Chaotic Rating

Among adults 18-49: Britney Spears is a huge draw in the tabloids, and apparently just as much of one on television. UPN premiered the limited-run series “Britney & Kevin: Chaotic” last night and it nearly doubled the network’s 9 p.m. Tuesday timeslot, with 3.46 million total viewers, according to Nielsen overnights. “Veronica Mars” averaged just 1.87 million there this season.

“Chaotic,” which featured home movies of the now-married couple during their courtship, earned a 1.8 rating among viewers 18-49. But as usual, Fox’s “American Idol” was Tuesday night’s highest rated show in the demo, with a 10.1 average at 8 p.m. That led Fox to first place for the night with an 8.6 average rating and a 23 share. CBS finished second at 3.7/10, NBC third at 3.4/9, ABC fourth at 2.4/6, the WB fifth at 2.1/5 and UPN sixth at 1.5/4.

Fox led easily at 8 p.m. with its 10.1 average for “Idol.” CBS was second with a 2.7 for the first hour of its coverage of the Academy of Country Music Awards, with the WB third with a 2.3 for “Gilmore Girls.”

At 9 p.m. Fox led with a 7.0 average rating for “House.” CBS was second with a 4.1 for the second hour of the ACM Awards and ABC third with a 3.2 average for the last 20 minutes of supersized “George Lopez” and a 40-minute “According to Jim.”

At 10 p.m. NBC led with a 5.5 average for “Law & Order: SVU.” CBS was second with a 4.3 for the last hour of the ACM Awards and ABC third with a 2.2 for “Blind Justice.”

Fox finished first for the night among households with a 12.7 average rating and a 20 share. CBS finished second at 7.7/12, NBC third at 7.1/11, ABC fourth at 4.5/7, the WB fifth at 3.2/5 and UPN sixth at 2.2/3.
