Ratings: Chicago Code, Castle Up; Chuck Down

Fox’s The Chicago Code and ABC’s Castle were the only two shows to enjoy meaningful gains this Monday.

Leading out of the just-renewed House — which with 7.76 million viewers and a 2.9 rating was down in audience and matched last week’s season-low demo — Chicago Code copped 5.7 million viewers and a 1.7 rating, up 4 and 6 percent, respectively. Castle meanwhile dominated the 10 o’clock hour with an audience of 12.6 million and a 3.1 demo rating, up 4 and 7 percent.

Elsewhere this Monday:

8/7c | Dancing With the Stars topped the night with 20.2 million viewers and a 4.1 rating, down slightly week-to-week. How I Met Your Mother (6.4 mil/2.5) tied its series-low demo, while lead-out Mad Love (5.15 mil/1.8) plunged 18 percent to a new nadir. (Can I say “nadir” here?) Bubble boy Chuck (4.06 mil/1.3) slipped 7 percent to tie its all-time low demo. The CW’s 90210 (1.46 mil/0.7) held steady.

9/8c | With the Two and a Half Men repeats now pulling just 6.4 million viewers and a 1.7, Mike & Molly (7.5 mil/2.2) dipped to a new series low demo rating. The Event (3.77 mil/1.1) plunged 15 percent to match its all-time low. Gossip Girl (1.18 mil/0.6) tumbled 14 percent to a very scary demo.

10/9c | Hawaii Five-0 (9.2 mil/2.3) placed a distant second behind Castle, dipping a few points to a series-low demo rating. Law & Order: Los Angeles (5 mil/1.2) collared a few more viewers but dropped 14 percent in the demo.
