History of the WTA World Tour

The early years: women’s tennis before the WTA

Women’s tennis developed through clubs, national championships and international competitions long before the modern WTA Tour existed. The sport was included in the Olympic Games in 1900, when women’s singles and mixed doubles were contested in Paris. During the early twentieth century, women’s tennis gained prominence through major championships, particularly Wimbledon, the US Championships, the French Championships and the Australian Championships, which would later become the four Grand Slam tournaments.

By the 1960s, leading women’s players were attracting substantial audiences, but their professional opportunities and financial rewards remained significantly behind those available to men. Tennis was undergoing a broader transformation following the beginning of the Open Era in 1968, when Grand Slam tournaments opened their doors to both amateur and professional players. This change allowed the sport’s leading competitors to earn money at major championships, but it did not immediately resolve inequalities in prize money or the fragmented organisation of women’s tennis.

1970: the Original Nine and the birth of a movement

A defining moment arrived in September 1970, when nine leading women players signed professional contracts with promoter Gladys Heldman to compete in a new women’s tournament at the Houston Racquet Club in Texas. The players became known as the Original Nine: Billie Jean King, Rosie Casals, Nancy Richey, Kerry Melville Reid, Peaches Bartkowicz, Kristy Pigeon, Valerie Ziegenfuss, Julie Heldman and Judy Dalton.

The tournament offered $7,500 in total prize money and was supported by Virginia Slims, a cigarette brand that became a major sponsor of women’s professional tennis during the following decade. The players accepted the risk of challenging the existing system because they wanted greater control over their careers and a fairer share of the sport’s commercial success.

The significance of the Original Nine went far beyond one tournament. Their decision helped establish the principle that women’s tennis players could organise collectively to improve their working conditions. Their actions laid the foundations for a more unified professional circuit and became a landmark in the history of women’s sport.

1973: the Women’s Tennis Association is founded

On 21 June 1973, Billie Jean King founded the Women’s Tennis Association (WTA), bringing women’s professional players together under a single organisation. The association aimed to give players a stronger collective voice, improve tournament organisation and increase commercial opportunities for the women’s game.

Later that year, King won the US Open singles title, becoming a leading symbol of the fight for equality in tennis. The 1973 US Open was also historic because its men’s and women’s singles champions received equal prize money. The decision made the tournament the first of the four Grand Slams to award equal prize money in those singles competitions.

Another defining event took place on 20 September 1973, when King defeated Bobby Riggs in the nationally televised Battle of the Sexes match in Houston. Riggs was a former men’s world number one who had publicly challenged leading women players. King’s victory attracted enormous attention and became a landmark cultural moment in debates about women’s sporting ability and equality. Although it was an exhibition rather than a WTA Tour tournament, it helped bring women’s tennis to a much wider audience.

The 1970s and 1980s: growth, sponsorship and global stars

During the 1970s, the women’s professional circuit expanded, supported by increased television exposure and commercial sponsorship. The Virginia Slims circuit became a major part of the tour’s development, helping establish a more consistent schedule of professional tournaments. The WTA’s unified structure made it easier for players to coordinate their interests and for sponsors to invest in women’s tennis as a distinct sporting product.

The sport also enjoyed a golden period of rivalries. Chris Evert became one of the defining players of the era through her remarkable consistency, particularly on clay courts. Martina Navratilova emerged as another dominant champion, combining attacking net play, athleticism and exceptional fitness. Their rivalry, which began in the early 1970s and continued for many years, produced some of the most important matches in women’s tennis history.

Evert and Navratilova met 80 times in official singles competition, with Navratilova winning 43 of those encounters and Evert winning 37. Their repeated battles helped demonstrate the competitive depth and commercial appeal of women’s tennis. They also illustrated the variety of approaches that could succeed at the highest level, from Evert’s outstanding baseline consistency to Navratilova’s aggressive all-court game.

The 1990s: a more commercial and internationally recognised tour

The 1990s saw women’s professional tennis become increasingly global, with players emerging from a wider range of countries and commercial interest continuing to grow. Steffi Graf dominated much of the late 1980s and 1990s, winning 22 Grand Slam singles titles during her career. In 1988, she achieved the Golden Slam by winning all four Grand Slam singles titles and the Olympic gold medal in the same calendar year, a feat unmatched in singles tennis.

Monica Seles also became a dominant force, winning eight Grand Slam singles titles before her nineteenth birthday. Her aggressive two-handed groundstrokes and distinctive on-court style changed the way many players approached baseline tennis. In April 1993, Seles was stabbed by a spectator during a match in Hamburg, Germany. The attack interrupted her career for more than two years and remains one of the most disturbing incidents in professional tennis history.

As television coverage expanded, tournaments attracted larger audiences and sponsors increasingly recognised the commercial value of leading women’s players. The WTA continued to develop its tournament structure, providing a clearer framework for professional competition and helping the sport reach fans in more countries.

2000–2009: the Williams sisters and a new era of power

The early twenty-first century was shaped in large part by Venus and Serena Williams. The sisters brought exceptional athleticism, powerful serving and aggressive baseline play to the top of the women’s game. Venus won her first Grand Slam singles title at Wimbledon in 2000, while Serena captured her first major singles championship at the US Open in 1999.

Serena went on to become one of the greatest players in tennis history, ultimately winning 23 Grand Slam singles titles in the Open Era. Venus won seven Grand Slam singles titles and became a leading advocate for equal prize money at Wimbledon. Their success contributed to major changes in the sport’s visibility and helped inspire a new generation of players.

