During the first preseason game of the 2016 National Football League season, San Francisco 49ers Quarterback Colin Kaepernick took a knee during the playing of the national anthem. This in turn set off a series of protests that lasted the entirety of the 2016 and 2017 seasons until a policy was enacted in 2018, banning players from protesting. To determine the effect of the protests on game attendance and ticket prices, a differences-in-difference analysis was used with data on total and home attendance, ticket price, and protest type from the 2014 to 2018 NFL seasons. Controls were used for team winning percentage, political orientation, population, and median income of the home city. Protest types were split into three categories, ambiguous, unambiguous, and non-protesting, measured from season to season. It was found that there was a decrease in home attendance the following season for teams that unambiguously protested, and an increase in home attendance for those that ambiguously protested. Also, interacting the protest type with a political party indicator produced statistically significant results that followed the same trend as above, but at a much higher rate.
