First generation of video game consoles
This was also 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".
Platform game
"Donkey Kong", an arcade game created by Nintendo and released in July 1981, was the first game that allowed players to jump over obstacles and across gaps, making it the first true platformer. It introduced Mario, a modern icon of the genre, under the name Jumpman. "Donkey Kong" was ported to many consoles and computers at the time, notably as the system-selling pack-in game for ColecoVision, and also a handheld version from Coleco in 1982. The game helped cement Nintendo's position as an important name in the video game industry internationally.
