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".

Computer Othello (June 1978) is a clone of the board game "Reversi". It was the first game produced by Nintendo R&D1, the team that later produced the first "Mario", "Donkey Kong", "Duck Hunt", and "Kid Icarus" games. R&D1 was led by Gunpei Yokoi, who later created the Game Boy, and included "Mario" and "Legend of Zelda" creator Shigeru Miyamoto.
