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".
Nintendo Entertainment Analysis &amp; Development
One of the first games developed by the R&D4 department was "Mario Bros." in 1983, designed and directed by Miyamoto. The department was, however, unable to program the game with such an inexperienced team, and so counted with programming assistance from Gunpei Yokoi and the R&D1 department. One of the first completely self-developed games was "Super Mario Bros.", the sequel to "Mario Bros." The game set standards for the platform genre, and went on to be both a critical and commercial success. In 1986, R&D4 developed "The Legend of Zelda", for which Miyamoto again served as a director. The phenomenal sales of "Super Mario Bros." and "The Legend of Zelda" fueled the expansion of the department with young game designers such as Hideki Konno, Katsuya Eguchi, Kensuke Tanabe, Takao Shimizu, who would later become producers themselves.
