Crossover setup episodes on "Grey's Anatomy" and "Private Practice" gave ABC a win Thursday night, while Fox's "Bones" continues to perform strongly in its new Thursday timeslot.

ABC's "Grey's" paired up with a new "Private Practice" for overlapping plotlines to set up a crossover night next week. "Grey's" was up a tick from its last original airing two weeks ago to log the show's highest-rated telecast in 11 weeks, pulling in a 5.8 rating/14 share among adults 18-49, according to preliminary Nielsen Co. numbers. "Private Practice" was up 89% from its telecast last week, when it followed a "Grey's" repeat. Last night's episode scored its highest rating ever and comes in as the show with the strongest "Grey's" audience retention, keeping 91% of the demo's rating. At 8 p.m., a new episode of "Ugly Betty" posted a new season low and its lowest performance since last May, giving the network an average 4.5/12 and 11.8 million viewers.

Fox's "Bones" came in as the No. 1 show in the 8 p.m. hour, up 7% from its time-period debut two weeks ago. "Hell's Kitchen" dropped 27% from its season premiere last week after a special Thursday edition of "American Idol." Fox finished the night second with an average 3.3/9 (9.2 million).

New episodes across the board gave NBC third place for the night (2.9/8, 6.7 million). Facing strong competition from Fox and ABC, all of NBC's shows were down from their last original episodes two weeks ago. "My Name Is Earl" and "The Office" were both down 7% (surprising for "The Office" after its post-Super Bowl exposure Sunday night), "Kath & Kim" was down 9%, "30 Rock" dipped 6% and "ER" slipped 13%.

CBS aired comedy repeats in the 8 p.m. hour followed by encores of "CSI" and "Eleventh Hour," finishing fourth for the night with a 2.2/6 (8.6 million).

On The CW, new episodes of "Smallville" and "Supernatural" were down 6% and 19%, respectively, from last week to score an average 1.5/4 (3.6 million) for the night. Among women 18-34, the network posted a 1.2 rating.

*Ratings are specified in the 18- to 49-year-old demographic and viewership in P2+.

A note about ratings: Ratings are expressed as percentages of Nielsen's estimated 114.5 million U.S. television households. The first number, the rating, is a percentage of households tuned into a specific program at a specific time.

The second number, the share, is a percentage of households with televisions in use tuned into that same program. For example, if a show obtains a 10.2/16, this means that 10.2% of all U.S. households tuned into the program at some point during the broadcast. Meanwhile, 16% of all households watching television during the time period viewed the program at some point. Ratings are broken down further by demographic, as networks sell advertising time based on the makeup of the audience.
