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".
Electronic game
A personal computer video game (also known as a computer game or simply PC game) is a video game played on a personal computer, rather than on a video game console or arcade machine. The vast majority of computer games today are video games, and since the earliest days of the medium, visual displays such as the cathode ray tube have been used to relay game information.
