ABC earned a 15.0 overnight Nielsen rating for Game 6 of the NBA Finals on Sunday night, meaning that 15 percent of homes with a television in 56 U.S. markets watched the game.

The 15.0 marks the highest overnight rating ever for a Game 6 on ABC, as well as a 22% increase from a 12.3 for Lakers-Celtics Game Six last year, which aired on a Tuesday night.

Sunday night’s telecast is also up 35% from an 11.1 overnight for Game 6 in 2006, which serves as an interesting comparison since that series also featured Dallas and Miami.
