Atlanta is a financially profitable revenue for Professional wrestling. It's been that way since WCW had it's base of operations there. Ticket sales are and Merchandise sales are always where the majority of the company's money will be greatly earned. Atlanta, much like other major cities, never disappoints in sales no matter how the crowd sounds on tv.
Basically Big Arenas + Large crowds = WWE return trip each time.
If this is accurate, (I am no judge of the information on revenue nor do I care to do any of my own research) then this is the most important post in this thread.
