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".
Pong
"Pong" was the first commercially successful video game, which helped to establish the video game industry along with the first home console, the Magnavox Odyssey. Soon after its release, several companies began producing games that copied its gameplay, and eventually released new types of games. As a result, Atari encouraged its staff to produce more innovative games. The company released several sequels which built upon the original's gameplay by adding new features. During the 1975 Christmas season, Atari released a home version of "Pong" exclusively through Sears retail stores. It also was a commercial success and led to numerous copies. The game has been remade on numerous home and portable platforms following its release. "Pong" is part of the permanent collection of the Smithsonian Institution in Washington, D.C. due to its cultural impact.