In 2007, Wimbledon announced that it would award equal prize money to men and women in its singles and doubles competitions, ending a longstanding disparity at the tournament. The French Open had already adopted equal prize money in 2006. These developments followed years of campaigning and reflected the wider progress made by women’s professional tennis since the Original Nine’s stand in 1970.

2009: the modern Premier structure

In 2009, the WTA introduced a revised tournament structure that included Premier Mandatory, Premier 5, Premier and International events, alongside the Grand Slams and other competitions. The new system aimed to make the calendar easier to understand, strengthen the tour’s identity and create clearer distinctions between tournament categories.

The season-ending championships also became an important focal point for the leading players. Known through various sponsorship arrangements as the WTA Championships and later the WTA Finals, the event offered a prestigious opportunity for the best performers of the season to compete for a major year-end title.

2010–2019: global expansion and record-breaking champions

The 2010s featured remarkable champions and an increasingly international tour. Serena Williams continued to collect major titles, finishing her career with 23 Grand Slam singles championships in the Open Era. Her combination of power, serving and competitive determination set a benchmark for generations of players.

Other stars also shaped the decade. Maria Sharapova won five Grand Slam singles titles and completed a career Grand Slam by winning all four majors at least once. Victoria Azarenka, Kim Clijsters, Justine Henin and Li Na added to the depth of the women’s game, while Li’s 2011 French Open victory made her the first player from an Asian country to win a Grand Slam singles title.

In 2015, the WTA introduced the Road to Singapore campaign for its season-ending championships, emphasising the race to qualify for the WTA Finals. The event was held in Singapore from 2014 to 2018, illustrating the tour’s efforts to strengthen its presence in Asian markets and reach new audiences.

Off the court, the WTA continued to address issues affecting player welfare, tournament conditions and equality. The tour’s international reach expanded as professional events developed in new markets, while its digital platforms helped fans follow matches, rankings and player stories throughout the season.

2020–2021: disruption and change

The COVID-19 pandemic dramatically disrupted professional tennis in 2020. The WTA suspended its tour for several months, and Wimbledon was cancelled for the first time since the Second World War. When competition resumed, tournaments operated under changing health protocols, travel restrictions and spectator limitations.

The disruption demonstrated the complexity of running a worldwide professional tennis circuit. Players had to adjust to unfamiliar schedules, quarantine requirements and restrictions on travel, while tournament organisers faced considerable financial and logistical challenges. Despite these obstacles, the tour gradually returned to a more regular calendar during 2021.

2022–2023: a new brand and renewed focus on the players

In December 2021, the WTA announced that it would suspend its tournaments in China and Hong Kong in response to concerns about Chinese player Peng Shuai, whose safety and freedom to speak publicly had become an international issue following allegations she made against a former Chinese government official. The decision affected the tour’s calendar and commercial relationships, highlighting the difficult choices sports organisations face when player welfare intersects with politics and business.

In 2022, the WTA introduced a new visual identity and renewed emphasis on the WTA brand. The tour continued to promote women’s professional tennis globally, with increased attention to player visibility, commercial partnerships and the development of younger competitors.

In 2023, the WTA Finals returned to Mexico, with Cancún hosting the season-ending event. The tournament also highlighted the challenges of staging elite tennis events, including court conditions, weather and preparation time. Such issues remain important as the tour seeks to balance global expansion with the consistent playing conditions required by the world’s best athletes.

2024–2025: renewed investment and a changing competitive landscape

The 2024 season saw Aryna Sabalenka win the Australian Open and US Open women’s singles titles, while Iga Świątek continued to demonstrate her dominance on clay by winning the French Open. These results reflected the strength of a new generation of champions and the depth of competition at the top of the WTA rankings.

In 2024, the WTA Finals were held in Riyadh, Saudi Arabia, as part of a multi-year arrangement. The move marked a significant development in the tour’s commercial and geographical expansion and prompted wider discussion about investment in women’s sport, human rights and the responsibilities of international sporting organisations.

In 2025, the WTA continued its global tournament programme and the development of its commercial partnerships. The tour’s competitive landscape remained dynamic, with leading players competing for Grand Slam titles, ranking points and qualification for the season-ending WTA Finals. The modern WTA World Tour is the product of more than five decades of organisational growth, sporting excellence and campaigns for greater equality.

The legacy and future of the WTA World Tour

From the nine players who challenged the existing system in 1970 to today’s global professional circuit, the history of the WTA World Tour is a story of ambition, resilience and transformation. The organisation has helped establish women’s tennis as a major international sport, providing a platform for generations of champions and expanding opportunities for female athletes around the world.

The tour continues to evolve through changes in tournament formats, sponsorship, broadcasting, player development and global expansion. New stars emerge each season, established champions seek to extend their legacies, and fans follow the changing rankings with enormous interest. While the sport’s commercial environment and international schedule will continue to develop, its essential appeal remains the same: exceptional athletes competing under pressure, with every match offering the possibility of something extraordinary.

For anyone interested in women’s tennis, understanding the history of the WTA adds meaning to the modern game. Today’s players compete on a stage built by pioneers who fought for recognition and fairer opportunities. The result is a tour that combines sporting excellence with a lasting legacy of progress, making the WTA World Tour one of the most compelling competitions in international tennis.
