BENGALURU, Sept 2 (Reuters) - The end of Serena Williams' glittering tennis career will have little to no impact on the American's brand value and her earnings from endorsements could even surge post-retirement, industry experts told Reuters.
Williams appeared to suggest last month that she would end her playing career at the U.S. Open, although she was a bit more vague about her intentions after her rousing first-round victory at Flushing Meadows in front of a celebrity-packed crowd.
Her third round loss to Australian Ajla Tomljanovic on Friday night, however, was likely her final Grand Slam match in a sport Williams has dominated for over two decades. read more
Sportswear giant Nike (NKE.N) has said it will continue to partner with Williams, who turns 41 later this month, after her retirement. Other major sponsors are likely to follow suit.
"While Serena's on-court visibility will fade ... I don't see any drop in her brand value," said Bob Dorfman, sports marketing analyst at San Francisco's Pinnacle Advertising.
"More than a tennis superstar, she's a legitimate icon," Dorfman said. "The highest-earning female athlete of all time will surely remain a high-powered brand, even after putting down her racquet."
The only way Serena's brand value will fade is if she decides to stay out of the spotlight, said Lisa Delpy Neirotti, director of sports management programs at George Washington University.
"But if she becomes a voice of some cause, if she stays relevant and in front of her fan base, then her value goes up," Neirotti added.
"She's been such a powerful player on and off the court ... I think she'll be relevant in social causes."
While several elite male athletes have forged successful post-playing career brands, Williams' accomplishments, including 23 Grand Slam singles titles, position her well ahead of other female athletes in terms of appeal to major sponsors.
"As no other active female player is close to her level of accomplishment, everyone coming up in women's tennis will continue to be compared with Serena for a long time to come," said Phil de Picciotto, founder and president of sports agency Octagon.

Few women athletes have had lasting appeal to sponsors after retiring. But Williams, who has earned $35.1 million this year to edge out former men's world No. 1 Rafa Nadal ($31.4 million) and Novak Djokovic ($27.1 million), should be an exception.
In June, she was named in the Forbes list of America's richest self-made women, with an estimated net worth of $260 million. Her one-time tennis rival, Maria Sharapova, was the only other athlete on the list.
"An athlete's cache can last well beyond their retirement, especially if they have GOAT (Greatest of All Time) status like Serena has," said Victor Matheson, sports economist at College of the Holy Cross in Massachusetts.
With Williams saying she will focus on her family post-retirement, endorsement deals coming her way may also change, said Iliya Rybchin, partner at marketing consulting firm Elixirr Consulting.
"Serena's one of those rare players who transcended the sport. Her value to brands is much more than just 'Serena the tennis player'," Rybchin added.
"When brands like Wilson, Nike and others first approached her, it was all about getting a high-performing, exceptional tennis player.
"Now ... the characteristics that are valuable to them are different, because they look at the demographics she's speaking to and the young players that might be inspired by her," Rybchin said. "For most brands, that story still works, whether or not she's on the court."
Williams' career prize money of $94.6 million is dwarfed by her endorsement income - estimated to be about $340 million - and the ball is in her court as she looks ahead to life without the demands of being an elite athlete.
"She'll now have the full time and opportunity to expand her sponsor base," said Larry Mann, partner at sports marketing and media agency rEvolution.
