With football taking a break and NBC saddled with low-rated figure skating, ABC cruised to victory Sunday among young adults behind “America’s Funniest Home Videos” and a two-hour “Extreme Makeover: Home Edition.” CBS, meanwhile, won the night rather easily in total viewers.

According to preliminary nationals from Nielsen, ABC opened the night with a narrow demo victory courtesy of “America’s Funniest Home Videos” (2.8 rating/8 share in adults 18-49, 8.3 million viewers overall), and then opened up a wider advantage from 8 to 10 p.m. with “Extreme Makeover: Home Edition” (5.1/12 in 18-49, 13.6 million viewers overall), which won each half-hour among adults 18-49. Net then fell to third with a repeat of “Brothers & Sisters” (1.8/5 in 18-49, 4.6 million viewers overall), but by then it had done enough to win the night in 18-49.

At CBS, “60 Minutes” (2.7/7 in 18-49, 14.4 million viewers overall) won the opening hour among adults 25-54 and total viewers, followed by an original episode of “Shark” airing at a special 8 o’clock time (2.0/5 in 18-49, 11.1 million viewers overall). From 9 to 11 p.m, the Hallmark Hall of Fame presentation of “The Russell Girl” averaged a 2.2/5 in 18-49 and 12.7 million viewers overall, winning its time period in overall audience.

NBC barely registered from 7 to 9 p.m. with the “U.S. Figure Skating Championships” (0.8/2 in 18-49, 4.8 million viewers overall) but became more competitive the rest of the night with its “Guinness World Records: Top 100” special (2.2/5 in 18-49, 6.3 million viewers overall). “Guinness” won the 10 o’clock hour in adults 18-49 and all key male demos.

Fox had a ho-hum night, starting with a special off-night repeat of “Are You Smarter Than a 5th Grader” (1.4/4 in 18-49, 4.3 million viewers overall). Things got better with original episodes of “The Simpsons” (3.6/9 in 18-49, 7.6 million viewers overall) and “King of the Hill” (3.7/9 in 18-49, 7.5 million viewers overall) as well as a repeat of 9 o’clock laffer “Family Guy” (3.8/9 in 18-49, 7.6 million viewers overall).
