Different models [of Game & Watch] were manufactured, with some having two screens and a clam-shell design (the Multi Screen Series). The Game Boy Advance SP, Nintendo DS, and Nintendo 3DS later reused this design.
The original arcade Donkey Kong game was created when Shigeru Miyamoto was assigned by Nintendo to convert Radar Scope, a game that had been released to test audiences with poor results, into a game that would appeal more to Americans. The result was a major breakthrough for Nintendo and for the videogame industry [and later] Miyamoto created a greatly simplified version for the Game & Watch multiscreen.
From 1992 until 2016, Nintendo was also the majority shareholder for the Seattle Mariners of Major League Baseball.
