NEW YORK (AP) — Through three weeks, viewership for National telecasts of NFL games is down 11 percent this season compared to 2016, the Nielsen company said on Tuesday.

The NFL Ratings are in focus because of President Donald Trump’s suggestion that viewers are turned off by a protest against police brutality that began with quarterback Colin Kaepernick refusing to stand for the national anthem.

Next week’s ratings will be even more closely watched, since conservative groups and Fox News Channel’s Sean Hannity have called for people angered by the protests to boycott this weekend’s games.

Meanwhile, Round One of the new ideological battle on cable television news went to Hannity, who has moved to a time slot directly competing with MSNBC’s Rachel Maddow.

The end of summer has to be sad for NBC, which has dominated in network ratings due to the success of “America’s Got Talent.” The show’s finale last week was seen by 15.6 million viewers, its biggest audience for a season-ender since 2010.
