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".
Video game development
True commercial design and development of games began in the 1970s, when arcade video games and first-generation consoles were marketed. In 1971, "Computer Space" was the first commercially sold, coin-operated video game. It used a black-and-white television for its display, and the computer system was made of 74 series TTL chips. In 1972, the first home console system was released called Magnavox Odyssey, developed by Ralph H. Baer. That same year, Atari released "Pong", an arcade game that increased video game popularity. The commercial success of "Pong" led other companies to develop "Pong" clones, spawning the video game industry.
