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 gaming in the United States
The 1970s included the birth of the video game console. The first console released was titled "Magnavox Odyssey" and the foundation of Atari occurred around the same time, marking the start of "Pong's" development. Upon "Pong's" completion it become the hottest selling Christmas product of 1975. The evolution of the console was incredibly rapid. A few years after their invention, consoles received microprocessors and programmable ROM cartridge based games, allowing users the ability to change games by simply switching cartridges. Important consoles released at this time were the "Telstar, Fairchild Channel F., "and "Atari 2600." Arcade games also received advances with the game "Space Invaders", which allowed high scores to be tracked and displayed. A year later the game "Asteroids "built on the idea and gave high scorers the ability to enter initials by their scores.
