Viewership for the first two games of the series between the Golden State Warriors and Toronto Raptors was down sharply from last year's finals — 28 percent for the first game and 29 percent for the second, the Nielsen company said.
While LeBron James fans may point to the star's absence, geography likely accounts for most of the drop. Toronto's television audience is not included in the Nielsen ratings, since it's out of the U.S. Missing one team's fan base is a huge hurdle for ABC.
It's Golden State's fifth straight appearance in the finals, while Toronto is there for the first time.
The most hopeful sign for ABC is that the teams split the first two games, raising the possibility of a long series. Viewership traditionally increases with competitive series.
The surest sign that summer is near is the return of NBC's "America's Got Talent," which was the top non-sports program of the week.
Behind the basketball, ABC won the week in prime time, averaging 5.4 million viewers. NBC had 3.92 million, nipping CBS and its average of 3.91 million. Fox had 2 million viewers, ION Television had 1.4 million, Univision had 1.3 million, Telemundo had 1.1 million and the CW had 650,000.
