This organization is aces with fans of women's tennis. The governing body for professional women's tennis, WTA Tour regulates the sport as a member of the International Tennis Federation and it sanctions 55 tennis events each year in more than 30 countries. Boasting more than 2,500 players from more than 95 different countries, the association markets the game and its players and generates revenue through merchandising, sponsorships, and selling broadcasting rights to its events. The WTA Tour was founded in 1973 when a number of top players, including Billie Jean King, decided to take the sport from an amateur level to professional.
Former WTA Tour president Stacey Allaster was promoted to chairman and CEO in 2009, replacing longtime chief Larry Scott who resigned to become commissioner of the Pac-10 college athletic conference. The change in leadership came as the women's tennis organization looks to renew its tour sponsorship deal Sony Ericsson. The handset maker inked a six-year, $88 million marketing deal with WTA Tour in 2005.
