Game 5 of the NBA Finals on ABC was once again the top program last night. The game, in which Dallas held off Miami’s fourth-quarter rally to win 112-103, delivered a 12.6 overnight household rating. And again, that was slightly down from last year’s Game 5 between the LA Lakers and Boston Celtics (12.8 rating) but higher than the corresponding games the previous six years, including the Heat-Mavericks face-off in 2006 (10.1 rating). ABC is projected to win Thursday night in total viewers and adults 18-49 when final ratings are released this afternoon. Airing against the game, Fox’s reality series So You Think You Can Dance (2.4/7) was down 17% from last week. The only other original offering last night, NBC’s burnoff dramedy Love Bites (0.9/2), was down a tenth from last week’s low-rated debut in the 10 PM slot.
