NBC’s “Sunday Night Football” kept its undefeated streak on the night intact despite a lopsided contest, while Fox’s animated comedies returned and ABC’s “Desperate Housewives” ruled as the evening’s top entertainment series.

According to preliminary nationals from Nielsen, the Green Bay Packers’ 45-7 demolition of the Dallas Cowboys averaged a 6.7 rating/17 share in adults 18-49 and 17.2 million viewers overall on NBC’s stations from 8:30 to 11 p.m., with the game’s averages expected to rise some in the nationals that are released Tuesday. “SNF” has been the No. 1 program all nine Sundays of the football season.

Green Bay opened up a 28-7 halftime lead, which led to decreased ratings in the second half. As a result, the game’s overnight metered-market score of a 12.4 household rating/19 share came in below last year’s Week 9 Dallas-Philadelphia contest, which earned a 14.3/23 for a competitive result. Top local scores Sunday came from Milwaukee (45.8% of households were watching) and Dallas (27.8%).

Elsewhere, CBS benefited in a big way from football as well, as the conclusion of its late-afternoon games extended roughly 65 minutes into primetime. Numbers for the net’s series on the night are subject to significant revision in the nationals, with “60 Minutes” (4.0/10 in 18-49, 15.6 million viewers overall) expected to drop some in the demo, while “Amazing Race” (3.2/7 in 18-49, 11.3 million viewers overall) and “Undercover Boss” (2.6/7 in 18-49, 9.9 million viewers overall) should grow.

ABC’s “America’s Funniest Home Videos” (1.6/4 in 18-49, 7.6 million viewers overall) was lower than would be expected due to the football overrun, but the net jumped up at 8 p.m. with “Extreme Makeover: Home Edition” (2.5/6 in 18-49, 9.3 million viewers overall), which likely benefited from facing “60 Minutes” and not competing reality program “Amazing Race” on CBS in most of the country. The unscripted series were followed by “Desperate Housewives” (4.0/10 in 18-49, 15.6 million viewers overall) and “Brothers and Sisters” (2.6/7 in 18-49, 9.9 million viewers overall), both of which were up vs. their scores of the previous week. “Housewives” figures to log the top non-sports series score of the night in 18-49.

At Fox, “The Simpsons” (3.7/9 in 18-49, 8.2 million viewers overall), “The Cleveland Show” (3.1/7 in 18-49, 6.7 million viewers overall), “Family Guy” (3.8/9 in 18-49, 8.0 million viewers overall) and “American Dad” (2.9/7 in 18-49, 6.3 million viewers overall) were all by double-digit percentages vs. their last original episodes on Oct. 10; the shows had been sidelined by baseball-related preemptions or repeats the previous three weeks.

Preliminary 18-49 averages for the night: NBC, 5.3/13; CBS, 4.6/12; Fox, 2.8/7; ABC, 2.7/7; Univision, 1.2/3.

In total viewers: CBS, 16.1 million; NBC, 14.0 million; ABC, 9.6 million; Fox, 6.2 million; Univision, 3.1 million.
