Fourth generation of video game consoles
Nintendo executives were initially reluctant to design a new system, but as the market transitioned to the newer hardware, Nintendo saw the erosion of the commanding market share it had built up with the Nintendo Entertainment System. Nintendo's fourth-generation console, the Super Famicom, was released in Japan on November 21, 1990; Nintendo's initial shipment of 300,000 units sold out within hours. The machine reached North America as the Super Nintendo Entertainment System on August 23, 1991, and Europe and Australia in April 1992.
Platform game
Nintendo's platform game "Super Mario Bros.", released for the Nintendo Entertainment System in 1985, became the archetype for many platformers to follow. The title was bundled with Nintendo systems in North America, Japan, and Europe, and went on to sell over 40 million copies, according to the 1999 Guinness Book of World Records. Its success as a pack-in led many companies to see platform games as vital to their success, and contributed greatly to popularizing the genre during the 8-bit console generation.
