The Davis Cup, an annual competition between men's national teams, dates to 1900.[2] The analogous competition for women's national teams, the Fed Cup, was founded as the Federation Cup in 1963 to celebrate the 50th anniversary of the founding of the ITF also known as International Tennis Federation.[3]
In 1926, promoter C.C. Pyle established the first professional tennis tour with a group of American and French tennis players playing exhibition matches to paying audiences.[4][5] The most notable of these early professionals were the American Vinnie Richards and the Frenchwoman Suzanne Lenglen.[4][6] Once a player turned pro he or she could not compete in the major (amateur) tournaments.[4]
In 1968, commercial pressures and rumors of some amateurs taking money under the table led to the abandonment of this distinction, inaugurating the open era, in which all players could compete in all tournaments, and top players were able to make their living from tennis.[7] With the beginning of the open era, the establishment of an international professional tennis circuit, and revenues from the sale of television rights, tennis's popularity has spread worldwide, and the sport has shed its upper/middle-class English-speaking image[8]
