Ratings for the NFL are down to begin the 2016 season, continuing a year-wide trend in the sports industry.

“Sunday Night Football,” television’s highest-rated prime-time show for five years running, has seen a 10 percent viewership drop so far this season. Cable’s top sports property, “Monday Night Football,” is down 19 percent.

Ratings for the Olympics were down, as were ESPN's "Sunday Night Baseball" series.

The NBA and college football have seen increases.

“All these sports go through cycles,” said Artie Bulgrin, ESPN’s senior vice president of global research and analytics. “It’s impossible to suggest that there’s anything going wrong here, particularly in light of the fact that we are in a really odd year in terms of the protracted presidential race, which has captured the attention of Americans going back a year now. Plus, it’s an Olympic year, which clearly had an impact during the summer.”

Even with the decline, sports programming still dominates television ratings.

Last year, 93 of TV’s top 100-rated shows were live sports programs. Ten years earlier, in 2005, live sports accounted for only 14 of the top 100.

The election could also be playing a role in sports ratings.
