TV ratings: 'Big Brother' doubles down to lead Thursday

bb-fight.JPGFast National ratings for Thursday, Aug. 26, 2010

A double elimination on "Big Brother 12" lifted CBS to a ratings victory Thursday night.

CBS delivered 7.3 million viewers and a 4.5 rating/8 share in households for the night, finishing a healthy distance ahead of second-place ABC (5.6 million, 3.5/6). FOX's 3.5 million viewers and 2.3/4 was good enough for third. NBC (2.9 million, 2.0/4) came in fourth, and The CW trailed with 1.5 million viewers and a 0.9/1.

(Note: A handful of local affiliates aired NFL preseason games in primetime, which may skew the ratings a little.)

CBS also led among adults 18-49, although it managed only a 1.9 in the demographic. ABC took second with a 1.6, followed by FOX at 1.1. Neither NBC (0.9) nor The CW (0.5) could break above 1.0.
