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".
Steve Russell (computer scientist)
In 1962, Russell created and designed "Spacewar!", with the fellow members of the Tech Model Railroad Club at MIT, working on a Digital Equipment Corporation PDP-1 minicomputer. "Spacewar!" is widely considered to be the first digital video game and served as a foundation for the entire video game industry.
