With Browns games a noted exception, NFL preseason ratings took a hit this year. NFL preseason games averaged 2.35 million viewers across NBC, CBS, FOX, ESPN and NFL Network, down 9% from last year (2.57M), but up 4% from 2016, when several games aired opposite the Summer Olympics (2.27M)... Outside of the Browns, preseason viewership largely declined. Of the 14 non-Browns games that can be compared to last year, only three* posted an increase in viewership. With Browns games excluded, preseason viewership fell 18 percent from last year (2.85M to 2.32M) — double the overall decline.
