women's MMA

How does viewership of women's MMA compare with viewership of other professional women's sports? Anyone know?

I don't pay much attention to other sports. But I occasionally click through the ESPN site, and when I do I normally don't see anything about professional women's sports.

During the Olympics and women's world cup there are plenty of female stars. But in terms of everyday professional sports competitions (basketball, boxing, etc.) I don't see a lot about women's events.

Could it be that of all pro sports, MMA has the most gender equity in terms of viewership?

EDIT: I somehow forgot about tennis. There seems to be a number of female golfers who make bank, too.
