NBC’s Little Big Shots continues to be the big news on Sunday nights, though CBS dominated primetime overall in total viewers and the demo.

NBC’s kiddie talent series was the night’s No. 1-ranked primetime telecast among Big 4 broadcasters in the demo (2.0 rating) and overall audience (12.1M), excluding CBS’ Masters golf overrun. The series climbed 11% week-to-week in the demo and 6% in overall audience, marking its second week of total-viewer climb.

The Steve Harvey-hosted LBS built by 150% on its lead-in — an LBS encore — among adults 18-49 (2.0 vs. 0.8), and 108% in total viewers (12.1 million vs. 5.8 million). The reality ratings gem is up 100% versus NBC’s time slot average this season prior to its debut (2.0 vs. 1.0), excluding sports and trophy shows, and 181% in overall audience (12.1M vs. 4.3M).

At 8 PM, the moppets managed to edge out sports-overrunning CBS, and at 8:30 the tots clobbered eye network’s Madam Secretary’s late start. That sophomore drama nonetheless finished the night the top scripted broadcast in viewers, with an average of 9.4M, and in the demo (1.1), which was flat compared to its previous regularly scheduled episode March 20.

The 7 PM hour appears to have been controlled by CBS (2.1, 12.8M) with its golf tourney and newsmag 60 Minutes, last night featuring a segment on China’s exploding film industry. Those ratings are tentative and subject to change, owing to the live sportscast. (From  7:30-8:30 PM, the newsmag averaged 11.75M and 1.6 in the demo, early stats show.)

At 9 PM, dueling comedies on NBC and Fox tied in the demo with 1.1 ratings each, including NBC’s The Carmichael Show (1.2, 5.7M) and Crowded (1.0, 4.3M), as well as Fox’s Family Guy repeat (1.2, 2.5M) and The Last Man on Earth (1.1, 2.7M).

CBS took the hour in total viewers with a drama mash-up of Madam Secretary overun and Elementary, clocking a collective 7.7M viewers (and a 0.9 rating in the demo).

At 10 PM, CBS’ Elementary took the hour in tonnage (5.8M viewers), while NBC’s Dateline won on the demo (1.1, 4.8M viewers) with a report about twin sisters who find their mother murdered in their Georgia home.

CBS emerged from the primetime skirmish with a winning 1.3 rating and 9.3M viewers. NBC followed closely in the demo (1.2) and not so in total viewers (6.9M). ABC followed with a 1.0 demo rating and 3.8M viewers, followed by Fox’s 0.9 rating and 2.1M viewers.
