CBS ruled each of Tuesday’s primetime hours in key demos behind its crime dramas ”NCIS,” ”NCIS: Los Angeles” and ”Unforgettable,” while Fox ran second as ”New Girl” held steady at its recent level but ”Glee” continues to wobble.

According to preliminary Nielsen national estimates, ”NCIS” (4.0/11 in 18-49, 19.9 million viewers overall) was down a tad week to week but up a bit year to year, and again was the night’s No. 1 program in 18-49, 25-54 and total viewers. ”NCIS: Los Angeles” (3.3/8 in 18-49, 15.0 million viewers overall) also led its hour in key demos, as did 10 p.m. rookie ”Unforgettable” (2.4/6 in 18-49, 11.2 million viewers overall), which featured guest star Marilu Henner and was up over last year’s ”The Good Wife.”

CBS edged out Fox for the night’s lead in 18-49 and won by sizable margins over ABC in both adults 25-54 and total viewers.

At Fox, ”Glee” (2.9/8 in 18-49, 7.1 million viewers overall) was down slightly week to week but off about 40% vs. the comparable night a year ago; it ran second for its 8 p.m. hour in 18-49, but wasn’t that far ahead of ABC’s ”Last Man Standing” in the night’s opening half-hour. It was followed by ”New Girl” (3.5/9 in 18-49, 6.9 million viewers overall), which matched last week’s score and narrowly led its 9 o’clock half-hour in 18-49 while standing as the night’s top program in 18-34 (3.9/11). And at 9:30 p.m., ”Raising Hope” (2.2/5 in 18-49, 4.8 million viewers overall) was up a tick week to week.

ABC was in line with last week from 8 to 10 p.m. with half-hours ”Last Man Standing” (2.6/7 in 18-49, 9.0 million viewers overall), ”Man Up” (1.7/4 in 18-49, 6.3 million viewers overall) and the ”Dancing With the Stars” results show (2.7/7 in 18-49, 15.0 million viewers overall). Net’s best news came at 10 p.m., where second-year crime drama ”Body of Proof” (2.1/6 in 18-49, 9.8 million viewers overall) returned from a one-week preemption to post some of its best scores of the fall; even if it falls a tick in the nationals as expected, that would still put it up over last year’s ”Detroit 187,” which did a 1.7 demo score coming out of a stronger ”Dancing” result show (3.4).

At CW, ”90210” (0.7/2 in 18-49, 1.6 million viewers overall) could be benefiting from the declines of ”Glee,” as it had its most watched episode of the season. And at 9, rookie drama ”Ringer” (0.7/2 in 18-49, 1.9 million viewers overall) drew its largest overall audience since its series premiere.

Preliminary 18-49 averages for the night: CBS, 3.2/8; Fox, 2.9/8; ABC, 2.3/6; NBC, 2.0/5; Univision, 1.4/4; CW, 0.7/2.

In total viewers: CBS, 15.4 million; ABC, 10.8 million; Fox, 6.5 million; NBC, 5.8 million; Univision, 3.4 million; CW, 1.7 million.
