TV Ratings: Adele, Miss USA Lead NBC; 'Secret Millionaire,' 'Extreme Makeover' Return Softly

The Grammy winner's concert special and the annual pageant post the strongest numbers on a relatively sleepy Sunday.

NBC enjoyed the spoils of a soft summer Sunday, winning the night among adults 18-49 and placing second in viewers to CBS' block of encores.

A boosted Dateline kicked off the night for the Peacock with a 0.9 adults rating, leading into concert special Adele: Live in London (1.7 in the demo) and the night's strongest performer, the 2012 Miss USA Pageant. The two-hour special pulled a 1.8 adults rating, giving NBC a 1.5 demo score for the night and 5.8 million viewers.
