The Season 12 penultimate episode of NBC’s America’s Got Talent on Tuesday night drew 14.3 million total viewers and a 2.9 rating in adults 18-49 (Live+same day) to deliver the long-running variety series’ most-watched Tuesday telecast in six years and the highest-rated among 18-49 in three years. UPDATE: In the finals released Wednesday afternoon, AGT was adjusted up to 14.7 million viewers and a 3.0 in 18-49.

Last night’s show edged last year’s performance finale by 4% in 18-49 (2.9 vs. 2.8) and 2% in total viewers (14.32 million vs. 13.97 million). It also surged (up 23% and 26%) vs. last week’s Tuesday episode, whose ratings were depressed because of a later air time for the hurricane telethon.

With a big AGT lead-in, The Paley Center Salutes the Best of Will & Grace special on NBC posted 5.3 million viewers and a 1.2 in 18-49 (adjusted down in the finals to 4.9 million and 1.1), topping the five previous Paley specials.

The only other original last night was ABC’s summer drama Somewhere Between (1.9 million, 0.4 in 18-49). It was up 16% in viewers from last week with its largest audience since the premiere and up a tenth in the demo vs. last week.
