Bullshit. Valve didn't revive shit. The only thing they revived is indie projects that I and many others have no interest it. If I want to play such a game Ill go do it on my iPad. Oh yes, they revived the sale of hats for Team Fortress 2, that was a monumental achievement.
Fact of the matter is that games were being sold just fine before Valve. Valve designed an aggregate to purchase them without a physical copy, and gave you a library to store them in.
If Valve wanted to revive anything then they would attract developers to design Steam Exclusives, but its nothing but indie crap thats already been done.
