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.
Game &amp; Watch
Game & Watch ( "Gēmu & Uotchi"; called Tricotronic in West Germany and Austria) was a line of handheld electronic games produced by Nintendo from 1980 to 1991. Created by game designer Gunpei Yokoi, each "Game & Watch" features a single game to be played on an LCD screen in addition to a clock, an alarm, or both. . It was the earliest Nintendo product to gain major success.
