'Big Brother' delivers its best ratings of season

A strong showing by one of professional golf’s biggest tournaments helped guide CBS to a ratings victory on Sunday night, with the net’s “Big Brother” delivering its largest overall audience of the season.

According to Nielsen, final-round coverage of the 2007 PGA Championship from Tulsa, Oklahoma averaged a 6.8 household rating/15 share in the metered-market overnights, making it the fifth highest-rated conclusion to the tournament since 1986.

It certainly helped CBS that Tiger Woods was in the hunt and went on to notch his 13th career major victory. This year’s score trails only 2000′s 10.0/23 in the overnights (Tiger’s second PGA Championship victory); 2002’2 8.0/17 (Tiger’s loss to Rich Beem by one stroke); 1999′s 7.7/18 (Tiger’s first PGA Championship title); and last year’s 7.2/16 (Tiger’s third PGA Championship victory).

The golf action extended about 11 minutes into primetime in much of the country, with the overrun lifting CBS to victory on the night among young adults as well as total viewers. “60 Minutes” averaged roughly a 2.1/7 in adults 18-49 and 10 million viewers overall, airing from 7:11 to 8:11 p.m. in much of the country. It was followed by “Big Brother 8″ (roughly 2.8/9 in 18-49, 8.2 million viewers overall from 8:11 to 9:11 p.m.), which tied its best Sunday score to date among adults 18-49 while delivering its largest overall audience.

Elsewhere in primetime, Fox racked up its usually solid numbers for repeats of the animated comedies “Family Guy” (3.1/9 in 18-49, 6.5 million viewers overall at 9:30 and 2.8/8 in 18-49 and 5.7 million viewers overall at 9 p.m.), “The Simpsons (2.3/7 in 18-49, 4.8 million viewers overall) and “American Dad” (2.2/7 in 18-49, 4.6 million viewers overall).

ABC was paced by repeats of “Extreme Makeover: Home Edition” (2.2/7 in 18-49, 6.7 million viewers overall) and “America’s Funniest Home Videos” (1.9/7 in 18-49, 6.2 million viewers overall), and NBC should average about a 2.0/6 in adults 18-49 and 6 million viewers overall for its NFL preseason game between the San Diego Chargers and Seattle Seahawks.
