Wrestling has always been considered more kid/family friendly (with the exception of ECW and CZW, and look how big they made it),
that has nothing to do with the statement, and it's wrong.
Actually, I would say you are very wrong.
To anyone who does not wrestling and does/or does not watch UFC, wrestling is viewed as something you grow out of when you are a kid.
to non-fans, yes, there is that perception. but how often does perception actually equate to reality? the majority of the people you see at shows are adults. there is a large adult audience for wrestling. yet, they have no product on television at current that caters to their interest.
as I said earlier, the linkage between wrestling and mma is very close. Dan Severn was one of the top UFC guys in the early 90's and held the NWA championship as well during that time, mixing both.
Heyman was ahead of the curve in promoting Taz as a UFC type wrestler and bringing in an actual fighter (Paul Varelans(sp?) to face him in ECW.
Mahon attempted the same with Shamrock and Severn later on, but didn't know how to promote them properly at that time as they were not heavy with talent that could properly work with them.
also, Shamrock actually trained for wrestling before going into UFC. he trained in florida with the Malenkos.
this is not even taking into account the more recent crossing over and similarities. they may not want to acknowledge it in their promotions and MMA fans may cry otherwise, but the two are actually very closely linked.
On top of that, the bulk of people that are into wrestling now, got into it as children.
Not that many people get into wrestling as adults.
this is true, it's also irrelevant to the point.
