13. 'Venus Vs.' (Dir. Ava DuVernay)
The "IX" in the Nine for IX series refers to Title IX, the federal law that requires public institutions to provide equal opportunities for men and women to participate in extracurricular activities like athletics. The first Nine for IX episode details how Venus Williams carried on the fight of tennis legends like Billie Jean King before her to get equal prize money for both genders, swatting away the same maddening, nonsensical arguments against equality that forced Title IX into existence.
