FOX averaged 16.4 million viewers and a 9.4 rating/15 share in households Thursday night, leading second-place CBS (12.1 million, 7.6/12) by a comfortable margin. ABC came in third overall with 8.8 million viewers and a 5.6/9. NBC (2.4 million, 1.5/2) was well off the pace with a lineup of mostly repeats. The CW trailed with 1.2 million viewers and a 0.8/1.
