I believe that there isn't a requirement or isn't aimed at anyone in particular such as adults, children, etc, it's aimed at those who are willing to watch it and make the company money. Adults are the one's that earn money so people could say it's aimed at them however children can ask their parents for certain things e.g, merchandise, ordering a PPV, etc. It's a mixture really, no one's a target, just whoever is seen to draw the most money for the companies. It's all strictly business and it shall remain like that till the end of the world.
