See, I think this is the big elephant in the room. A lot of women are interested in sports, just not when women are playing. People want to see the best of the best, not a watered down version. The bigger the divide between men and women in a particular sport the more stark this is.
Alot of women are interested in sports, but the majority aren't and the ones that are usually are largely casual fans who probably like being part of the crowd and cheering for their local teams and join in the excitement and fun.
There are a number of men who are probably the same, but there are also plenty who follow teams closely and hangout at sites like HFboards and other places to talk about every player on their team, whether they're contributing enough to be worth what they're paid, how they can improve their team etc. I see far more men be this passionate about the teams they follow than I ever see women do so.
So yes many women like to watch sports, but even among those the majority are probably casual fans that can barely name anyone other than the stars on the team and probably don't care much beyond cheering when their team scores.
Edit: I was just watching that CTV show The Social where you have several women discussing entertainment and current events. They were just talking about how great it was for the Canadian women winning gold in hockey and of course it led to the next topic of why women's sports aren't supported more and how unfair it is and so on.
While watching this, I wondered how many of these 4 women who are so keen to see women's sports succeed, how many of them watched female sports regularly or attended any female sporting events live let alone sports in general? I'm betting probably all of them barely cared about sports at anything but the most casual level which is what I was saying before. Most women are probably like them when it comes to their interest in sports whether male or female. There's no way women's sports can succeed when most women are probably like the women on that show.
