NFL TV viewership fell last season for the first time in four years — and you can’t blame Donald Trump or Hillary Clinton for the slide.

Sure, the number of people tuning into NFL games fell 14 percent through Week 9 of the 2016 season — which ended a day before Election Day — but they were also marginally lower in the last eight weeks of the season, a report Monday from Drexel Hamilton media analyst Tony Wible and stats from Nielsen reveal.

Overall, average TV viewership for the 2016 NFL season fell 8 percent, to 16.5 million people, from 17.9 million the previous year.

It was the steepest dropoff in viewers in the past 10 years — and only the third down year since 2007.

To be sure, the 2015 NFL season drew an average of 17.88 million viewers a game — the highest average audience in a decade.

“The season’s overall volatility may suggest ratings are near an inflection or peak,” Wible wrote.

There has been speculation that the televised presidential debates and the otherwise contentious political race stole attention from the NFL games.

Others pointed to too many commercials during games, noncompetitive games, three prime-time nights of NFL a week and a riveting World Series game during Week 8 as other reasons for the drop in viewers.

Wible did not say why he thought NFL ratings were near a peak, but said the diversions were not the reason.

In all, an average of 2.3 million viewers returned to watch NFL games after Election Day.
