Tuesday's tallies:

8 pm/ET
American Idol Rat-Packed in an audience of 22.54 million total viewers, dipping 700K week-to-week. Part 1 of NCIS' spin-off set-up scored second with 16.32 mil, a drop of 7 percent. 

The Biggest Loser averaged 9.43 mil over its two-hour run, its largest audience since Feb. 3. Lagging far behind ABC's According to Jims, Reaper plunged 26 percent, to 1.82 mil.

9 pm
The Mentalist topped the hour with 16.9 million viewers, up 155 thou from its last fresh outing. Dancing with the Stars' results show followed with14.27 mil. At 10.6 mil, Fringe was up a hair from last week.

90210, meanwhile, sank 19 percent to hit an all-time low of 1.8 mil. That's right, 90210 got a Season 2 pick-up in February, yet Privileged is on the bubble. Join me in some head-scratching.

10 pm
Without a Trace was No. 1 with an audience of 12.35 million (down 800K), but SVU (10.5 mil, surging 16 percent) dominated in the demos. In fact, Stabler and Benson copped their best 18-49 numbers since Jan. 6, and their second-best such demos of the season. 

ABC's Cupid targeted 6.16 mil, down 440K and suffering significant tune-out over the hour.
