ABC, CBS and Fox each had reason to be happy about Monday’s primetime ratings results, with the season finale of “House” helping Fox to finish in a tie with CBS for the night’s lead among young adults. ABC claimed the night’s most-watched program overall with “Dancing With the Stars.”

NBC, meanwhile, can put a fork in any further plans to resuscitate “Deal or No Deal” after the gameshow fizzled for a second straight week in its first primetime appearance in five months. The net rebounded some to finish the night with two hours of crime drama “Medium.”

According to preliminary nationals from Nielsen, “House” (4.6 rating/13 share in adults 18-49, 12.3 million viewers overall) rolled in key demos during the 8 o’clock hour and stood as the night’s top show in 18-49 as well as 18-34 (3.9/13). The net then fell to third place at 9 o’clock with “24” (3.3/8 in 18-49, 10.0 million viewers overall). Like “House,” “24” was flat week to week.

At CBS, the season finale of “The Big Bang Theory” got the night off to a strong start (3.6/11 in 18-49, 9.8 million viewers overall), beating ABC’s “Dancing With the Stars” among the 18-49 crowd and placing second in its timeslot in the demo. “How I Met Your Mother” (3.6/10 in 18-49, 8.7 million viewers overall) followed with solid scores, and “Two and a Half Men” was again the comedy block’s top draw despite a lower than usual score (4.4/11 in 18-49, 12.9 million viewers overall). “Rules of Engagement” (3.6/9 in 18-49, 10.1 million viewers overall) placed second at 9:30 p.m., and “CSI: Miami” led as usual during the 10 o’clock hour (3.9/11 in 18-49, 13.4 million viewers overall).

ABC’s “Dancing With the Stars” was at the low end of its range (projected 4.2/11 in 18-49, 18.8 million viewers overall from 8 to 10:02 p.m.), while drama “Castle” finished its rookie season in line with recent averages (projected 2.4/6 in 18-49, 9.9 million viewers overall from 10:02 to 11 p.m.).

“Deal or No Deal” dealt NBC a woeful sixth-place demo finish at 8 o’clock (1.0/3 in 18-49, 4.2 million viewers overall), delivering roughly one-quarter of the rating it was earning at the show’s peak a couple of years ago. Closing out the night were a pair of firstrun episodes of “Medium,” starting with a special hour at 9 (1.9/5 in 18-49, 6.3 million viewers overall) and the show’s regularly scheduled episode at 10 (2.3/6 in 18-49, 7.3 million viewers overall).

At CW, “Gossip Girl” (1.2/3 in 18-49, 2.3 million viewers overall) and “One Tree Hill” (1.1/3 in 18-49, 2.3 million viewers overall) were in line with their recent performances, both placing fifth in their time periods among adults 18-34.

Preliminary 18-49 averages for the night: Fox, 3.9/11; CBS, 3.9/10; ABC, 3.6/10; NBC, 1.8/5; Univision, 1.6/4; CW, 1.0/3.

In total viewers: ABC, 15.7 million; CBS, 11.4 million; Fox, 11.2 million; NBC, 5.9 million; Univision, 3.9 million; CW, 2.1 million.
