Tennis is a racquet sport played between two or four players. Players use racquets to hit a hollow rubber ball over a net and into the opponent's court. The goal is to win points by hitting shots that the opponent cannot return. Tennis originated in England in the late 19th century and is now an Olympic sport played worldwide by millions of recreational and professional players. Major professional tournaments include the Australian Open, French Open, Wimbledon, and US Open played on different court surfaces.
