Despite little promotion, The X Factor snagged a surprise berth on Sunday and ended up clobbering the entertainment competition, which routinely takes a hit from football on NBC.

Naturally, the Peacock dominated on Sunday because of the gridiron action; the Vikings versus the Bears earned a 5.7 rating/13 share among adults 18-49, according to early results. But The X Factor was the night’s most popular entertainment program in the demo, earning a 3.3/8 and 8.6 million viewers. That’s down 11% from Thursday’s competition but hey, you didn’t know it was on. It wasn’t confirmed to air until after Saturday’s ALCS playoffs game was over.

Each 18-49 ratings point equals 1.3 million viewers.

The ABC shows continue to lose favor with viewers: Though America’s Funniest Home Videos was up 7% to a 1.5/4 and 6.4 million, Extreme Makeover: Home Edition was down 5% to a 1.9/5 and 7.1 million, Desperate Housewives was down 4% — and tied its series low — with a 2.7/6 and 8.2 million, and Pan Am posted its lowest-rated telecast to date with a 1.8/4 and 5.8 million. Death watch, anyone? Any new show that starts to earn below a 2 rating may end up swimming with the fishes. Stay tuned there.

On CBS 60 Minutes earned a 1.9/5 and 10.9 million, followed by The Amazing Race (2.5/6, 9.2 million) and The Good Wife (2.1/5, 10 million). Good news for David Caruso, though: CSI: Miami was up 9% to a 2.4/6 and 10.5 million.

Bottom line: NBC won the night in the demo with a 4.8/12, followed by Fox (4.4/11), CBS (2.2/5) and ABC (2.0/5). In viewers, NBC was first with 12.3 million, followed by Fox (11.6 million), CBS (10.6 million), and ABC (6.9 million).
