Among adults who said that they follow at least one sport, 36 percent chose professional football as their favorite. Major League Baseball came in second at 13 percent. The gap between football and baseball widened, from 14 percentage points in the 2011 poll to 23 percentage points in this year’s survey. That 23-point gap is the largest disparity between the No. 1 and No. 2 sports since the poll’s inception in 1985. Professional football has been selected as the most popular sport in each year since the poll began.
