating, which I'll back of the envelope in the neighborhood of 14 million average viewers. (Compared to recent weekly Oprah averages of around 7 million viewers).
What's your guess?
Update: Metered market overnights give the show a 13.3 household rating. My back of the envelope ballpark viewership is in the 17-18 million viewer range (pending the official viewership numbers from Nielsen). Readers were a bit optimistic.
