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".
Donkey Kong (video game)
"Donkey Kong" is considered to be the earliest video game with a storyline that visually unfolds on screen. The eponymous Donkey Kong character is the game's "de facto" villain. The hero is a carpenter originally unnamed in the Japanese arcade release, later named Jumpman and then Mario. Donkey Kong kidnaps Mario's girlfriend, originally known as Lady, but later renamed Pauline. The player must take the role of Mario and rescue her. This is the first occurrence of the damsel in distress scenario that would provide the template for countless video games to come.
