On a night when the competition mostly aired repeats, ABC’s lineup of originals — led as usual by ”Modern Family” , dominated the ratings race. CBS did pretty good with its latest ”I Get That a Lot” special, but auds didn’t show up for Fox’s ”Mobbed.”

According to preliminary national estimates from Nielsen, ABC saw all of its programs grow from their season lows in December, starting with ”The Middle” (3.0 rating/9 share in adults 18-49, 10.0 million viewers overall) and ”Suburgatory” (2.9/8 in 18-49, 8.7 million viewers overall), which led the night’s opening hour in all key categories. The net then surged at 9 p.m. with ”Modern Family” (5.6/14 in 18-49, 14.0 million viewers overall) and then stayed comfortably on top at 9:30 p.m. with ”Happy Endings” (3.3/8 in 18-49, 7.7 million viewers overall). Capping the night, ”Revenge” (2.5/7 in 18-49, 8.0 million viewers overall) easily beat the demo scores for repeat dramas on CBS and NBC.

For the night, ABC won in all key demos as well as total viewers, rising more than 20% in all categories vs. the comparable night a year ago when it also aired all originals.

CBS finished second, getting good mileage out of its ”I Get That a Lot” special (2.3/6 in 18-49, 8.3 million viewers overall) and repeats of dramas ”Criminal Minds” (2.0/5 in 18-49, 8.2 million viewers overall) and ”CSI” (1.7/5 in 18-49, 8.1 million viewers overall).

Fox followed a repeat of ”Glee” (0.8/2 in 18-49, 2.4 million viewers overall) with the premiere of limited-run series ”Mobbed” (1.2/3 in 18-49, 3.0 million viewers overall); though soft, it did grow in its second half-hour.

And NBC had a quiet night with encores of ”Up All Night” (1.0/3 in 18-49, 3.5 million viewers overall), ”Whitney” (1.0/3 in 18-49, 3.1 million viewers overall), ”Harry’s Law” (0.8/2 in 18-49, 4.6 million viewers overall) and ”Law and Order: SVU” (1.1/3 in 18-49, 3.7 million viewers overall). The net’s new comedy pairing of ”Whitney” and ”Are You There Chelsea” bows next week.

CW aired a pair of ”The Secret Circle” repeats, averaging a 0.3/1 in 18-49 and about 900,000 viewers overall. ”One Tree Hill” returns for its final season on Wednesdays beginning next week.

Preliminary 18-49 averages for the night: ABC, 3.3/9; CBS, 2.0/5; Univision, 1.5/4; Fox, 1.0/3; NBC, 1.0/2; CW, 0.3/1.
