Who is the most famous athlete in the world? Ben Alamar, ESPN’s director of sports analytics, devised a formula that combines salary, prize money and endorsements with social media following and Google search popularity to create the ESPN World Fame 100 rankings.

The WTA’s brightest stars dominated the list: of the 8 women highlighted by ESPN, half are WTA players. Maria Sharapova (No.18), Serena Williams (No.25), Sania Mirza (No.41) and Venus Williams (No.74) were named as the most famous female athletes.

At No.18 on the list, Sharapova is the most famous female athlete in the world and her combined 17.6 million fans on social media can agree. From winning her first Grand Slam title at Wimbledon at the age of 17 to debuting her confectionary lines, the Russian’s broad popularity has cemented her position at the top.

Two “Serena Slams” 13 years apart speak to the longevity of Serena’s career, during which she’s amassed 70 titles and claims a combined 10.4 million social fans. Her off court activities – including a couple of viral cameos – keep her firmly in the pop culture spotlight as well. At No.25 she is the third most famous female athlete on the list.

A pair of trailblazers round out the ESPN World Fame 100 list: Sania Mirza and Venus Williams. Mirza galvanized an entire subcontinent when she became the first Indian woman to win a Grand Slam last year at Wimbledon, and the world’s No.1 doubles player continues to break barriers for women. Similarly, Venus made history when she became the first African-American player ever – male or female – to hold the No.1 ranking in tennis. Her 49 career titles are only eclipsed by her continuing contributions to equality in the game, and as a result she remains one of the most famous athletes in the world.
