ABC and Fox were the only games in town on a quiet Thanksgiving Eve. The two networks featured all-original lineups that posted double-digit declines and series/season lows across the board. (The shows’ season averages won’t suffer though as last night’s broadcasts were labeled as specials.) ABC’s Modern Family (4.5/13 in adults 18-49, 12.6 million viewers) was once again the top program Wednesday night in total viewers and 18-49. It was down 20% from last week to a season low. The Middle (2.5/8) was down 17% to a season low; Suburgatory (2.5/8) was down 14% to a series low; Happy Endings (2.7/7) was down 16% to a season low; and Revenge (2.1/6) was down 19% to a series low. ABC (2.7/8, 8.6 million) topped the night in 18-49 and total viewers, up 16% in viewers and 17% in 18-49 from the same night last year when the network also aired all-originals.

Fox’s X Factor results show (2.5/8) was down 19% from last week’s Thursday results show for a series low. A special telecast of the Howie Mandel-hosted series of specials Mobbed drew an underwhelming 1.6/4,  proving how 2010 the flash mob fad is. A new Up All Night (1.5/5) on NBC was down 21% to a series low. Following an Up All Night rerun, a Biggest Loser: Where Are They Now? special pulled in a 1.2/3. CBS aired a Survivor clip show (1.9/6) followed by drama repeats.
