History of Nintendo
In 1972, the first commercially available video game console, the Magnavox Odyssey, had a light gun accessory, the Shooting Gallery. This was the first involvement of Nintendo in video games. According to Martin Picard in the "International Journal of Computer Game Research": "in 1971, Nintendo had -- even before the marketing of the first home console in the United States -- an alliance with the American pioneer Magnavox to develop and produce optoelectronic guns for the Odyssey (released in 1972), since it was similar to what Nintendo was able to offer in the Japanese toy market in 1970s".

In 1988, Gunpei Yokoi and his team at Nintendo R&D1 conceived the new Game Boy handheld system, with the purpose of merging the two very successful ideas of the Game & Watch's portability along with the NES's cartridge interchangeability. Nintendo released the Game Boy in Japan on 21 April 1989, and in North America on 31 July 1989. Nintendo of America president Minoru Arakawa managed a deal to bundle the popular third-party game "Tetris" along with the Game Boy, and the pair launched as an instant success.
