On this day, September 20, 1973, Billie Jean King beat Bobby Riggs in a highly publicized “Battle of the Sexes” tennis match. The match was held at the Houston Astrodome, between 55-year-old Bobby Riggs and 29-year-old Billie Jean King. She won in three sets.

The match was viewed by an estimated 90 million people around the world. King felt the weight of women’s rights on her shoulders, saying “I thought it would set us back 50 years if I didn’t win that match. It would ruin the women’s tour and affect all women’s self-esteem.” Read more (Wikipedia)
