Blockbuster - Games retail can't survive without preowned

“If you’re a specialist you need certain margins to run your business. And supermarkets use games as potential loss-leaders, so specialists can’t survive. That’s why there are less games shops than there were three years ago. Without pre-owned, those companies cannot survive." - Blockbuster UK commercial director Gerry Butler

Later on we hear Mr. Butler say that the game industry wasn't complaining about preowned when the industry was growing. I think there wasn't much chatter about it because the industry didn't realize how much cash GameStop was making off of trade-ins!
