Mario is the most popular video game franchise of all time, selling over 260 million games worldwide. The character Mario appears in over 200 games on every Nintendo console ever made, and in the 1990s, a survey discovered more children recognized Mario than Mickey Mouse. While the Mario series mainly features platform adventures, often involving the safe rescue of Princess Peach, it also includes role-playing, puzzle, racing, and educational games. The franchise further includes television shows, a live-action movie, comics, and promotional materials. Created by Shigeru Miyamoto in 1981, Mario first appeared as the protagonist Jumpman in Donkey Kong. As his name suggests, the character completed levels by jumping over barrels and climbing ladders to rescue the Lady kidnapped by Donkey Kong. In certain advertisements, Jumpman was named Mario, after the landlord of Nintendo of America's offices, and the name stuck. In 1985, Miyamoto produced the Nintendo Entertainment System (NES) game Super Mario Bros. The game takes place in the mythical Mushroom kingdom and stars Mario as he attempts to save Princess Peach from an antagonistic, anthropomorphized turtle named Bowser. Following the success of the original game, Nintendo released Super Mario Bros. 2 in 1988. This game enabled players to choose between controlling Mario, Luigi, Toad, or Princess Peach. Gamers traversed through a mysterious land known as Subcon in order to save its denizens from the clutches of an evil frog king named Wart. Super Mario Bros. 2 was unique for the fact that players had to hit enemies with items like vegetables in order to defeat them, rather than by jumping on them (as is typical in the Mario franchise). Additionally, the game introduced a health bar and was the first Mario game that enabled gamers to choose between four different characters. Super Mario Bros. 2 was adapted from a game called Yume Kojo: Doki Doki Panic (Dream Factory: Heart-Pounding Panic) and sold over seven million copies.
