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 World Championships
The first Nintendo World Championships was in 1990, touring 30 American cities. It was based on a custom game cartridge for the Nintendo Entertainment System, which would historically become one of the most rare and valuable NES cartridges. On June 14, 2015, the second Nintendo World Championships took place for its 25th anniversary as part of Nintendo's E3 2015 coverage. The third Nintendo World Championships was held on October 7, 2017.
