The Black Lives Matter protests continue to influence the spectacle and the business of pro sports. With many of the world's top leagues now back in action, including the NBA, football and the NFL, how are they accommodating athletes who want to campaign for social change? Meanwhile the International Olympic Committee's in the process of reviewing its January ban on political protest gestures (including kneeling, hand signs and the wearing or holding of placards or armbands) before the rescheduled Tokyo Games take place in 2021. To put modern events into historical context is sociologist Professor Douglas Hartmann, the Chair of Sociology at the University of Minnesota. He is the author of Race, Culture, and the Revolt of the Black Athlete: The 1968 Olympic Protests and Their Aftermath.
