Fox claimed an easy win in the Wednesday prime-time ratings even though CBS's "Survivor" again topped Fox's "American Idol" in head-to-head competition, based on Nielsen overnights for the key 18-49 demo.

TVbytheNumbers.com reports that "Survivor" averaged a 2.2 rating in viewers 18-49 in the 8 p.m. hour, while Fox's two-hour "Idol" delivered a 2.1. But CBS went into repeat mode after "Survivor" with rebroadcasts of "Criminal Minds" (1.2 average) and "CSI" (1.2), and the Tiffany Network wound up third overall.

"Survivor's" 2.2 was a season low, and off one-tenth from a week ago. "Idol" was up two-tenths from last week.

ABC had the night's top-rated broadcast show in "Modern Family," which ticked up one-tenth from its previous original episode to a 3.4 average in 18-49 as ABC came in second overall. ABC's "The Middle" fell two-tenths to a 1.8, "Suburgatory" was off one-tenth with a 1.6 and "Mixology" surged three-tenths from last week to a 1.5.

ABC's 10 p.m. music special "Nashville: On the Record" settled for a 1.0 in the 18-49 demo.

NBC wound up in fifth place among the broadcast nets with an all-repeat lineup of two "Law & Order: SVU" episodes (1.0 and 1.1 in adults 18-49) and "Chicago PD" (0.9).

For prime time overall, Fox led the way in the 18-49 demo with a 2.1 average, followed by ABC (1.7 average), CBS (1.5), Univision (1.2) and NBC (1.0). Fox also won total viewers, averaging 8.9 million to lead CBS (7.6 million), ABC (5.6 million), NBC (4.1 million) and Univision (2.9 million).
