Shigeru Miyamoto.

Miyamoto.

Atari could be up there, but they also almost killed the industry. Nintendo brought it back, thanks mostly to Miyamoto and his games/vision.

Depends on who you ask, but I'll say Shigeru Miyamoto

I'd say Atari, Nintendo and Sony, about equally.

The entrance of each in the market brought about a huge increase in the popularity of gaming, and reinvented the relationship between console manufacturers and game developers.

I came here to say that.

It'd be better if we did it on a Decade basis, because my answer would be Miyamoto, but in the last 15 years my answer would be different.

If gamers wouldn't have bought the fucking thing gaming would have died faster than Disco.

Legend of Zelda for battery back-up/the ability to save games.

I would say Miyamoto for a specific individual just because he created an iconic character that was the resurgence of video games. And also since he's really the only famous one I know much about.

As far as a company goes, all three of the big companies have made incredible strides to advance the industry from a children's toy to a recognized art and entertainment medium. Each in a specific way.

I'd go with Sony.
