ABC had a couple things to party about Wednesday night.

"Super Fun Night," the freshman comedy starring Rebel Wilson, got a super big surge in the 18-to-49 age group compared with its last first-run airing two weeks ago, growing its rating 24% to a 2.1, according to early numbers from Nielsen.

Also, "Modern Family" was the highest-rated show in the key 18-to-49 demographic, though it slipped a bit from its last original episode three weeks ago to a rating of 3.8. It gained slightly in total viewership to an average of 10.6 million. Elsewhere on ABC, "The Middle," "Back in the Game" and a much talked-about episode of "Nashville" saw single-digit gains.

Overall, ABC was second in the advertiser-desired demo, with a 2.2, in which a rating point equals about 1.3 million young-adult viewers. Its average total viewership came in at 7.11 million. 

CBS won the night (2.4 rating; 10.5 million viewers) with help from "Criminal Minds" (Wednesday's most-watched show), which grew 17% from last week to a 2.7 in 18-49 and drew 11.6 million viewers. "Survivor" fell a tad to a 2.4 and "CSI" rose to a 1.9. 

Fox recovered from a rough previous week, gaining 13% to a 1.7 in the demo and rising 29% to 5.8 total viewers on average. Last week's episode was marred by a voting error that forced a Thursday do-over. 

On NBC, "Law & Order: SVU" hit its highest rating in nearly a month, increasing 7% to a 1.6 in the demo. "Revolution" is still pulling a 1.4 -- for the fifth week in a row, in fact. A 10 p.m. "Dateline NBC" drew a 1.1 and 5 million viewers. 

The CW looked solid with comic book series "Arrow," which rose 10% in 18-49 to a 1.1, matching its season high, and "Tomorrow People," which held steady with last week's 0.6.
