ABC performed a ratings alley-oop Thursday night with the NBA Finals and "Jimmy Kimmel Live."
Game 1 of the hoops showdown between the San Antonio Spurs and Miami Heat dominated broadcast television, earning an overnight rating of 10.4, according to Nielsen.
Viewership was down slightly from last year's Game 1, which earned a 10.6.
That basketball action boosted Jimmy Kimmel, who scored a rating of 3.1 in Nielsen's 56 metered markets, reaching its second highest rating this season, behind "Jimmy Kimmel Live: Behind the Scandalabra" last month.
Kimmel also earned a rating of 1.5 among key 18-to-49-year-olds, based on Nielsen's 25 local people meter markets.
That put Kimmel ahead of Jimmy Fallon's "Tonight Show" in both measures for the first time ever.
Precise viewership and demographic figures for the Spurs-Heat game won't be available until later Friday because Nielsen's "fast affiliate" numbers don't adjust for time zones, and the game started before prime time on the West Coast and after on the East Coast.
Still, it's safe to say ABC dunked over the competition, averaging 10.6 million viewers across prime time and earning a rating of 4.2 in the 18-49 demographic, in which a ratings point equals about 1.3 million viewers. In 18-49, ABC beat the combined rating for Fox, NBC, CBS and the CW.
Fox's "Hell's Kitchen" held on despite the NBA competition, drawing a 1.6 in 18-49 — flat from a week ago. "Gang Related" continued to struggle, falling a tenth of a point week-to-week to a 0.8.
