Super Mario Bros. (スーパーマリオブラザーズSūpā Mario Burazāzu?) is a 1985 platform video game developed by Nintendo, published for the Nintendo Entertainment System as a sequel to the 1983 game Mario Bros. In Super Mario Bros., the player controls Mario (and in a two-player game, a second player acts as Mario's brother Luigi) as he travels through the Mushroom Kingdom in order to rescue Princess Toadstool from the antagonist Bowser.
For over two decades, Super Mario Bros. was the best-selling video game of all time (before being outsold by Nintendo's own Wii Sports in 2009), and has sold more than 40 million copies worldwide. It was largely responsible for the initial success of the Nintendo Entertainment System, as well as ending the two-year slump of console game sales in the United States after the video game crash of 1983. As one of Shigeru Miyamoto and Takashi Tezuka's most influential early successes, it has inspired many clones, sequels, and spin-offs. The game's 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 success of Super Mario Bros. has caused it to be ported to almost every one of Nintendo's major gaming consoles. In late 2010, as part of the 25th anniversary of the game's release, Nintendo released special red variants of the Wii and Nintendo DSi XL consoles in differently re-packaged, Mario-themed, and limited edition bundles in all region
