Total viewership for Week 1 of the new NFL season came in at 113.97 million, down just 1 percent from the same week a year ago.

But the audience’s overall stability — as spread out over the week’s seven telecasts — belied erratic shifts in viewership by individual games.

Five of the seven contests recorded audience swings in excess of 9 percent, producing a range defined by a 28 percent upside for Sunday’s 1 pm game on CBS and a 13 percent downside for Thursday’s season opener on NBC.

Four of the seven telecasts failed to match the number of eyeballs drawn to the year-ago game, while the three that gained in viewership all aired on Sunday.

The overall decline represented the league’s third consecutive decrease in Week 1 viewership.

Last season’s opening seven games drew an audience that was 12 percent smaller than it was in 2016, which in turn was 7 percent smaller than the audience for the first seven games of 2015.

In 2015, thanks to an 4.4 percent uptick in viewership, the number of Week 1 viewers reached a peak of 140.4 million.

The loss in opening-week viewers since then is 23 percent.
