NBC’s “The Voice” came back to earth on Tuesday, but remained the night’s top program among young adults and helped propel lead-out comedies “About a Boy” and “Growing Up Fisher” to timeslot victories in key demos. With CBS in repeats, the dramas on ABC and NBC were on the upswing, including the Peacock’s victorious “Chicago Fire” closing out the night.

NBC won the night in all key demo categories and finished a close second in total viewers to CBS. Fox placed fourth in both categories.

According to preliminary national estimates from Nielsen, “The Voice” averaged a 3.4 rating/12 share in adults 18-49 and 13.1 million viewers overall in the 8 o’clock hour — still 5 shares better than anything else in its timeslot but down about 15% from last week’s score, which marked the show’s best Tuesday rating since October. The first week of Daylight Saving Time was likely a factor in the decline for the music contest, which remains in its blind-auditions round.

Following the night’s top show, “About a Boy” (2.1/6 in 18-49, 7.9 million viewers overall) declined about 15% from last week but led its timeslot in demos, and “Growing Up Fisher” (1.8/5 in 18-49, 6.5 million viewers overall) was down just a tick and handily beat its comedy competition in 18-49. Closing things out, “Chicago Fire” (2.0/6 in 18-49, 7.3 million viewers overall) was up slightly from last week, likely picking up some viewers from CBS, whose “Person of Interest” went into repeat; the second-year drama drew its largest overall audience since December.

For NBC, its 17 first-place finishes on Tuesday in adults 18-49 is more than it’s had at this point of the season in the history of Nielsen People Meters.

ABC was up week to week, with “Marvel’s Agents of SHIELD” (second-place 2.0/7 in 18-49, 5.8 million viewers overall) taking advantage of a repeat “NCIS” to rise 11% (and perhaps 17% in the nationals with an expected uptick to 2.1). In the 9 o’clock hour, “The Goldbergs” (1.5/5 in 18-49, 4.3 million viewers overall) held steady from last week, finishing closer to “About a Boy” and moving ahead of Fox’s “New Girl” after tying it last week. ABC also saw gains for its struggling comedy “Trophy Wife” (0.9/3 in 18-49, 2.9 million viewers overall) and drama “Mind Games” (0.9/3 in 18-49, 2.5 million viewers overall).

It was a slow night for Fox, whose “Glee” (0.9/3 in 18-49, 2.3 million viewers overall) dipped to another low. That made it harder for “New Girl” (1.3/4 in 18-49, 2.4 million viewers overall) and “Brooklyn Nine-Nine” (1.2/3 in 18-49, 2.5 million viewers overall), were down 20% and 8% respectively.

CW’s “The Originals” (0.9/3 in 18-49, 1.9 million viewers overall) was up slightly to tie “Glee” in 18-49, but the gain could be due to a Bulls basketball game being included in the net’s early average in Chicago. It was followed by a repeat of “Supernatural” (0.6/2 in 18-49, 1.4 million viewers overall).

Preliminary 18-49 averages for the night: NBC, 2.4/8; ABC, 1.4/4; CBS, 1.3/4; Fox, 1.1/3; Univision, 1.0/3; CW, 0.7/2; Telemundo, 0.5/2.

In total viewers: CBS, 9.4 million; NBC, 9.2 million; ABC, 4.0 million; Univision, 2.6 million; Fox, 2.4 million; CW, 1.6 million; Telemundo, 1.3 million.
