In the year 2008, WWE's total revenue from corporate sponsorship was $7.4 million. Since then, the company has been focused on a more PG product and promised sponsors that the days of racy TV were over.

This year, WWE's total revenue from corporate sponsorship is expected to be $20 million.

Obviously, this is a MAJOR part of the reason that WWE went PG. It's all about the money!
