Yes, I don't think PKB was right at all in that. The newspapers and media keep talking about it, to sell the story to non-tennis people (who don't pay much, nor do they watch much tennis on TV except for some GS final or something). As for the ones who pay for the tickets, season passes, and for the companies that sponsor the events, men's tennis has been way more attractive than women's. That is part of the reason why there is significantly more events and prize money on the men's tour than women's.
There are NO men's events under 400K prize money, but there are many many $175K and $200K women's events.
I just put som date into spreadsheets and checked the total prize money in the two tours. Taking out the 4 grand slams, Miami and Indian Wells where the men and women bring spectators together, we have 56 women's events and 61 men's events.
Prize money at the 61 men's events = $50.9 Million
Prize money at the 56 women's events = $26.7 Million
A case could be made that women only bring in 55% of what the men bring in.
I checked the one special event that could be a good comparison also -- The Canadian Open that switches back and forth between Toronto and Montreal in alternate years, either the men's or the women's event being at each city every year. Organized by the same TennisCanada people, who use their usual sponsors.
Men's prize money at the Canadian Open = $2.45M
Women's prize money at the Canadian Open = $1.34M
See that it is about 55% worth, using that data point too.
The women's tour now makes an argument that ATP forces top players to go to masters events while WTA doesn't. They conveniently forget that the prize money situation was exactly the same when ATP did not have mandatory masters'e events in the "super-9" time a few years back.
Basically the numbers do not back up the argument that the women's tour brings inmore money etc. Neither is it correct that women's event kept tennis afloat etc. That is stuff the media writes with no evidence, for NON_TENNIS people who are not serious, who don't pay, are not part of sponsorship equations, and are not interested in anything more than watching the "beauty" on display on the women's tour - or in hearing the TV news and in reading some newspaper reports if accompanied by a Sharapova, Serena or sania picture (hence the media feeds them that stuff). So, don't buy that hype in the press.
I could accept other arguments in favor of equal prize money, but economics is not one! .. Sorry, women are only worth 55% for the tennis fans
