As the crash was happening in the United States, Japan's game industry started to shift its attention from arcade games to home consoles. Within one month in 1983, three new home consoles were released in Japan: the Nintendo Famicom (two years later released in Western markets as Nintendo Entertainment System (NES)), Sega's SG-1000, and Microsoft Japan's MSX hybrid computer-console system, all heralding the third generation of home consoles. These three consoles were extremely popular, buoyed by an economic bubble in Japan. The units readily outsold Atari and Mattel's existing systems, and with both Atari and Mattel focusing on recovering domestic sales, the Japanese consoles effectively went uncontested over the next few years. By 1986, three years after its introduction, 6.5 million Japanese homes—19% of the population—owned a Famicom, and Nintendo began exporting it to the U.S., where the home console industry was only just recovering from the crash. By 1987 the Nintendo Entertainment System was very popular in North America.
