Oprah's half-sister reveal boosts series to highest ratings in nearly 6 years
Winfrey's special episode, in which she meets with the half-sister she went decades without knowing she had, averaged a 9.6 household rating.
Her series hasn't boasted a number that high since her post-Oscar broadcast from the Kodak Theatre in Feb, 2005.
Though she still beats a lot of her daytime competition, Winfrey's declining ratings have been widely publicized going into her final season. So this probably feels pretty good.
