List of best-selling game consoles




A video game console is a standardized computing device tailored for video gaming that requires a monitor or television set as an output.[2] These self-contained pieces of electronic equipment[2] weigh between 2 and 9 pounds (1–4kg) on average,[3] and their compact size allows them to be easily used in a variety of locations with an electrical outlet.[3] Handheld controllers are commonly used as input devices. Video game consoles may use one or more storage media like hard disk drives, optical discs, and memory cards for content.[3] Each are usually developed by a single business organization.[2] Dedicated consoles are a subset of these devices only able to play built-in games.[4][5] Gaming consoles in general are also described as "dedicated" in distinction from the more versatile personal computer and other consumer electronics.[6][7][8] Sanders Associates engineer Ralph H. Baer along with company employees Bill Harrison and Bill Rusch licensed their television gaming technology to contemporary major TV manufacturer Magnavox. This resulted in Magnavox Odyssey's 1972 release—the first commercially available video game console.[9]
A handheld game console is a lightweight device with a built-in screen, games controls, speakers,[10] and has greater portability than a standard video game console.[3] It is capable of playing multiple games unlike tabletop and handheld electronic game devices. Tabletop and handheld electronic game devices of the 1970s and 1980s are the precursors of handheld game consoles.[11] Mattel introduced the first handheld electronic game with the 1977 release of Auto Race.[12] Later, several companies—including Coleco and Milton Bradley—made their own single-game, lightweight tabletop or handheld electronic game devices.[13] The oldest handheld game console with interchangeable cartridges is the Milton Bradley Microvision in 1979.[14] Nintendo is credited with popularizing the handheld console concept with the Game Boy's release in 1989[11] and continues to dominate the handheld console market.[15][16]

Atari consoles
Forster 2011, p.92: "The test release of the Atari 7800 went by practically unnoticed [...] And so the Atari 7800 collected dust for two years, until the international success of the Nintendo Entertainment System quickly changed the minds of Atari's new management. [...] Atari shipped the now slightly outdated 7800 across the world. [...] Only a few thousand 7800 consoles were shipped in the US during the first marketing attempt."
