It depends.
Wii and DS both revolutionized the gaming industry. Sure the Atari and stuff started it, but those two changed it dramatically.
Miyamoto created Mario and he is the most iconic and known video game characters ever made.
So I would have to say Nintendo has been one of the most influential and has done a LOT to gaming because they aren't afraid to take risks, regardless if they succeed (Wii, DS) or fail (Wii U) .
