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".

The term "electronic game" is commonly understood as a synonym for the narrower concept of the "video game." This is understandable as both electronic games and video games have developed in parallel and the game market has always had a strong bias toward the visual. The first electronic game, in fact, is often cited to be "Cathode-Ray Tube Amusement Device" (1947) a decidedly visual game. Despite the difficulties in creating a visual component to early electronic games imposed by crude graphics, small view-screens, and power consumption, video games remained the primary focus of the early electronic game market.
