Real answer for TS. WWE is massive in it's own weird way. Like if you ask a random person on the street about it chances are they will have no idea about what's going on. However there are some people that watch WrestleMania every year just because it's so over the top crazy and worth catching once a year or so.
Back in like 96-2004 it was HUGE and was very well known. People like Jay Leno appeared at WCW events and it wasn't considered as weird as it is today. For a brief period it was "cool" in pop culture, like comic book movies, video games, and zombies are now.
There's some crossover between them in terms of fans, but not a ton. WWE today is marketed more towards being a kid's product. However Vince is very into whatever is "cool" for the moment. He has brought in people like Shaq, Mike Tyson, Arnold, Ronda, and Floyd Mayweather for bits. Back in the day he brought in Mr.T and Lawrence Taylor. He tries to stay "cool" by finding what is currently popular. Whether or not it works is different story. They make big money though....
