NBC won among the broadcasters in key demos Sunday behind “Little Big Shots” and “Dateline,” while Fox got a boost from the return of an original “Family Guy” for the first time in more than a month. Also returning for the first of its final four episodes was CBS’ “The Good Wife,” which was on par with its most recent first-run.

According to preliminary national estimates from Nielsen, NBC’s “Little Big Shots” (1.8/6 in 18-49, 10.6 million viewers overall) was the No. 1 broadcast show of the night in 18-49, 25-54 (2.5/7) and total viewers — even if it was down 10% (0.2) week to week to match its low. It more than doubled its lead-in from a repeat of the program at 7 (0.8/3 in 18-49, 5.1 million viewers overall).

The Peacock experimented with “Crowded” at 9 p.m., airing new episodes both then (1.2/4 in 18-49, 5.5 million viewers overall) and its regular 9:30 p.m. slot (1.0/3 in 18-49, 4.3 million viewers overall). Given an expected downtick in the finals, that would leave the 9 p.m. “Crowded” on par with last week’s “The Carmichael Show,” which did have a slightly higher “Big Shots” lead-in. NBC closed things out with “Dateline” (1.2/4 in 18-49, 5.9 million viewers overall), which led its 10 p.m. hour among the broadcasters.

At CBS, “60 Minutes” (1.0/4 in 18-49, 10.2 million viewers overall) won the night’s opening hour in most categories, and was followed by “Madam Secretary” (0.9/3 in 18-49, 9.6 million viewers overall), which will need an upward adjustment in the finals (currently at 0.95, so it’s possible) to avoid a series low but nevertheless was the night’s most-watched scripted program overall. “The Good Wife” (0.9/3 in 18-49, 8.5 million viewers overall) matched its low, but stayed narrowly ahead of ABC’s “The Family” in 18-49, but “Elementary” looked shaky closing out the night (0.7/2 in 18-49, 5.6 million viewers overall). The Eye finished second for the night among the broadcasters in adults 25-54 and won the night in total viewers.

ABC was about average with “America’s Funniest Home Videos” (0.9/4 in 18-49, 4.5 million viewers overall), “Once Upon a Time” (1.1/4 in 18-49, 3.7 million viewers overall), “The Family” (0.8/2 in 18-49, 3.0 million viewers overall) and “Quantico” (1.0/4 in 18-49, 3.6 million viewers overall), with “Once” and “Quantico” losing a tick after rising last week. “The Family” remains low-rated, but at least has stabilized and grown in some categories in recent weeks; last night’s rating in women 18-34 (0.7/3) marked the show’s best score since its Sunday premiere on March 6.

Fox remained historically low leading off the night, with originals of “Bordertown” and “Cooper Barrett’s Guide to Surviving Life” both down a tick to a 0.4 in 18-49 and a little over 1 million total viewers. “The Simpsons” followed at 8 p.m. with a repeat (0.9/3 in 18-49, 2.0 million viewers overall), and a new “Bob’s Burgers” (1.0/3 in 18-49, 2.2 million viewers overall) was down a tick from last week when it enjoyed a first-run “Simpsons” lead-in. The net then spiked at 9 p.m. with “Family Guy” (1.4/4 in 18-49, 3.0 million viewers overall), which was in line with its last original of March 13, and “The Last Man on Earth” was steady at 9:30 (1.1/3 in 18-49, 2.5 million viewers overall)
