The Nintendo Entertainment System, released in Japan in 1983 as the Famicom (Family Computer), marked the second age of home video games and the start of Nintendo's dominance in the video-gaming world. The NES was an 8-bit system with 52-color graphic capability and only 2K of RAM; it became a runaway success. It was the best-selling video game system since the Atari 2600. Super Mario Bros. 3, released in 1988, sold more than 7 million copies. The popularity of the NES eventually made Nintendo Japan's most successful company by 1990.
