New gameshow “Identity” opened to good ratings Monday night, topping the other broadcast nets and holding on to all of its young-adult lead-in from “Deal or No Deal,” according to preliminary Nielsen nationals.

After “Deal or No Deal” won as usual in the night’s opening hour (4.4 rating/12 share in adults 18-49, 15.3 million viewers overall), “Identity” delivered a solid 4.4/11 in the demo and 12.2 million viewers overall, beating the mostly repeat competish on the other nets. The Peacock’s new gamer will air at 8 o’clock the rest of the week in a one-week tryout — a skedding scenario similar to that for “Deal,” which launched at this time a year ago.

Second-place CBS, whose program averages could come down in nationals due to an NFL preemption on its Cincinnati affiliate, was paced by repeats of “CSI: Miami” (3.9/10 in 18-49, 12.3 million viewers overall) and “Two and a Half Men” (3.4/9 in 18-49, 11.0 million viewers overall).

Fox was led by a special repeat of “House” at 8 (2.5/7 in 18-49, 7.6 million viewers overall), ABC by a repeat of “Wife Swap” (2.4/7 in 18-49, 6.6 million viewers overall). The Alphabet’s 10 o’clock drama “What About Brian” continues to struggle, logging its lowest firstrun averages to date (2.0/5 in 18-49, 4.5 million viewers overall).

Preliminary 18-49 averages for the night: NBC, 3.5/9; CBS, 3.0/8; ABC, 2.3/6; Fox, 2.3/6; Univision, 1.7/4; CW, 0.8/2.

In total viewers: NBC, 10.7 million; CBS, 9.4 million; Fox, 6.9 million; ABC, 5.9 million; Univision, 4.0 million; CW, 2.1 million.
