Nintendo
In 1975, Nintendo moved into the video arcade game industry with "EVR Race", designed by their first game designer, Genyo Takeda, and several more games followed. Nintendo had some small success with this venture, but the release of "Donkey Kong" in 1981, designed by Miyamoto, changed Nintendo's fortunes dramatically. The success of the game and many licensing opportunities (such as ports on the Atari 2600, Intellivision and ColecoVision) gave Nintendo a huge boost in profit and in addition, the game also introduced an early iteration of Mario, then known in Japan as Jumpman, the eventual company mascot.

Nintendo's first venture into the video gaming industry was securing rights to distribute the Magnavox Odyssey video game console in Japan in 1974. Nintendo began to produce its own hardware in 1977, with the Color TV-Game home video game consoles. Four versions of these consoles were produced, each including variations of a single game (for example, Color TV Game 6 featured six versions of "Light Tennis").
