Fast National ratings for Thursday, July 23, 2009.

Was it a Katie Holmes bump? Was it excitement about the show's 100th anniversary? Are audiences returning for the closing weeks? Whichever way you look at it, nearly 1.4 million more people watched FOX's "So You Think You Can Dance" this week than tuned in last week, reversing a slow regress for the show.

Aided by "So You Think You Can Dance," FOX won the 18-49 demographic with a 2.2 rating, topping the 1.9 rating for CBS. NBC was third in the key demographic with a 1.1 rating, with ABC's 0.8 rating and the 0.5 rating for The CW trailing.
