Tuesday's tallies:

8 pm/ET
American Idol cued up another million total viewers week-to-week to top the hour with an audience of 26.28 mil. Trailing an NCIS repeat (14.36 mil), Biggest Loser averaged 10.5 mil over its two-hour run, shedding 500,000 viewers. Behind Homeland Security (5.68 mil), 90210 (2.44 mil) was up a hair. 

9 pm
A repeat of The Mentalist won the hour with a cool 15 million viewers. In second, Fringe scared up its second-largest audience ever — 13.04 mil, up 900K —and matched its best delivery in key demos. The takeway here? Encourage costars to secretly marry.

Averaging 4.8 mil across two episodes, Scrubs slipped 280 thou. Privileged inched up to 1.7 mil, its best audience since Nov. 11. 

10 pm
Without a Trace dropped 760K but still bested SVU, 12 mil to 10.32 mil. (SVU, though, was No. 1 in the demos.) The answer to ABC's What Would You Do? (5.8 mil, down 500K) increasingly seems to be, "Watch the other networks."
