Donkey Kong, an arcade game created by Nintendo and released in July 1981, was the first game to allow players to jump over obstacles and gaps; it is widely considered to be the first platformer due to these defining features.[25][26] It introduced Mario 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,[27] and also a handheld version from Coleco in 1982.[28] The game helped cement Nintendo's position as an important name in the video game industry internationally.[29]
