Super mario bros is a platform game developed by Nintendo in late 1985 and published for the Nintendo Entertainment System, a sequel to the 1983 game, Mario Bros. In Super Mario Bros., Italian plumber Mario must save Princess Peach (Princess Toadstool in the US version) of the Mushroom Kingdom from the evil King Koopa (later known as Bowser). In two-player mode, Mario is aided in his quest by his brother, Luigi. In order to save Princess Peach, the Mario Bros. must conquer the eight worlds that comprise the Mushroom Kingdom. Mario (or Luigi) must make his way to the castle in each world and defeat one of the Bowser's evil minions. In order to reach each castle Mario or Luigi must battle through three "sub-worlds" by either destroying or avoiding Bowser's henchmen. If Mario or Luigi successfully fights his way through the castle and defeats the evil minion, a Mushroom Retainer (later called Toad), is freed. Inside the eighth castle, the Mario Bros. will find Princess Peach.

As of 2008, Super Mario Bros. is the best selling video game of all time (selling over 40 million copies to date).[1] 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. One of Shigeru Miyamoto's most influential early successes, it has inspired countless imitators, two direct sequels, and many spinoffs, as well as an entire video game series. Mario went on to become Nintendo's most well-known mascot. The 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 by a slight revision of Yume Kōjō: 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 re-released in different countries under 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, as well as an arcade game. 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.
