NEC brought the CD format to home console gaming with the TurboGrafx even before Sega CD, but it was Sony that made it an industry standard with the success of the Playstation. Sega did online gaming before Microsoft, but it was Xbox Live that set the standard for what gamers expect when playing online. Both companies have had their hand in creating standards in gaming.
That said, anyone who dismisses what Nintendo has brought to home gaming is simply in denial. Of course they're not infallible (the Virtual Boy, 64DD, etc) but it's flat-out absurd to equate their ability to innovate to merely a few good ideas, lol.
In the end though, everyone just copied Ralph Baer's Brown Box anyway, even Atari, and gaming is all the better for it.
