CBS blew past broadcast competitors in overall audience, and took every time slot except one in the demo, thanks to a 7-8 PM overrun for the conclusion of golf’s The Masters.

That said, the final round looks to be a 13-year low, when final stats arrive. Prelim CBS stats will be subject to significant adjustments, what with its programs running at different hours in various time zones following the live-across-country sports broadcast. Fox, meanwhile, went all-encore Sunday night, while CW went local.

CBS’s Master Golf opened primetime with 16.13M viewers and a 3.1 demo rating at 7, and 13.93M viewers with a 2.6 demo rating at 7:30 PM.

Early morning stats showing a 11.06M viewers watched 60 Minutes at 8 PM, with its 1.5 demo rating pushed 36% above last week’s 1.1.

CBS’s lineup then began descending from that high altitude. NCIS: L.A. clocked 9.24M viewers; its 1.1 demo rating represents a drop from its 1.6 with its prior telecast two weeks earlier on March 26 when NCAA basketball gave it a big boost.  After NCIS: L.A. CBS’s  Madame Secretary logged 6.54M viewers with  a  0.7 demo rating that was  down compared to its 1.1 rating in its delayed 9:35 PM ET broadcast that same NCAA-fueled night.

ABC gathered 0.7 demo ratings with America’s Funniest Home Videos (4.584M viewers), Once Upon a Time (2.605M), and The Match Game (2.969M). After that, at 10 PM,  American Crime (1.733M) scored another 0.4 demo rating. Once Upon a Time’s 0.7 marked a new series low.

NBC’s 7 PM Little Big Shot rerun logged a 0.6 demo rating and 4.130M viewers. At 8 PM, an original Little Big Shots  (8.629M viewers, 1.3 demo rating) grew by 117% from its leadin in the demo, and by 8% compared to last week.

NBC’s 9 PM Chicago Justice fumbled some of that leadin, scoring 5.451M viewers and a 0.9 demo rating at 9 PM. At 10 PM,  Shades of Blue (3.989M viewers, 0.7 demo rating) tied for No. 1 in the time slot demo derby.
