Back in 2010, the Wall Street Journal announced that their study of four game broadcasts, combined with analysis by other researchers, found that, quote, the average amount of time the ball is in play on the field during an NFL game is about 11 minutes, end quote.

Turns out the journal's study merely confirmed a scientific American investigation that we did

80 years earlier. While scrounging through our digital archives recently, I happened on the

article from our November 1930 issue titled How Many Minutes of Play in the Average Football

Game? Author Hugo L. Rush was the supervisor of the technical data section of the Johns Manville Corporation.

as well as Notre Dame, Army, Stanford, and Ohio State.

actually in play during those games was 12 minutes, 22 seconds. I'd guess that the tendency to use
