After his stint with the Conquistadors, Chamberlain successfully went into business and entertainment, made money in stocks and real estate, bought a popular Harlem nightclub, which he renamed Big Wilt's Smalls Paradise, and invested in broodmares. Chamberlain also sponsored his personal professional volleyball and track and field teams, and also provided high-level teams for girls and women in basketball, track, volleyball and softball, and made money by appearing in ads for TWA, American Express, Volkswagen, Drexel Burnham, Le Tigre Clothing and Foot Locker. After his basketball career, volleyball became Chamberlain's new passion: being a talented hobby volleyballer during his Lakers days, he became a board member of the newly founded International Volleyball Association in 1974, and then its president one year later. As a testament to his importance, the IVA All-Star game was televised only because Chamberlain also played in it: he rose to the challenge and was named the game's MVP. He played occasional matches for the IVA Seattle Smashers before the league folded in 1979. Chamberlain promoted the sport so effectively that he was named to the Volleyball Hall of Fame: he became one of the few athletes who were enshrined in different sports.
