Let’s say you launch a product in 2001. After a successful marketing campaign, a lot of people buy your product. Five years after, sales start dropping. Where is the problem?

It’s logical, goddamn it!

How many iPods you think people buy a year? 2? 3? One, just one! Maybe one every two years, but that’s kinda it!
Of course, what is logical for some people, is not for others.
