More women play both doubles and singles because a good WTA doubles player would most of the time be a very competitive single player, which isn't the case in the men circuit.
If the Bryans, Lindsted, Tecau, Zimonic, etc. would be competitive enough in singles, they would be playing both (like Kubot f.e.) and it would be the same for both genders.
About the "boxing case" "smart" reply - do you think spectators going to watch WTA matches expect more than what they get?
So what is your (stupid and aggressive) post about exactly?
Federer and Nadal are huge global stars and the ATP is more popular overall than the WTA
- that's the main point - IMO it isn't and you couldn't know, just as i couldn't be sure.
As elaborated earlier, i will go again to clarify my point - tennis fans, who know and like tennis are maximum 2%-5% of the world.
Even if we assume that they all are fans of ATP only, it is still up to 300mil.
A Li Na - Serena Williams final in any GS could make 200mil in China only. That's 15% of the population. I can't be sure, true, but most of you guys don't know what means the pride of the sports achievements in the communist countries. I know, i'm old enough to remember.
Anyways, we're just speculating and the main argument for most is - ATP is more popular. Yes, for MTF users...
