NBC is singing a happy tune as "The Voice" and "The Sing Off" helped the net dominate Monday's ratings race, delivering roughly the same number of young adults as the next two closest broadcasters combined.

ESPN figures to again win the night with its "Monday Night Football" matchup between the Baltimore Ravens and Detroit Lions, which did a 9.7 overnight household rating. This should translate to something in the vicinity of 14 million viewers, and nearly a 5 demo rating.

Ratings for the Peacock programs could be adjusted a bit in the nationals, as the net's preliminary averages include Ravens football action in Baltimore. But in the early results, the live final performances of "The Voice" averaged a 3.3 rating/8 share in adults 18-49 and 12.7 million viewers overall from 8 to 10 p.m., nearly in line with last week's one-hour average and Monday's No. 1 entertainment program in 18-49.

It's likely, though, that last night's "Voice" will be the show's lowest-rated performance finale to date. The music contest wraps its fifth season tonight.

At 10 p.m., "The Sing-Off" (2.2/6 in 18-49, 7.8 million viewers overall) won its timeslot among the broadcasters in all key categories, retaining about 90% of last week's two-hour season-premiere 18-49 score (2.4).

Elsewhere, CBS ran a solid second with its lineup of "How I Met Your Mother" (2.7/8 in 18-49, 7.7 million viewers overall), "2 Broke Girls" (2.3/7 in 18-49, 7.6 million viewers overall), "Mike & Molly" (2.2/6 in 18-49, 8.8 million viewers overall), "Mom" (1.9/5 in 18-49, 7.3 million viewers overall) and "Hostages" (1.2/3 in 18-49, 5.1 million viewers overall).

The comedies all ran second among the Big Four to "The Voice" in 18-49, with "Mike & Molly" up week-to-week in 18-49 and drawing the show's largest overall audience since its Nov. 4 season premiere. And at 10 p.m., "Hostages" took advantage of no competing broadcast dramas in the hour to post its best scores since October.

At Fox, "Almost Human" continues to do OK (1.6/5 in 18-49, 5.3 million viewers overall), but down 11% (0.2) from last week, when it had "Sleepy Hollow" behind it. Last night, "Human" was followed by special repeats of "Ice Age: A Mammoth Christmas" (0.9/2 in 18-49, 2.7 million viewers overall) and "Dragons: Gift of the Night of Fury" (0.8/2 in 18-49, 2.4 million viewers overall).

ABC went with special repeats of "Prep & Landing" (1.0/3 in 18-49, 4.1 million viewers overall) and "Prep & Landing: Naughty vs. Nice" (1.0/3 in 18-49, 3.9 million viewers overall), followed by limited-run series "The Great Christmas Light Fight" (1.2/3 in 18-49, 4.6 million viewers overall), which was down 14% (0.2) from last week. The Alphabet's numbers also figure to be adjusted in the nationals, as its early numbers include Lions football action in Detroit.

CW aired encores of specials "Grandma Got Run Over By a Reindeer" (0.4/1 in 18-49, 1.2 million viewers overall) and "Victoria's Secret Fashion Show" (0.4/1 in 18-49, 1.0 million viewers overall), the latter of which had aired one week earlier on CBS.

Preliminary 18-49 averages for the night: NBC, 3.0/8; CBS 1.9/5; Fox, 1.2/3; ABC and Univision, 1.1/3; Telemundo, 0.6/2.

In total viewers: NBC, 11.1 million; CBS, 6.9 million; ABC, 4.4 million; Fox, 3.9 million; Univision, 2.8 million; Telemundo, 1.3 million; CW, 1.1 million.
