KEY BISCAYNE, Fla. — At the sun-soaked Sony Open held on this island east of Miami, the women have not been able to shine quite as brightly as the men — at least to those watching on television.

When Butch Buchholz, an architect of the professional game in the early Open era, founded the event in 1985, he packaged it as a “winter Wimbledon.” It remains one of the top tournaments outside the Grand Slam events to feature both men and women.

While the prestige, the fields (96 players in each draw) and the prize money have remained equal for men and women, the disparity in television coverage at this year’s tournament has been stark. By the end of the tournament, 71 men’s matches will have been produced for television and streaming, compared with 26 women’s matches.

From the quarterfinals on, all matches will be produced for television and streaming. But in the first four rounds, only 22 percent of the women’s matches were shown, compared with 74 percent of the men’s matches.
