Here is one problem with the current broadcast comedy series — there are too many “hammock” shows that do respectable business with a strong lead-in but not enough tentpole comedies to hold those comedy tents that are popping up all over the schedule. CBS has that problem with its Monday lineup. 2 Broke Girls, which was red hot airing in the hammock 8:30 PM slot in its first season, was promoted to the 9 PM anchor slot last fall. It gradually lost steam. Its decline was accelerated this fall to a point where CBS decided to put the show back at 8:30 PM for much needed rehab. The move has worked well for 2 Broke Girls, which immediately rebounded. Last night, it inched up another tenth to a 2.7 in adults 18-49, only a tenth from its season high posted by the September opener. That despite its lead-in, How I Met Your Mother (3.1), being down 9% week to week. It still was CBS’ highest rated program of the night. Therein lies the problem. Another comedy, which has done perfectly fine as a “hammock” show at 9:30 PM, Mike & Molly, was assigned the 9 PM slot. In its season premiere last week, Mike & Molly logged its lowest-rated opener but still held onto its 2 Broke Girls lead-in. Last night, the comedy starring Melissa McCarthy (2.2) fell 15% from last Monday’s debut and 19% from its lead-in. The ratings slide continued with Mom (1.9, down 5% to tie its lowest fast national to date) and Hostages (1.1, flat and tied for series low).

For NBC, ABC and Fox, it was across the board gains, losses or status quo, respectively. NBC’s The Voice (3.8) and The Blacklist (3.0) rebounded from last week. The Top 12 performance show was up 6%, while The Blacklist was up a tenth. While Blacklist‘s Live+Same Day 18-49 ratings have fluctuated in the 2.9-3.1 range in the past five weeks, in Live+3, the show has been steadily growing for the past four weeks and last week again broke its record for the largest viewership L+3 lift with 5.427 million. NBC won Monday in 18-49 (3.5), topping every half-hour of primetime.

ABC’s Dancing With The Stars (1.7) was down 15% to an all-rime Monday low, while Castle (1.9) was down 14%. ABC still was able to squeak past NBC to top the night in total viewers (11.7 vs. 11.5 million), with Dancing ranking as the most watched program of the night for a third consecutive week. (12.5 million vs. 11.9 million for The Voice.)

In its time slot finale before moving to Fridays to make room for Almost Human, Fox’s Bones (2.0) was flat with last week, as was Sleepy Hollow (2.5). The CW’s Hart Of Dixie (0.4) and Beauty & The Beast held steady but their numbers may have been inflated by an NFL preemption in Miami.
