Super Mario Bros. (???????????? ,Supa Mario Burazazu?) is a platform video game developed by Nintendo in late 1985 and published for the Nintendo Entertainment System as a sequel to the 1983 game Mario Bros.. In Super Mario Bros., the titular character, Mario, saves Princess Toadstool (later renamed Princess Peach) of the Mushroom Kingdom from King Koopa (later renamed Bowser), king of the Koopas. Mario's younger brother, Luigi, is playable by the second player in the game's multiplayer mode, and assumes the same plot role as Mario. To save Princess Toadstool, Mario conquers the eight worlds of the Mushroom Kingdom by going to the castle in each to defeat a minion of King Koopa. To reach each castle, Mario battles through three "sub-worlds" by defeating or avoiding King Koopa's henchmen. If Mario successfully fights his way through the castle and defeats the minion, a Mushroom Retainer (later renamed Toad) is freed. Inside the eighth castle, Mario has a final fight with King Koopa and free Princess Toadstool.
As of late 2008, excluding Game Boy Advance and Virtual Console sales, Super Mario Bros. is the second-best-selling video game of all time (selling 40.24 million copies), surpassed only by Wii Sports. It was largely responsible for the initial success of the Nintendo Entertainment System, as well as ending the two year slump of video game sales in the United States after the video game crash of 1983. As one of Shigeru Miyamoto's most influential early successes, it has inspired many clones, sequels and spin-offs. Mario later became Nintendo's most well-known mascot.[citation needed] Its theme music by Koji Kondo is recognized worldwide, even by those who have not played the game, and has been considered a representation for video game music in general.
The game was succeeded by a direct sequel in Japan and a revision of Yume Kojo: Doki Doki Panic (that introduces other characters from the Mario series) elsewhere in the world. In both cases, the games are titled Super Mario Bros. 2, causing both games to be rereleased in different countries with different titles. There also have been many "alternate" versions of the game, such as All Night Nippon Super Mario Bros., which featured personalities from a famous Japanese radio show[clarification needed] and an arcade game.[clarification needed] The success of Super Mario Bros. has caused it to be ported to almost every one of Nintendo's major gaming consoles, as well as the NEC PC-8801 in the form of Super Mario Bros. Special.
