Throughout their four decades as a console manufacturer, Nintendo have achieved multiple periods of immense success.
In the NES era their share of the console market was at an all time high and they dominated all competition, to the point where for much of the English speaking world at least, "Nintendo" was synonymous with video games.
In the Wii/DS era they led both the home console and handheld markets and sold a gargantuan 255 million systems in a single generation; a feat no other manufacturer has even come close to, and which may never be topped.
