ABC‘s Last Man Standing (1.4 in adults 18-49) lived up to its name last night as the only scripted or unscripted program to post week-to-week gains, 17%. But it was the other ABC bookend program, newsmagazine 20/20 at 10 PM, that posted the biggest overall week-to-week increase, and that may be saying something about our society. An hour devoted to “people engaging in behavior that is thoughtless, questionable, or wrong” shot up 33% in adults 18-49 (1.6) and 33% in total viewers (5.9 million) to log 20/20‘s biggest audience and highest Adult ratings since March and May, respectively. What’s more, that edition of 20/20 topped everything else on TV last night besides ABC’s Shark Tank (1.8, down a tenth from its fast national last week). With The Neighbors (1.0) flat week to week, ABC edged CBS to reclaim the Friday 18-49 crown (1.5 vs. 1.4).

CBS, which was the demo winner on Premiere Friday, was hurt by a 18-49 decline for anchor Blue Bloods (1.4), which was down 17% airing against 20/20 but the biggest audience draw with a massive for Friday standards 11.1 million viewers. Undercover Boss (1.4) was down a tenth, while Hawaii Five-0 (1.5) matched its fast national from last week. In total viewers, which is the main currency on the older-skewing Friday night, CBS had no competition with 9.4 million viewers, dwarfing everyone else (ABC, 5.8 million; NBC, 4.9 million; Fox, 3.1 million)

After its promising debut last week, Fox’s Masterchef Jr. (1.3) was down 19% in Week 2. NBC’s Dateline (1.2) was down a tenth, followed by an Elizabeth Smart news special (1.2). The CW’s America’s Next Top Model (0.4) was flat.
