ABC and the USC Trojans were the big winners at the Orange Bowl on Tuesday night, but NBC also impressed with the perf of its eclectic lineup, which included a nice tune-in for new comedy “Committed.”

Sandwiched between unscripted weight-loss skein “The Biggest Loser,” which hit series highs, and a special “Dateline” at 10 featuring Matt Lauer’s interview with Amber Frey, “Committed” was the No. 2 nonsports choice in its 9:30 timeslot.

The romantic laffer from NBC Universal Television averaged a 4.5 rating/10 share in adults 18-49 and 10.11 million viewers overall, the net’s best showing with entertainment programming in the time period this season. Its 18-49 aud was roughly two-thirds female — not unexpected, especially opposite football.

“Committed” benefited from a sturdy lead-in from “The Biggest Loser,” which set highs (4.8/12 in 18-49, 11.34m) one week from its season finale and matched NBC’s best delivery in the time period (8-9:30 p.m.) in nearly two years. “Loser” was the top-rated nonsports choice in 18-49 with each of its half-hours.

NBC has programmed an additional firstrun seg of “Committed” for tonight at 8:30 after “Joey.” Beginning Jan. 18, it will follow “Scrubs” on Tuesdays.

Peacock closed out the first Tuesday of the new year with Lauer’s sit-down with former Scott Peterson girlfriend Frey on a special “Dateline” (6.0/15 in 18-49, 15.97m), airing in place of “Law & Order: SVU.” Newsmag grabbed its best demos of the season and its largest overall aud (for any night) in nearly three years.

For ABC, college football’s championship matchup between USC and the Oklahoma Sooners in the Orange Bowl (8:16 p.m.-12:09 a.m. ET) averaged a 7.4/19 in 18-49 and 21.42 million viewers overall — the best numbers for an ABC Tuesday in nearly five years, but below last year’s title tilt (the more competitive Oklahoma-Louisiana State in the Sugar Bowl).

Game turned into a blowout in the second quarter and wasn’t much of a contest after that. As a result, the primetime portion (7.9/20 in 18-49, 23.18m) rated higher than the game in its entirety.
