The well-known video game brand Xbox was created and is owned by Microsoft. The brand of video game consoles known as Xbox began in the United States in November 2001 with the release of the original Xbox console. In addition to hardware, Xbox provides a range of services and goods, such as software, the Xbox Cloud Gaming streaming service, the Xbox network, the Xbox Game Pass, and the Xbox Game Studios development studio.

After the Atari Jaguar was discontinued in 1996, the first video game system offered by an American firm was the original Xbox, which represented a key turning point. It has sold more than 24 million copies by May 2006. Microsoft introduced the Xbox 360 in 2005 as a successor to the original, and by October 2021, 86 million copies had been sold. The Xbox One and Xbox Series X and Series S consoles that came after it carried on the brand's tradition of excellence and innovation in the video game industry. Xbox's current CEO, Phil Spencer, assumed over in late March 2014.

Xbox has continually changed throughout its existence, adjusting to the shifting gaming scene. The company has expanded its mission from its early emphasis on console technology, emphasising the value of players and the gaming experience. Initiatives like the 2019 rename of Microsoft Studios to Xbox Game Studios demonstrate this player-centric strategy. With its top-notch gaming systems and services, Xbox is maintaining its position as a dominant force in the gaming market as it expands its user base internationally.
