With a two-hour American Idol (7.4/21 in adults 18-49, 24.9 million viewers), Fox easily won last night in 18-49 and total viewers. Versus last Wednesday’s performance show, Idol was down 9% in the demo. (All week-to-week comparisons this week are probably affected by the switch to daylight saving time. TV use in the 8-10 slot last night was down 4% from last week.) Compared with the comparable telecast last year, Idol was down also 9% in 18-49.

The time shift also likely impacted the rest of the 8 PM shows last night. CBS’ Survivor: Redemption Island (3.1/10) was down a tenth from last week for a new series low; NBC’s Minute to Win It (0.9/3) was down 10%, also for a series low; and the CW’s America’s Next Top Model (0.8/3) was down 27%. (ABC aired comedy repeats in the 8 PM hour.)

CBS’ Criminal Minds (3.6/10) was flat with its most recent original two weeks ago, while its spinoff Criminal Minds: Suspect Behavior (2.6/7) shot up 18% with an original Minds as a lead-in versus a repeat last week. Following a Modern Family repeat, midseason ABC comedy Mr. Sunshine (1.8/5) was flat with last week and tied a series low. Ditto for midseason drama Off the Map (1.4/4) at 10 PM. NBC aired Law & Order: SVU repeats at 9 PM and 10 PM.
