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".

In 1995, Nintendo announced that it had sold one billion game cartridges worldwide, ten percent of those being from the "Mario" franchise. Nintendo deemed 1994 the "Year of the Cartridge". To further their support for cartridges, Nintendo announced that Project Reality, which had now been renamed the Ultra 64, would not use a CD format as expected, but would rather use cartridges as its primary media format. Nintendo IRD general manager Genyo Takeda was impressed by video game development company Rare's progress with real-time 3D graphics technology, using state of the art Silicon Graphics workstations. As a result, Nintendo bought a 25% stake in the company, eventually expanding to 49%, and offered their catalogue of characters to create a CGI game around, making Rare Nintendo's first western-based second-party developer. Their first game as partners with Nintendo was "Donkey Kong Country". The game was a critical success and sold over eight million copies worldwide, making it the second best-selling game in the SNES library. In September 1994, Nintendo, along with six other video game giants including Sega, Electronic Arts, Atari, Acclaim, Philips, and 3DO approached the United States Senate and demanded a ratings system for video games to be enforced, which prompted the decision to create the Entertainment Software Rating Board.
