The NFL's television ratings for the 2017 regular season fell by 9.7 percent.

A typical game was watched by 1.6 million fewer people this season as compared to last season (14.9 million vs. 16.5 million).

The NFL had an eight percent slide during the 2016 season.

Both Fox CEO James Murdoch and CBS Sports Chairman Sean McManus blamed the ratings slide on the proliferation of games.

The NFL RedZone may also be taking fans away from watching the daytime games on CBS and FOX.

The NBA, however, has seen a 20 percent increase in viewership this season as compared to 2016-17.

Nielsen data, however, also shows that the 20 of the top 30 highest rated shows on television in 2017 were football games.
