The Xbox One is an eighth-generation home video game console developed by Microsoft. 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'. The Xbox One mainly competes against Sony's PlayStation 4 and Nintendo's Wii U and Switch.
