ashton kutcher men 320 TV ratings: 'Terra Nova,' 'Two and a Half Men' fall Monday, 'Dancing' upFast national ratings for Monday, Oct. 17, 2011

“Dancing With the Stars” improved some on its ratings from last week and helped lead ABC to a win in total viewers Monday night. CBS stayed on top among adults 18-49, although “Two and a Half Men” dropped again to numbers right in line with last season’s performance.

FOX’s “Terra Nova” and “House” were also off a little from their performances two weeks ago (although up from last week’s baseball-delayed start times), and “The Sing-Off” improved slightly for NBC.

ABC drew 15.5 million viewers and a 10.1 rating/15 share in households for the night, beating CBS (11.5 million, 7.0/11) by 4 million viewers. FOX (8.2 million, 4.9/7) came in third. NBC averaged 3.8 million viewers and a 2.3/4 to finish fourth. The CW (1.5 million, 1.1/2) was up a little bit from last week, although that may change as the net’s Miami affiliate aired “Monday Night Football.”

CBS led the adults 18-49 demographic with a 4.0 rating. ABC grabbed second with a 3.0, edging FOX’s 2.9. NBC’s 1.3 was good enough for fourth, while The CW drew a 0.7.
