All of the Big Four professional sports leagues would love to truly tap into the female market, but the NFL appears to be the only one that’s making strides. The NFL has more regular female viewers than the NBA and Major League Baseball, according to Nielsen, and more women actually watched the Super Bowl than either the Grammy Awards or the Academy Awards last year. In turn, the NFL has released a number of ads for NFL merchandise and apparel featuring women and, most interestingly, moms. One existential problem for the league is that the growing concern over concussion-related injuries will make mothers think twice about allowing their kids to play the sport.
