bb13 july 21 ratings TV ratings: 'Big Brother' bounces back, helps CBS lead ThursdayFast National ratings for Thursday, Sept. 21, 2011

After dipping some a week ago, “Big Brother 13” saw its ratings improve some on Thursday, leading CBS to a win on a fairly quiet night. “So You Think You Can Dance” dipped a little bit, and ABC’s lineup of originals was flat or down a little bit in adults 18-49.

CBS led the way in primetime with 6.25 million viewers and a 4.0 rating/7 share in households. ABC (5.5 million, 3.3/6) finished second, a good distance ahead of FOX (3.95 million, 2.5/4). NBC was also down a little bit with 2 million viewers and a 1.4/2. The CW brought up the rear with 856,000 viewers and a 0.6/1.

CBS averaged only a 1.7 in the 18-49 demographic, but that was good enough to snag the top spot. ABC took second at 1.5, followed by FOX at 1.2. Neither NBC (0.7) nor The CW (0.3) managed to break the 1.0 barrier.
