The premiere of America's Got Talent posted the smallest 18-49 rating for a season opener in the show's history on Tuesday — but it still dominated primetime, improving slightly in total viewers from a year ago and helping World of Dance score a solid debut. The CW's Stargirl also held up well in its second week.

America's Got Talent scored a 1.4 rating among adults 18-49, which is down from 1.7 a year ago and is a premiere low for NBC's flagship summer series. Its 9.81 million viewers, however, is up a little bit over the 2019 debut (9.75 million), and that figure is more than 4 million viewers ahead of the next-most-watched show in primetime (an NCIS rerun on CBS with 5.66 million viewers).

World of Dance, meanwhile, debuted to a 1.0 in the 18-49 demographic and 5.15 million viewers, even in the demo with its third-season premiere (which aired in-season in February 2019) and up by about a million viewers. Tuesday's episode was the most watched for the show since the second-season finale in September 2018.

Stargirl retained nearly all of the audience from its premiere last week (1.18 million vs. 1.22 million) and was steady in adults 18-49 at 0.3. Legends of Tomorrow (770,000 viewers, 0.2 in 18-49) was steady as well. 

The premiere of ABC News series The Genetic Detective pulled in 3.21 million viewers and a 0.4 in the 18-49 demo. A Diane Sawyer news special at 9 p.m. drew about 2.6 million viewers and a 0.4 in the demo.

NBC's 1.3 rating in adults 18-49 easily led primetime. CBS and Univision tied for second at 0.5, just ahead of the 0.4 for ABC. Fox and Telemundo tied at 0.3, and The CW averaged 0.2.
