Tennis

Tennis is a versatile racket sport played globally by people of all ages and abilities.

It can be played as singles, which is a match between two individuals. It can also be played as doubles, featuring two teams of two players each. Players use a racket strung with cord to strike a hollow rubber ball. This ball is covered in felt and must be hit over a net. The primary objective is to maneuver the ball so an opponent cannot make a valid return. If a player fails to return the ball correctly, the opponent scores a point. This sport is inclusive and can be played by anyone, including wheelchair users.

The mechanics of a match involve strategic movement and precise striking. Players must hit the ball into the opponent's court area to maintain play. Modern professional matches often utilize electronic review technology called Hawk-Eye. This system allows players to challenge a line call during a point. This technology helps ensure accuracy in high-stakes competition. While the core gameplay remains steady, rules have evolved over time. For example, prior to 1961, a server was required to keep one foot on the ground. Additionally, the tiebreak was adopted in the 1970s to resolve close sets.

The history of tennis traces back to 12th-century northern France. Early players used the palm of their hands to strike a ball. This version was known as jeu de paume, or "game of the palm."

King Louis X of France was a dedicated player of this game. He is historically significant as the first named tennis player. Louis X even commissioned indoor, enclosed courts in Paris around the end of the 13th century. The name "tennis" likely derives from the French interjection "tenez." This word translates to "hold!", "receive!", or "take!" and was used by servers to alert their opponents.

Modern lawn tennis emerged in Birmingham, England, during the mid-19th century. Between 1859 and 1865, Harry Gem and Augurio Perera developed a game on a croquet lawn. Their version combined elements of racquets and the Basque game known as pelota. In 1872, they founded the world's first tennis club in Leamington Spa. Later, in 1873, Walter Clopton Wingfield patented a game he called sphairistikè. This Greek term means "ball-playing." Wingfield is credited with popularizing the sport by marketing boxed sets containing nets, rackets, and rules. He sent thousands of these sets across the world in 1874.

The sport expanded rapidly to the United States in 1874. Mary Ewing Outerbridge brought a sphairistikè set to New York after visiting Bermuda. The first American National championship took place in September 1880 at Staten Island. An Englishman named O.E. Woodhouse won the inaugural singles title. To standardize varying regional rules, the United States National Lawn Tennis Association was formed in 1881. This organization eventually became the United States Tennis Association. The US Open, originally the US National Men's Singles Championship, began in 1881 at Newport, Rhode Island.

Today, the highest level of competition is defined by the four Grand Slam tournaments. These are often called the "majors," a term borrowed from the game of bridge. The Australian Open is played on hardcourts. The French Open is played on red clay courts. Wimbledon is famous for its grass courts. The US Open is also played on hardcourts. These four events represent the pinnacle of competitive tennis. Tennis is also a consistent part of the Summer Olympic Games, having returned as a full-medal sport in 1988.

The sport underwent a massive shift during the 1968 Open Era. Before this, professional players were not allowed to compete in major amateur tournaments. Commercial pressures and rumors of illegal payments led to the abandonment of this distinction. Now, all players can compete in all tournaments, allowing professionals to earn a living. This change, combined with television rights, helped tennis spread its popularity worldwide. The sport has moved beyond its middle-class English-speaking stereotype to become a truly global phenomenon.
