Handheld game console

A handheld game console is a lightweight, portable device with a built-in screen, games controls and speakers. Handheld game consoles are run on machines of small size allowing people to carry them and play them at any time or place. Unlike video game consoles, the controls, screen and speakers are all part of a single unit.

In 1977, Mattel introduced the first handheld electronic game with the release of Auto Race,. Later, several companies—including Coleco and Milton Bradley—made their own single-game, lightweight table-top or handheld electronic game devices. The oldest true handheld game console with interchangeable cartridges is the Milton Bradley Microvision in 1979.

Nintendo is credited with popularizing the handheld console concept with the release of the Game Boy in 1989, and continues to dominate the handheld console market with successive Game Boy models

The origins of handheld game consoles are found in handheld and tabletop electronic game devices of the 1970s and early 1980s. These electronic devices are capable of playing only a single game, they fit in the palm of the hand or on a tabletop, and they may make use of a variety of video displays such as LED, VFD, or LCD. In 1978, handheld electronic games were described by Popular Electronics magazine as "nonvideo electronic games" and "non-TV games" as distinct from devices that required use of a television screen. Handheld electronic games, in turn, find their origins in the of previous handheld and tabletop electro-mechanical devices such as Waco's Electronic Tic-Tac-Toe (1972) Cragstan's Periscope-Firing Range (1960's), and the emerging optoelectronic-display-driven calculator market of the early 1970s. This synthesis happened in 1976, when "Mattel began work on a line of calculator-sized sports games that became the world's first handheld electronic games. The project began when Michael Katz, Mattel's new product category marketing director, told the engineers in the electronics group to design a game the size of a calculator, using LED (light-emitting diode) technology
