NBC’s “World of Dance” waltzed its way to one of the highest ratings, as NBC comfortably won Tuesday night.

The dance competition series scored a 0.9 rating (up from a 0.8 last time around) among adults 18-49 and drew 4.4 million total viewers. It was topped only by its “America’s Got Talent” lead-in which delivered a 1.3 rating and 8.4 million viewers. That’s the same rating as the last two episodes for the singing show, but a small 3% down tick in audience.

On a night with few other original offerings, a new episode of ABC’s “Genetic Detective” came in even at a 0.4 rating and 2.7 million viewers. Prior to that, the Disney-owned network aired an encore presentation of “Let It Fall: Los Angeles 1982-1992,” John Ridley’s acclaimed feature-length doc about the 1992 uprising in Los Angeles, to a 0.5 rating and 2.6 million pairs of eyeballs.

Over on the CW, “Stargirl” aired a new episode even at a 0.2 rating and 933,000 total viewers. That represents only the second time the DC show has dipped below 1 million Live+Same Day viewers. A rare occurrence cropped up in the network’s 9 p.m. time slot, as the CW’s “Happy Hour” registered a 0.0 rating, and drew only 309,000 viewers.

A replay of “NCIS” led the way for CBS with a 0.5 rating and 5.9 million total viewers. Reruns of “FBI” and its “Most Wanted” spinoff both scored a 0.4 rating, with the former drawing just under 5 million viewers, and the latter 3.9 million.

Finally on Fox, a replay of “Hell’s Kitchen” cooked up a 0.4 rating and 1.3 million viewers, followed by another Gordon Ramsay replay of “24 Hours to Hell and Back” at a 0.3 rating and 1.2 million viewers.
