The Game & Watch series are a total of 60 handheld video games that were released between 1980 and 1991. The games were released a year before Donkey Kong, three years before the Famicom, and a whopping nine years before the Game Boy was released. While not Nintendo's initial entry into the video game market, it was one of their most successful products in the early 80s. After Nintendo started to develop popular series such as Donkey Kong, Mario and The Legend of Zelda, they constructed games based on these titles, and even made games that starred popular characters such as Mickey Mouse and Snoopy. The idea of the Game & Watch was conceived by Gunpei Yokoi.
A multiple of companies help Nintendo create their Game & Watch units, including Mego, CGL, Ji2l, Futuretronics, Bienegraeber&co, and Videopoche. While the games themselves were virtually unchanged, the box that the game came in were different as each one was custom made by the respective company.
Years after the Game & Watch was created, Nintendo honored the franchise by referencing it in the WarioWareseries and making Game & Watch compilations known as the Game & Watch Gallery and Game & Watch Collection series.
