Stumpman, a customer is somebody who pays for a good or a service. Not the case here.
I recently read an article that made me laugh... Basically, about one teenager out of two massively uses firesharing to download huge amounts of music. According to the survey, stores such as iTunes make no difference. Teens responded: Why pay for something I can get for free?
On the other hand, and here is the irony, those same teens will gladly and proudly pay 2 or 3 dollars for a 30 second RING TONE for their cell phone... and yet they won't pay 1 dollar for a complete 3 minute song. Funny, isn't it? Busted me up when I read that.
Anyway, online stores such as Apple's, much appeal to the adult population but very little to the teens - which were typically the #1 customers for CD's and records.
Movies are a different matter though. Teens were never a big client base for the purchase of movies. On the other hand, it might be hurting the video rental industry... or maybe not, dunno. There seems to be as many people in the video store now than there always was.
