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 video game consoles
The Game Boy was the first handheld game console sold by Nintendo that featured interchangeable cartridges for each game, unlike the Game & Watch that had a different system for each game. Released in 1989 in Japan, it is one of the world's best-selling game console lines, with over 100 million units sold worldwide. The classic Game Boy was sold in a number of different revisions and variations, including the streamlined Game Boy Pocket and the Game Boy Light in Japan. In 1998, Nintendo released the Game Boy Color, a new Game Boy platform with color graphics. Combined, the Game Boy and Game Boy Color sold 118.69 million units worldwide.
