Steam is the reason PC gamers saw the value in all digital, there was still a healthy amount of sales in the PC aftermarket via eBay/Amazon/Half and other places selling games with the installation keys included. That went away once people saw the value in buying games so cheap that the potential resale value didn't matter.Because steam is all digital. All profit.
On consoles physical games still sell a hell of a lot more digital.
Microsoft and Sony can give people those 2 licenses for $72 and not lose any sleep. You are going to have an easier time selling someone a game for $54 straight up over $60 with the potential to get $6 back afterwards. Gamestop doesn't like it? Too bad, they already have what they want in the ability to sell used games.
Remember Steam didn't start out the monster that it did, I can't even remember the first huge summer/winter sale, but I think it might have been 2008/2009? @daze23 @Ciggavelli @2gunsup
It definitely wasn't within the first 2 years after launch.
