The folks that have been in the book and music industry THINK they are in the business of selling a physical item. Be it a book, a record, or a CD. The problem they have to get over is that it’s not the medium it’s the content that has some value, it’s just been easier form them to come up with a way to sell the physical good. It’s understandable, due to path of least resistance but, they really have to get it through their system that in the digital age that physical book or disc is a bigger hindrance to their business. It’s so much easier and cost effective if they could only learn to get over it!Now if they extend that they could use a physical item to provide a value added bonus and make better profit margins from that but most people want the cheap and easy option available!
