1985-consoles were a fad, who would buy a console when they can play games for a fraction of the cost at arcades or on a home computer with superior hardware? Next thing you know NES is a massive success that brought back console gaming from the dead and Nintendo is a household name.
1995-Gameboy was a fad, it sold to casuals who wanted to play Tetris on the go and to diehard Nintendo fans who wanted to play handheld versions of their favorite Nintendo franchises. A few years later Gameboy is selling 20+ million per year and Pokemon is a global phenomenon.
2005-Nintendo is becoming irrelevant in the console space and PSP is going to destroy Nintendo's handheld dominance like PS1/PS2 did to their consoles. Next thing you know, DS & Wii are Nintendo's best selling handheld and home console ever and Nintendo is having their most profitable period ever.
2015-Wii was a casual fad and the handheld market is dying to smartphones, there is nothing Nintendo can do to stop this decline and they will soon be completely irrelevant.
When the herd loses its way, the shepard must kill the bull that leads them astray.
