Professional tennis has changed from a sport split between wealthy amateurs and traveling professionals into a global tour followed by millions of fans. The biggest turning point came in 1968, when top professionals were allowed to compete alongside amateurs in the major championships. That shift created the modern era of tennis.
Understanding professional tennis history also means looking beyond famous champions. Changes to the tours, equipment, prize money, and playing styles have all shaped the game. Here are the key moments that explain how tennis became the sport we watch today.
How Modern Tennis Began
Modern lawn tennis took shape in Britain in the 1870s. Major Walter Clopton Wingfield helped popularize a version of the game in 1873, and Wimbledon held its first championship in 1877. The sport grew quickly, with national championships appearing in the United States in 1881, France in 1891, and Australia in 1905.
Those early championships were not yet open to the world’s best players. For much of tennis history, a sharp line separated amateurs from professionals. Players who accepted money for competing could be barred from the major events. As a result, leading professionals often played exhibitions and tours rather than the championships that attracted the widest attention.
The Amateur Era and the Open Era
The amateur-professional divide became harder to defend as tennis grew. Top professionals had strong skills and large audiences, but they could not compete for the sport’s most important titles. In April 1968, tennis entered the Open Era: tournaments could admit both amateurs and professionals.
The 1968 French Championships, now known as Roland-Garros, became the first Grand Slam tournament of the Open Era. Wimbledon and the other majors followed that year. The change brought the best players together and gave them a clearer path to earn money from the sport.
Rod Laver showed how much was at stake in this new era. He won the calendar-year Grand Slam—the Australian Open, French Open, Wimbledon, and US Open—in 1969, becoming the first man to complete it in the Open Era. He had also achieved the feat in 1962, before the divide ended. Margaret Court completed a calendar Grand Slam in 1970, a remarkable achievement across the changing landscape of women’s tennis.
Professional Tours Take Shape
As tournaments multiplied, players needed more organized schedules and representation. The Association of Tennis Professionals (ATP) was founded in 1972. The Women’s Tennis Association (WTA) followed in 1973, led by players including Billie Jean King. The groups helped give players a stronger voice in decisions about competition, working conditions, and prize money.
King’s impact reached beyond the tour structure. In 1973, the US Open became the first Grand Slam to award equal prize money to men and women. That step did not settle the wider pay debate, but it set an important standard. Other majors later adopted equal prize money, with the French Open doing so in 2006 and Wimbledon in 2007.
Rankings also made the sport easier to follow. The first official ATP rankings appeared in 1973, helping fans compare players across tournaments. The WTA rankings began in 1975. Today, rankings shape seedings, qualification, and the race to end each season among the top players.
Champions Who Changed the Game
Every era has had players who changed what fans thought was possible. In the 1970s, Billie Jean King combined attacking tennis with leadership off the court. Her 1973 “Battle of the Sexes” match against Bobby Riggs drew huge attention, while her work helped build a more unified women’s tour. On the men’s side, Björn Borg’s cool control and success on both clay and grass made him one of the defining champions of his time.
The 1980s and 1990s brought new power and athleticism. Martina Navratilova dominated with a serve-and-volley game built on fitness and precise net play. Steffi Graf paired speed with a powerful forehand and won the 1988 Golden Slam: all four majors and Olympic gold in the same year. Pete Sampras became known for his attacking serve and Wimbledon success, while Andre Agassi showed how a strong return and groundstrokes could take time away from opponents.
In the 2000s and beyond, Roger Federer, Rafael Nadal, and Novak Djokovic set a new standard for sustained success. Federer’s movement and shot-making, Nadal’s heavy topspin and court coverage, and Djokovic’s flexible defense and return game created a long-running rivalry. Serena Williams became one of the most successful players of the Open Era, combining a powerful serve with aggressive court positioning. Their careers helped make the sport more global and raised expectations for consistency at the top.
| Milestone | Why it mattered |

| Open Era begins in 1968 | Allowed professionals to compete in major championships. |
| ATP founded in 1972; WTA in 1973 | Gave players organized tour representation. |
| US Open awards equal prize money in 1973 | Set an early standard for equal pay at a major. |
| Official ATP rankings start in 1973 | Created a consistent way to track men’s results across tournaments. |
How Equipment and Tactics Evolved
Professional tennis history is also a story of changing rackets and court conditions. Early players used wooden rackets with small heads. Metal frames arrived later, and lighter graphite-composite rackets became common in the 1980s. Larger racket heads and stronger strings made it easier to hit with pace and spin, though they did not make technique irrelevant. Players still need timing, footwork, and good decisions under pressure.
These changes affected tactics. Wooden-racket tennis rewarded precise placement and frequent net attacks. Modern equipment helps players hit forceful shots from behind the baseline, so long rallies and heavy topspin are now common. Still, serve-and-volley tennis can work on faster courts, and variety—such as a sliced backhand, drop shot, or well-timed approach—remains useful against a player who prefers to stay back.
Courts and schedules have shifted, too. The Australian Open moved to hard courts in 1988, and the US Open has used hard courts since 1978. Wimbledon remains on grass, while Roland-Garros is played on clay. Each surface rewards different skills: grass tends to favor quick reactions and an effective serve, while clay gives players more time to defend and build points.
