#1.) Potential mainstream attention
There are few things that WWE seeks more than mainstream attention. The mainstream audience they had around The Attitude Era and even the Golden Era was on another level. Naturally, it decreased over the years. Bringing intergender wrestling into the fray may very wel be one of WWE’s solutions to bringing back mainstream audiences.
Wouldn’t it be crazy for someone who stopped watching years ago to find out that men and women compete against each other? It could create a lot of buzz for sure.
