America’s Got Talent topped Tuesday in primetime, delivering a 0.7 in the adults 18-49 demographic and 5.58 million viewers to hold steady with last week’s numbers. The reality talent competition led into Night 2 of the Republican National Convention, which so far trails Night 1 in the early data with NBC (0.3, 2.42M) and ABC (0.3, 1.74M) leading in the demo and CBS (0.2, 1.30M) at No. 3. These numbers will likely be adjusted when finals are delivered.
That’s up slightly from the Day 1 on the broadcast networks. On Day 1, ABC had 2.0 million, NBC had 1.7 million and CBS had 1.5 million for a total of 5.2 million, or about a 5% increase.

The Republican’s 5.46 million for Day 2 on the broadcast channels is a little more than 1.1 million short of the Democrats’ 6.64 million with the broadcast channels for Day 2.
