Ratings: As ACM Awards Top Sunday, Once Upon a Time and GCB Dip to New Lows

CBS’ coverage of the Academy of Country Music Awards dominated Sunday’s broadcast TV ratings, averaging 13 million total viewers and a 3.1 rating (down just 6 percent in the demo versus last year).

Among the award show’s causalities, ABC’s Once Upon a Time (8.2 mil/2.7) and GCB (5.84 mil/1.9) dropped 7 and 10 percent in the demo, respectively, with each hitting new all-time lows. Desperate Housewives, however, was steady at 8.4 mil/2.6.

Elsewhere, NBC’s three-hour (!) Celebrity Apprentice-thon averaged 5.9 mil and a 1.8, on par with its most recent tallies…. Bob’s Burgers (3.6 mil/1.6), leading out of a Simpsons rerun, dropped 20 percent in the demo, while Family Guy (5.1 mil/2.5) fell 11 percent and American Dad (4.22 mil/2.0) was flat.
