when did the open era in tennis begin
History of tennis 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] (although it is acknowledged that this stereotype still exists).[8][9][10]
US Open (tennis) The US Open is held annually, starting on the last Monday in August, and lasting for two weeks into September, with the middle weekend coinciding with the Labor Day holiday. The main tournament consists of five event championships: men's and women's singles, men's and women's doubles, and mixed doubles, with additional tournaments for senior, junior, and wheelchair players. Since 1978, the tournament has been played on acrylic hard courts at the USTA Billie Jean King National Tennis Center in Flushing Meadows–Corona Park, Queens, New York City. The US Open is owned and organized by the United States Tennis Association (USTA), a not-for-profit organization. Net proceeds from ticket sales, sponsorships, and television deals are used to promote the development of tennis in the United States.
