Simply put, if there's an audience for it, and it can generate ratings and advertisers are interested in supporting this network, it'll survive. If they find there isn't enough audience/ratings/advertiser support, it won't.
While I don't mean any disrespect, they may have some difficulty. While some sports like women's 2 on 2 volleyball can be interesting, women's sports in general simply don't attract the same audience as men. The women's soccer team made a huge deal about the fact that they weren't paid as much as the members of the men's soccer team, also making the case that the men didn't have a great record, while the women were winning championships. They demanded (and eventually won) equal pay. That said, even though they play with just as much heart as the men, and they indeed have a better winning record, at the same time, the audience and fan interest simply isn't the same, and thus, neither is the revenue generated. Again, I'm not intending that in a disrespectful way, but it is the apparent reality of the situation.
