Maybe because they would like a demographic younger than 80. There is a great scene from the movie "Parental Guidance" that explains this perfectly. Billy Crystal is an aging minor league baseball announcer that gets fired for being to old school.
Well, if these sports teams want a demographic younger than 80, what are we saying? We’re saying they need to blast all of our eardrums with loud rock music?? The younger people won’t go to a baseball game just for the appreciation of baseball; they need a constant soundtrack?? IN many stadiums, a soundtrack which is so loud you can’t talk to the people next to you?
How does this make sense, in that, if you gain some youngsters who won’t go to a game otherwise, but you lose hard core fans such as myself???
