With much of the prime-time broadcast competition airing repeat programming Thursday night, CBS dominated the ratings, based on Nielsen overnights.

TVbytheNumbers.com reports that CBS averaged a 3.7 rating for prime time in the key 18-49 demo, well ahead of second-place Univision (1.7 average) and even further ahead of the English-language networks. Fox settled for a 1.1, followed by NBC (0.8) and ABC (0.8).

CBS was also dominant in total viewers, averaging 14.9 million for the evening to 4.2 million for Univision, 3.3 million for ABC, 2.9 million for Fox and 2.5 million for NBC.

CBS’s “The Big Bang Theory” was the top-rated show of the night, equaling its series high with a 6.0 average rating in viewers 18-49. “Two and a Half Men” rose to a season-high 4.6 and “Person of Interest” matched its series high with a 3.4. “Elementary” delivered a 2.5, up 9% from its previous fresh episode, which aired Dec. 13.

With NBC and ABC airing all repeats, the toughest English-language competition came from Fox, and it didn’t pose much of a threat. Back-to-back episodes of “Mobbed” managed only a 1.0 average and a 1.2 in the 18-49 demo.
