As one of the 20th century's most respected and influential people, Billie Jean King has long been a champion for social justice and equality. She created new inroads for both genders in and out of sports during her legendary career and she continues to make her mark today. She was honored on August 28, 2006, when the National Tennis Center, home of the US Open, was renamed the USTA Billie Jean King National Tennis Center.

In 1974, King co-founded World TeamTennis and has remained heavily involved with the league throughout its 42 seasons. In March 2017, King sold her majority ownership stake of World TeamTennis to Ein and Luddy. King remains a minority owner of WTT and currently owns the Philadelphia Freedoms and heads up the Billie Jean King Leadership Initiative. She also serves on the executive boards of the Women's Sports Foundation (which she founded) and Elton John AIDS Foundation (EJAF).
