#2 The legitimacy factor
It's amazing what a change of network can do for a television show. Not only did it take SmackDown from a humdrum secondary show to a Friday night thriller, but it also unleashed energy in the Blue brand that hasn't been seen in quite some time. Moving to FOX was the refresh WWE needed and it's coming with quite a few benefits as well.
If nothing else, the move has given Friday Night SmackDown a level of legitimacy that the show would have been unlikely to gain otherwise. In fact, between Cain Velasquez appearing on the first episode to confront Brock Lesnar and the network promoting the show during NFL games throughout the week, it's safe to say that more eyes are on the Blue brand than ever before.
WWE has even gone so far as to have draft panels, a pre-game show, and more of a focus on the sports-oriented nature of professional wrestling. Of course, there's a promo or a run in here and there when the time calls for it. It wouldn't be professional wrestling otherwise, but SmackDown's bread and butter is now the legitimacy factor.
