And basically anything Nintendo pushes as a console gimmick. It's not that the tech immediately goes from research to broadly accessible, but rather that they tend to take old tech that no one saw as having profitable consumer applications and find one for it. In that way, as far as consumers are concerned, it goes from unknown to widely-used without making a stopover in early-adapter purgatory.
And I see that Nintendo has apparently sold an extremely impressive number of consoles (https://www.nintendolife.com/news/2019/11/nintendo_has_now_s...). But even if everyone only bought one console each, that's only about 10% of world population.
This may be a little unfair, but I do wonder if there isn't a tendency to consider a technology to be widely available when it becomes available to you and the folks farther back in the line don't count or aren't relevant.
In any case, you said "important," not "widely available," and yes, Nintendo's products are hugely important. Many of today's technological advancements can be traced back to their proving that a given use case for a primitive version of a given technology was viable.
I will also note that my original comment was in response to someone who is "more interested in tech for the other 95%".
