Xbox Series X (Refurbished) – Microsoft

Microsoft Corporation is an American multinational corporation and technology company headquartered in Redmond, Washington. Its best-known software products are the Windows line of operating systems, the Microsoft 365 suite of productivity applications, the Azure cloud computing platform and the Edge web browser. Its flagship hardware products are the Xbox video game consoles and the Microsoft Surface lineup of touchscreen personal computers. Microsoft ranked No. 14 in the 2022 Fortune 500 rankings of the largest United States corporations by total revenue; and it was the world's largest software maker by revenue in 2022 according to Forbes Global 2000. It is considered one of the Big Five American information technology companies, alongside Alphabet (parent company of Google), Amazon, Apple, and Meta (parent company of Facebook).

Microsoft was founded by Bill Gates and Paul Allen on April 4, 1975, to develop and sell BASIC interpreters for the Altair 8800. It rose to dominate the personal computer operating system market with MS-DOS in the mid-1980s, followed by Windows. The company's 1986 initial public offering (IPO) and subsequent rise in its share price created three billionaires and an estimated 12,000 millionaires among Microsoft employees. Since the 1990s, it has increasingly diversified from the operating system market and has made several corporate acquisitions, the largest being the acquisition of Activision Blizzard for $68.7 billion in October 2023, followed by its acquisition of LinkedIn for $26.2 billion in December 2016, Nuance Communications for $16 billion in March 2022, and its acquisition of Skype Technologies for $8.5 billion in May 2011.

As of 2015, Microsoft is market-dominant in the IBM PC compatible operating system market and the office software suite market, although it has lost the majority of the overall operating system market to Android. The company also produces a wide range of other consumer and enterprise software for desktops, laptops, tabs, gadgets, and servers, including Internet search (with Bing), the digital services market (through MSN), mixed reality (HoloLens), cloud computing (Azure), and software development (Visual Studio).

Steve Ballmer replaced Gates as CEO in 2000 and later envisioned a "devices and services" strategy. This unfolded with Microsoft acquiring Danger Inc. in 2008, entering the personal computer production market for the first time in June 2012 with the launch of the Microsoft Surface line of tablet computers, and later forming Microsoft Mobile through the acquisition of Nokia's devices and services division. Since Satya Nadella took over as CEO in 2014, the company has scaled back on hardware and instead focused on cloud computing, a move that helped the company's shares reach their highest value since December 1999. Under Nadella's direction, the company has also heavily expanded its gaming business to support the Xbox brand, establishing the Microsoft Gaming division in 2022, dedicated to operating Xbox in addition to its three subsidiaries (publishers). Microsoft Gaming is the third-largest gaming company in the world by revenue as of 2024.

In 2018, Microsoft became the most valuable publicly traded company in the world, a position it has repeatedly traded with Apple in the years since. In April 2019, Microsoft reached a trillion-dollar market cap, becoming the third U.S. public company to be valued at over $1 trillion after Apple and Amazon, respectively. As of 2024, Microsoft has the third-highest global brand valuation.

Microsoft has been criticized for its monopolistic practices and the company's software has been criticized for problems with ease of use, robustness, and security.

Microsoft is one of only two U.S.-based companies that has a prime credit rating of AAA.

Microsoft recognizes seven trade unions representing 1,750 workers in the United States at its video game subsidiaries Activision Blizzard and ZeniMax Media. US workers have been vocal in opposing military and law-enforcement contracts with Microsoft. Bethesda Game Studios is unionized in Canada. Microsoft South Korea recognizes its union since 2017. German employees have elected works councils since 1998.

X, or x, is the twenty-fourth letter of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ex (pronounced ), plural exes.

Xbox is a video gaming brand that consists of five home video game consoles, as well as applications (games), streaming service Xbox Cloud Gaming, and online services such as the Xbox network and Xbox Game Pass. The brand is produced by Microsoft Gaming, a division of Microsoft.

The brand was first introduced in the United States in November 2001, with the launch of the original Xbox console. The Xbox branding was formerly, from 2012 to 2015, used as Microsoft's digital media entertainment brand replacing Zune. In 2022, Microsoft expanded its gaming business and reorganized Xbox to become part of its newly formed Microsoft Gaming division. Under Microsoft Gaming, Xbox's first-party publishers are Xbox Game Studios, ZeniMax Media (Bethesda Softworks), and Activision Blizzard (Activision, Blizzard Entertainment, and King), who own numerous studios and successful franchises.

The original device was the first video game console offered by an American company after the Atari Jaguar stopped sales in 1996. It reached over 24 million units sold by May 2006. Microsoft's second console, the Xbox 360, was released in 2005 and has sold 86 million units as of October 2021. The third console, the Xbox One, was released in November 2013 and has sold 58 million units. The fourth line of Xbox consoles, the Xbox Series X and Series S, were released in November 2020. The head of Xbox is Phil Spencer, who succeeded former head Marc Whitten in late March 2014.
