#4. PG rating and targetted audience
WWE, since 2008, decided to change their rating to PG. There was an instant difference in the programming and instant criticism as well, with fans feeling that WWE hampered their product and made far too many restrictions.
However, WWE turned out to be right about going PG and fans later realized that having PG-14 doesn't guarantee a good product. More than anything, the PG Era has seen WWE's sponsorship revenue shoot up and they have all sorts of tie-ups with big companies for various causes.
The fact of the matter is that the PG Era was the right direction to go with, but that may have resulted in WWE limiting their promos and the level in which they can improvise. Because they're so keen on targetting the children and family audience, they probably feel it's best to be restrictive on the promos that they cut.
