CBS’ Monday lineup posted across-the-board gains for a second straight week. How I Met Your Mother (4.5/12 in adults 18-49, 10.4 million total viewers) was up a tenth in 18-49 from last Monday, 2 Broke Girls (4.8/12, 11.7 million) was up 7% from its fast national last week to post its best 18-49 rating in the 8:30 PM slot, Two And A Half Men (5.3/12, 14.6 million) was up 4% to once again rank as the top program of the night in 18-49, and Mike & Molly (4.4/10, 12.2 million) was up 5%. Hawaii Five-0 (3.3/8, 11.5 million) flourished without scripted broadcast competition in the 10 PM hour, up 10% in the demo from its fast national last week to post its best demo and total viewer number since the season premiere. Hawaii will likely tie its season-high opener in the finals if it’s adjusted up a tenth as it normally is. CBS (4.2/10, 12 million) easily won the night in 18-49.

NBC’s Rock Center With Brian Williams (1.3/3, 4.5 million) last night boasted the biggest news “get” of the moment, an exclusive interview with former Penn State football coach and accused child molester Jerry Sandusky. The one-on-one with Bob Costas boosted the struggling newsmagazine to its highest rating to date, up 30% from the 1.0 Rock Center posted in its first two weeks. Still, the show was dwarfed in the 10 PM hour by another newsmagazine, ABC’s special edition of 20/20 (2.8/7, 13.4 million) featuring Diane Sawyer’s interview with recovering shooting victim U.S. Rep. Gabrielle Giffords, as well as CBS’ Hawaii Five-0. Rock Center also ranked as the lowest-rated program on the Big 4 networks, and its fast national numbers may have been inflated by a local NFL pre-emption in Minneapolis, so an adjustment down is likely. Ditto for NBC’s The Sing-Off (1.5/4, 4.7 million). UPDATE 1:30 PM: Both The Sing-Off and Rock Center were adjusted down to a 1.3 and a 1.1, respectively, leaving the newsmagazine with a week-to-week bump of only a tenth of a rating. ABC’s Dancing With The Stars (3.4/8, 18.5 million) was up a tenth in the demo from last week’s fast national, while 20/20 posted ABC’s best ratings for a newsmagazine since Sawyer’s interview with another survivor, Jaycee Dugard, in July. ABC (3.2/8, 16.8 million) won the night in total viewers. (The network had local NFL pre-emtions in about 1% of the country.)

Both of Fox’s dramas posted declines. Terra Nova (2.3/6) was down 12%, while House (2.5/6) was down 7% from its fast national. The declines were disproportionally bigger on the male side, which is a bit puzzling because Monday Night Football on ESPN (9.2 metered market average) was also down, by 21%, from last week. The CW’s Monday dramas held steady.
