Living legend and lifelong activist Billie Jean King talks about what it takes to stand up and fight for equality, regardless of the circumstances. Fifty years ago, King and eight other female tennis players, known as the Original Nine, bravely put their careers and reputations on the line to fight for equal pay and equal footing for women's tennis, with the indispensable help of promoter Gladys Heldman, the founder and publisher of World Tennis magazine, and the groundbreaking sponsorship of Joseph Cullman III, the CEO of the Philip Morris Company. When the Original Nine signed symbolic one-dollar contracts to stage their first breakaway tournament in Houston, ignoring threats from the existing tennis establishment, it was the start of the pro tennis tour for women as we know it and paved the way for modern stars to earn tens of millions in career prize money today.
