A smaller dip, like the N.F.L.’s 13 percent, can be as simple as the average viewer going from watching 110 minutes a game to watching 96 minutes. They might not even know they are watching less than they were last year, and if they do know they might not be able to articulate why.
ESPN and other networks try to better understand fan viewing behavior through surveys and focus groups. But ultimately, anybody that tells you they know the reason viewership has changed is incorrect.
To begin, fewer people are turning on their televisions. Compared with September 2019, total viewership across all television was down 9 percent in September 2020, and 10 percent during prime time.
There are also standard cyclical trends that affected some sports. August 2019 viewership was down 9 percent from April 2019 viewership, as people watch less television in summer than in spring. This year, that hurt leagues like the N.B.A. and N.H.L., which typically end before the summer.
An unusually high number of games were also played early in the day — M.L.S. tried 9 a.m. Eastern weekday kickoffs — when fewer people watch. General viewership from 1 to 6 p.m. was 38 percent lower than prime time in August.
When sports have been played during the evening, they have faced unusually tough competition. Viewership of cable news in early October was up 79 percent compared with last year, an increase of four million viewers, no doubt because of the presidential election, the pandemic and related news.
There has also been increased competition within sports. The N.B.A. and N.H.L. normally have late spring to themselves. Baseball owns summer. The N.F.L. and college football dominate fall. Because of the abnormal schedules, however, their games were played simultaneously. On one Sunday in September, the N.F.L., N.B.A., M.L.B., N.H.L., M.L.S. and W.N.B.A. all had games — the first time that has happened.
