Ratings Chart Attack!

ABC’s “Dancing With the Stars” waltzed into a tie for the No. 2 program of Monday night, yet it dipped to a series low.

“Stars” pulled down a 4.0 rating/11 share in the 18- to 49-year-old demographic, according to preliminary Nielsen research. The rating fell 18% from last week to the show’s lowest rating to date, excepting specials.

Second-place ABC (3.4/9) ended the night with “Samantha Who?” (3.0/7, a 12% dip week-to-week) and “The Bachelor” (2.5/7), which was flat.

CBS was the night’s winner, edging out ABC with a 3.6/9. “Two and a Half Men” (5.3/13) beat its closest competitor by 33%. Tied with “Stars” for the night’s No. 2 show, “Rules of Engagement” (4.0/10) returned last night to near pre-strike numbers, off 5% from its last original airing in November.

“The Big Bang Theory” (2.9/8) landed within striking distance of its previous original airing two weeks ago, while “How I Met Your Mother” (3.4/9) tumbled 15% from its last airing.

A two-hour “Deal or No Deal” (2.9/7) tied last week’s hourlong counterpart on NBC (2.9/8). “Medium” (3.1/8) dropped 11%.

Fox’s “New Amsterdam” finished its run last night, capping the season with a 2.1/5, right around its previous season average. “Bones” (2.8/8) shuffled into the 8 p.m. slot, bumping “House” repeats. The move improved the time slot’s previous four-week average by 17%. However, “Bones” posted its second lowest rating ever as a result of the move.

Fox ended up fourth with a 2.5/6.

An original “One Tree Hill” (1.3/3) in its new time slot did well for The CW, with a 2.0/5 rating in the 18-34 demographic. “Hill” posted a network high in the 18-34 demo in the Monday 9-10 p.m. time slot. A “Gossip Girl” repeat led off the night.

The CW ended the night with a 1.0/2 (1.3/4 in the 18-34 demo).
