I guess the question that needs to be answered is...
What is the trend in annual subscriptions for Inside Kung fu magazine?
If their subcription base is decreasing then you are all right on the money here.... If they are increasing their base, then what would you have them do?
Change the name to Inside MMA Magazine. If I'm interested in MMA and buy a magazine called Inside MMA, and then the content is geared towards Kung Fu, I might get a little miffed.
