Rules Of Engagement TV RatingsCBS’ regular Thursday lineup returned last night after two weeks of NCAA basketball, bringing with it veteran Rules Of Engagement. The Big Bang Theory (4.5/15 in adults 18-49, 13.6 million total viewers) was down 13% from its last original three weeks ago but still ranked as the top program of the night in 18-49. Rules Of Engagement (2.8/8) was up a tenth from its last original in December and down two tenths from the last Rob that aired behind a new Big Bang. Person Of Interest (3.3/9) and The Mentalist (2.7/8) were both down a tenth from their last originals three weeks ago.

Fox’s American Idol (4.2/13, 15.3 million viewers) was up 5% in 18-49 and 2% in total viewers from last week’s fast nationals. Touch (2.8/7) was down 13% from its official series premiere last week. Fox won the night in 18-49, CBS in total viewers.

Community TV RatingsNBC’s Community (1.7/6) matched its demo result from last week when it didn’t face Big Bang and ranked as NBC’s highest-rated program on Thursday night for a second straight week with The Office in repeats. 30 Rock (1.5/4) also was flat with last week, while Up All Night (1.3/4) was down 13% and Awake (1.0/3) was down 17%, both hitting series lows. With such dismal performance, NBC (1.3/4 in 18-49) fell behind Univision (1.5/4) on a night the peacock once dominated.

Like Awake and Touch, the third midseason Thursday drama, ABC’s Missing (1.4/4, 7.7 million), also fell, down 12% from last week to a new low. Grey’s Anatomy and Private Practice were reruns. The CW’s The Vampire Diaries (1.1/3) and The Secret Circle (0.6/2) were both down to season/series lows.
