Super Mario Bros is a 1985 platform video game internally developed by Nintendo R&D4 and published by Nintendo as a pseudo-sequel to the 1983 game Mario Bros. It was originally released in Japan for the Family Computer on September 13, 1985, and later that year for the Nintendo Entertainment System in North America, Europe on May 15, 1987 and Australia in 1987. It is the first of the Super Mario series of games. In Super Mario Bros., the player controls Mario and in a two-player game, a second player controls Mario’s brother Luigi as he travels through the Mushroom Kingdom in order to rescue Princess Toadstool from the antagonist Bowser.

In 2005, IGN’s poll named the “pioneering” and “highly influential” title as The Greatest Game Of All Time, considering it to have aided in resurrecting the crashed American video game market of the 1980s.[5] The game’s mid-1980s release served to further popularize the side-scrolling subgenre of the already popular platform video game genre of the early 1980s. In addition to its definitive features, the game has also sold enormously well, and was the best-selling game of all time for a single platform for approximately three decades at over 40 million units, until Nintendo’s Wii Sports took that title. The commercial success of Super Mario Bros. has caused it to be ported to almost every one of Nintendo’s major gaming consoles. Nintendo released special red variants of the Wii and Nintendo DSi XL consoles in re-packaged, Mario-themed, limited edition bundles in late 2010 as part of the 25th anniversary of the game’s release.
