In an August in which the big ratings story is Time Warner Cable’s shut-out of CBS in more than 3 million homes, CBS was understandably proud as punch this morning that Under The Dome remained Monday’s only program to clock viewers in the double digits 10.3 million viewers. Dome topped the night’s nearest competitor, NBC’s American Ninja Warrior, by more than 5 million viewers. Dome logged a 2.4 rating in the demo which, CBS noted, is unchanged from last week — no surprise, given that CBS was locked out of TWC homes last week as well.

Armed with Dome, CBS finished Monday in first place in the demo (1.4 rating) and with viewers of all ages (6.2 million).

Speaking of American Ninja Warrior, it was way out in front from 8-9 PM, with 5 million viewers and a 1.5 demo rating. NBC noted the show has grown from its first half hour to its second in all seven telecasts this summer, which is to say it’s performing like a TV show should, at 8.

The 9 PM hour belongs to NBC’s Get Out Alive With Bear Grylls in the demo (1.2 rating) (though it was down 14% from the previous week) and CBS’ comedy reruns 2 Broke Girls (4.2 million viewers) and Mike & Molly (4.5 million).

At 10, Dome smothered its ABC and NBC competition combined, demographically and in total viewers. ABC’s 10 PM drama Mistresses was back after a two-week pre-emption to dominate NBC’s Siberia in the hour, though the pre-emption cost Mistresses 17% in the demo which left it in a tie with its smallest rating to date. ABC notes the soap improves its slot over a year ago with original programming, by 43% in the demo and 75% in viewers. And NBC points out Siberia is up, week to week, in total viewers — flat in the demo — and scored some of its best numbers in about a month.
