UPDATE, 10:08 AM: Looks like the fast nationals for last night’s America’s Got Talent (3.7/10 in 18-49) actually tied with the Live+Same Day rating for the show’s May 14 premiere for a season high among adults 18-49. Since the talent reality show is often adjusted up in the finals — as was the case May 14, when it drew a 3.6 in the fast nationals, last night’s episode could very well post a new season high when ratings are released this afternoon. Among total viewers, last night’s show hit an outright  total viewership high.America's Got Talent Ratings

PREVIOUS, 9:04 AM: Maybe it was Howard Stern finding his stride or maybe it was the St. Louis-based auditions, but with a mix of repeat and new show, America’s Got Talent hit a season high Tuesday. NBC’s 8 PM repeat showing of Talent (2.0/6) provided the lead-in to a new episode (3.7/10) at 9 PM. The latter was up 12% from last week, with the Midwest auditions garnering 11.3 million total viewers. NBC finished off primetime with a Grimm (1.3/3) repeat. NBC won the night in the adults 18-49 demo.

On ABC, the 8 PM season finale of Cougar Town (1.2/4) was up 20% from its series low two weeks ago, drawing 3.5 million total viewers. At 9 PM, ABC went jubilee with the special ABC News: The Real Queen By Her Own Royal Family (1.3/4). CBS went back-to-back with NCIS repeats. The 8 PM NCIS (1.4/4) flowed into the 9 PM NCIS: LA (1.3/4), and the network ended the night with 48 Hours Mystery (1.4/4). Fox aired four New Girl (1.0/3) repeats from 8-10 PM.
