Game 7 of the NBA Finals on ABC Sunday night averaged 30.8 million viewers, making it the most-watched NBA game since Game 6 of the 1998 Finals, in which Michael Jordan won his final championship for the Bulls over the Jazz. That game averaged 35.9 million viewers.

This time the star attraction was the Cavaliers’ LeBron James, who led his team to a 93-89 victory over the Warriors and the first championship in franchise history.

The game also was the highest-rated game since that 1998 finale based on household rating, averaging 15.7 percent of American homes.
