“America’s Got Talent” continued its run near the top of the summer ratings leaderboard, helping NBC to yet another comfortable win on Tuesday night.

The talent competition delivered a 1.3 rating among adults 18-49 and 8.6 million viewers, almost exactly the same numbers as last week. Right after, “World of Dance” tripped up a fraction, ticking down to a 0.8 rating and 4.3 million viewers (last week’s episode managed a 0.9).

On a rerun heavy night, “DC’s Stargirl” aired a new episode to a 0.2 rating and just under 1 million total viewers, which represents a small audience uptick for the CW series. Last week, the network’s “Happy Hour” program scored a rare, undesirable 0.0 rating, but this time around it did register a 0.1, drawing 488,000 pairs of eyeballs in the process.

“The Genetic Detective” broke its streak of 0.4 ratings, with its fifth episode dipping to a 0.3 for the first time. 2.2 million viewers tuned in to the new episode on ABC, a 20% dip from last week. The Disney-owned network kicked off the night with back to back replays of “The Conners,” the first of which scored a 0.4 and the second a 0.3. Reruns of “Black-ish” and “Mixed-ish” also came in with a 0.3.

Over on CBS, an “NCIS” replay led the way at a 0.5 rating and 5.6 million viewers. Replays of “FBI” and its spinoff “FBI: Most Wanted” both came in at a 0.4 rating, and averaged around 4.5 million viewers between them.

Finally on Fox, Gordon Ramsay cooked up a 0.4 rating in both time slots, with a “Hell’s Kitchen” replay at 8 p.m., followed by a “24 Hours to Hell and Back” rerun at 9 p.m. Both shows drew around 1.4 million viewers.
