"American Idol" rose in the ratings Wednesday according to early numbers from Nielsen, orchestrating a weeknight win for Fox. 

The veteran singing contest, Fox's only program for the night, earned a 2.1 average rating among key 18-to-49-year-old viewers, up 11% from a week ago. 

The second-place network among young adults, ABC, was the one with the highest-rated show in the key demo: "Modern Family." The sitcom scored a 3.4 in 18-to-49, up slightly from its most recent episode, while "The Middle" and "Suburgatory" each fell a bit. The new comedy "Mixology" rose 25% to a 1.5. 

CBS' "Survivor" was the night's most-watched show, with 9.3 million viewers overall and a 2.2 in 18-to-49, down 4%. 

NBC showed only reruns.
