Women's Tennis Association

WTA stands for Women's Tennis Association, and is also known as the WTA Tour, and is to women's tennis what the ATP is to men's tennis. In 2005 the WTA changed its name into The Sony Ericsson WTA Tour.

The Women's Tennis Association was begun in Houston, Texas when the inaugural Virginia Slims event was won on 23 September 1970. Billie Jean King was a major figure in the early days of the WTA.
