Yet the men are paid more.
I'd look into these:
Greenawalt, Anne. Anne Greenawalt: Are Mens Sports Naturally More Exciting Than Womens Sports? Anne Greenawalt. N.p., 10 Dec. 2010. Web. 25 Apr. 2015.
Greer, J., Hardin, M. & Homan, C. (2009). Naturally less exciting? Visual production of mens and womens track and field coverage during the 2004 Olympics. Journal of Broadcasting & Electronic Media, 53(2), p. 173-189.
Hays, Graham. Why Men Dont Watch Womens Sports. Page 2. ESPN, 8 Mar. 2003. Web. 25 Apr. 2015.
Basically the problem is systemic. Even the coverage of women's sports is inferior. As if the coverage itself just doesn't care. So naturally the end product will be less interesting to fans.
I also personally have an issue with Women's volleyball. I don't watch it, because (my wife wouldn't ask me in the first place, but) I would be utterly self conscious trying to explain my interest in women's volleyball, given the attire. I understand some of the athletes choose to dress that way, and that's fine, but I'm like 'yeah, this is weird' watching it.
Womens and Mens soccer is basically the same, I enjoy following the USWNT because they kick ass. Which I suspect is at least partially due to under-interest/investment in women's teams worldwide, and where the USMNT can't do anything right and are severely outclassed at all times. US interest in women's soccer is enough to sustain a good team, where the rest of the world doesn't care much. US interest in men's soccer isn't enough to sustain a competitive mens team worldwide.
I enjoy women's volleyball and basketball, because the game is very different tactically.
