How Tennis Led The Way for Equal Pay

Despite achieving a record-breaking victory at the 2015 FIFA Women's World Cup, the U.S. women's national team received much less money than their male counterparts who didn't even come out on top during the FIFA Men's World Cup in 2014.

Luckily, unequal pay doesn't exist among all sports.

Thanks to many athletes who shared the same vision, professional men and women tennis players receive equal prize money. In 2007, Wimbledon became the last Grand Slam tournament to shake off its stodgy gender bias and equalize prize money, reports Fortune.

The battle for equal pay began decades ago when Billie Jean King created the Women's Tennis Association.

At the time, her and 63 other female tennis stars fought behind closed doors in order to institute equal pay among all players. They would congregate late into the night, while balancing their tennis matches. Their efforts yielded positive results when the U.S. Open became the first tournament to give men and women equal pay in prize money.

That same year in 1973, King accomplished another milestone for gender equality when she beat Bobby Riggs in the famous Battle of the Sexes match. 

Hopefully, by the time the next Women's World Cup rolls around, women will be earning equally as much as men.
