What you call inspiration is simply adopting a structure in which the company already ran. Inspiration means something/someone somehow made you think of an new Idea. Its not about copying what was already there, thats only inspiration in cynical terms. But Sony is great at that kind of inspiration, so you might be right.
Huh? They obviously didn't directly copy their music division. Each division was providing completely different products. They were simply inspired by the business philosophy of the music division and adapted it in their own way to make it work for gaming. Your last sentence shows me you're not interested in an actual conversation and are just interested in engaging in childish console war nonsense (and doing a pretty poor job of it since you can't manage to back up your claims). If you have actual evidence, provide it. Otherwise I'm not interested.
