The History of Tennis: From Real Tennis to Wimbledon and the Open Era

The Game That Began Indoors

Lawn tennis was invented twice — once in the twelfth century, and once in 1874. The original game, jeu de paume (palm game), was played indoors in French monastery courtyards as early as the 1100s, using the palm of the hand to hit a ball across a rope or net strung between walls. By the sixteenth century, it had evolved into what the English called real tennis (or royal tennis) — played on an enclosed, asymmetric court with sloping roofs, galleries, and complex rules governing where balls could land. Henry VIII was a passionate real tennis player; Hampton Court Palace still has a functioning real tennis court. Approximately 45 real tennis courts survive in the world today, hosting a small but dedicated community of players.

The outdoor version — lawn tennis — was patented by Major Walter Clopton Wingfield on February 23, 1874, under the somewhat extravagant name Sphairistikè (Greek for "skill in playing with a ball"). Wingfield's original court was hourglass-shaped, narrowing at the net. His rules were quickly adapted and improved by the Marylebone Cricket Club and then standardized by the All England Lawn Tennis and Croquet Club, which held the first Wimbledon Championship in July 1877. Spencer Gore, a rackets player, won the 22-man field. Approximately 200 spectators paid one shilling each to watch.

From Davis Cup to Grand Slams: Building the Structure

International tennis competition began with the Davis Cup, established in 1900 as a challenge between the United States and Great Britain (then simply "the British Isles"). Dwight Davis, a 21-year-old Harvard student and US doubles champion, donated the silver bowl that bears his name. The competition expanded over decades into the largest annual international team competition in any sport — 135 nations participated as of 2023.

The four Grand Slams — Wimbledon (1877), the US Open (1881 as the US National Championship), the French Open (1891 as the French Championships), and the Australian Open (1905) — developed independently before the term "Grand Slam" was coined. American Don Budge became the first player to win all four major titles in a single calendar year in 1938, inspiring journalist Allison Danzig to borrow the bridge term for winning all tricks. Budge himself preferred the phrase; the term has defined tennis excellence ever since.

The Open Era: When Professionals Were Finally Allowed

For most of tennis's history, the most important tournaments — including all four Grand Slams — were restricted to amateurs. Professional tennis players, those who accepted prize money or appearance fees, were banned from Wimbledon, Roland Garros, Flushing Meadows, and Melbourne. This created an absurd situation: the best players in the world, who had turned professional to earn a living from the sport, were excluded from the sport's most prestigious events.

The prohibition ended on April 22, 1968, when the International Lawn Tennis Federation voted to open Grand Slam tournaments to all players regardless of professional status — the beginning of the Open Era. The 1968 Wimbledon was the first open Grand Slam; Rod Laver and Billie Jean King won the singles titles. Prize money totaled £26,150. The transformation was immediate and irreversible: the world's best players were finally in the same tournament.

The Equal Prize Money Timeline

Women's tennis fought a separate, extended battle for equal prize money — a battle that took four decades to win even in principle.

Billie Jean King's role in the equal pay movement extends beyond advocacy. Her 1973 "Battle of the Sexes" match against 55-year-old Bobby Riggs — watched by an estimated 90 million television viewers worldwide and won by King 6–4, 6–3, 6–3 — was a cultural event that shaped public perception of women's athletics far beyond tennis.

Technology's Transformation of the Game

Three technological developments fundamentally changed how tennis is played.

The tiebreak: Jimmy Van Alen, a Newport millionaire and amateur tennis patron, invented the tiebreak in 1965 as the VASSS (Van Alen Streamlined Scoring System), designed to shorten matches and make tennis more television-friendly. The US Open adopted a tiebreak at 6–6 in all sets in 1970. Wimbledon introduced a tiebreak at 6–6 in all sets except the fifth (later changed to a 12-point tiebreak at 12–12 in the fifth) in 1971. Before the tiebreak, sets could theoretically continue indefinitely; the 2010 Wimbledon match between John Isner and Nicolas Mahut ended 70–68 in the fifth set — the longest match in Grand Slam history and a demonstration of why the tiebreak was invented.

The spaghetti racket: In 1977, a German amateur named Werner Fischer introduced a racket strung with a double layer of crossing strings that produced extreme spin by grabbing and releasing the ball unpredictably. Players using it were beating top professionals. The International Tennis Federation banned it within months — one of sport's fastest regulatory responses to a technological innovation.

Graphite and composite rackets: Until the early 1980s, wooden rackets were universal. The transition to graphite composite frames — lighter, stiffer, and allowing larger hitting surfaces — enabled dramatically more powerful groundstrokes and fundamentally changed the balance between serve-and-volley and baseline play. The transformation happened within five years. By 1985, wooden rackets were museum pieces.

Hawkeye and the Challenge System

Electronic line-calling was introduced at the 2006 US Open through the Hawkeye challenge system, allowing players to challenge up to three incorrect line calls per set. Hawkeye uses a network of high-speed cameras and triangulation algorithms to predict where the ball landed to within 2.6 millimeters accuracy. The challenge system transformed line-call controversies from he-said-she-said disputes into data-resolved certainties — and created an unexpected element of drama as players and crowds awaited the slow-motion replay.

The 2020 COVID pandemic accelerated the transition: tournaments moved to fully electronic line calling without human line judges, reducing the cost of officiating and eliminating calling errors simultaneously. Wimbledon, the most tradition-bound tournament in the sport, finally removed line judges entirely in 2025. The sport that took 140 years to equalize prize money moved to full electronic officiating within a decade of the technology's maturation.

The Big Server Era and Court Speed Controversy

The Open Era's final decades have been dominated by a technological-physical paradox. As racket technology and physical training produced increasingly powerful serves — some exceeding 150 mph — the balance between serving and returning has shifted dramatically toward servers on faster court surfaces. This has generated sustained controversy about whether court surfaces should be slowed to produce longer rallies and more entertaining play.

Wimbledon's grass was demonstrably faster in the 1990s than today; the club has progressively introduced harder-wearing grass varieties that produce a higher bounce and slower pace. The French Open's clay has been resisted as a traditional haven for baseliners. The general trend across all surfaces has been toward slower courts that favor rally play — a deliberate competitive and commercial choice prioritizing entertainment over the serve's natural dominance on fast surfaces.
