"Dancing with the Stars" fell off some from its premiere but still had a big night Monday, while "Castle" followed last week's series high with an even bigger audience this time around.

ABC dominated primetime with 19.9 million viewers and a 12.5 rating/20 share in households. A night of (mostly) repeats on CBS (8.3 million, 5.2/8) came in second. FOX (6.9 million, 4.3/7) came in third, ahead of NBC's 5.45 million viewers and 3.4/6. The CW (1.85 million, 1.2/2) brought up the rear.

The story was the same in the adults 18-49 demographic, where ABC's 4.9 rating was the night's best by a wide margin. CBS' 2.8 was good for second. FOX finished third at 2.2, followed by NBC, 1.8, and The CW, 0.9.
