The XBOX One is a line of home video game consoles developed by Microsoft. Announced in May 2013, it is the successor to XBOX 360 and the third base console in the XBOX series of video game consoles. It was first released in North America, parts of Europe, Australia, and South America in November 2013 and in Japan, China, and other European countries in September 2014. It is the first XBOX game console to be released in China, specifically in the Shanghai Free-Trade Zone. Microsoft marketed the device as an "all-in-one entertainment system", hence the name "Xbox One". An eighth-generation console, it mainly competed against Sony's PlayStation 4 and Nintendo's Wii U and later the Switch.
