Michael Weatherly and Cote de Pablo, NCIS

This Tuesday's tallies:

8 pm/ET
NCIS was the evening's most-watched program, delivering 18.79 million total viewers — a 10 percent increase over its last (impressive) outing, and the series' largest audience ever. That deserves its own paragraph, frankly.

House won the demos, but placed second with 12.88 mil (dipping 135K). Trailing the DWTS recap (10.4 mil) and Biggest Loser (8 mil), 90210 netted 2.73 mil, a week-to-week drop of 290K.

9 pm
The Mentalist enjoyed a gain of 350 thou to achieve another series high, 16.46 million viewers. That gave the freshman drama a "W" in total audience and demos, besting Dancing with the Stars' results show (16.39 mil) on both counts. Fringe placed third with 8.88 mil (down 220K from its last fresh eppy), while People's Choice Award nominee Privileged slipped to 1.87 mil.

10 pm
Without a Trace was No. 1 in viewers (12.2 million), while SVU (9.42 mil) led the demos. Eli Stone delivered 7.44 mil, dipping 230K from its last outing and particularly crippled by an erosion of more than two million heads over its hour run.
