Sunday's ratings scorecard:
ABC's coverage of the 2008 American Music Awards topped the hour, dominated Sunday's demos and averaged 12.2 million total viewers for the night (a gain of 380 versus last year). Coming in No. 2 at 8 was 24: Redemption, which delivered 12.04 million heads over its two-hour run. That marks an 18-percent improvement over the Fox series' Day 6 finale, but down 23 percent from that season's opener.
NBC's coverage of the Colts-Chargers game was the evening's most-watched program, averaging 12.29 million viewers. Facing stiff competition, Amazing Race (10.1 mil) slowed down 19 percent week-to-week.
Cold Case placed third behind the AMAs and football with 12.07 million viewers, on par with its previous audience.
The Unit inched up 200K to claim No. 3 with an audience of 9.99 million.
