Microsoft

Microsoft Corporation is an American multinational technology corporation headquartered in Redmond, Washington. Microsoft's best-known software products are the Windows line of operating systems, the Microsoft 365 suite of productivity applications, Microsoft 365 suite of productivity applications, 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; it was the world's largest software maker by revenue as of 2022. 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 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 2023. Harvard University classmates Bill Gates and Paul Allen started Microsoft in 1975 to develop a compiler for the Altair 8800, a very primitive early computer. Gates contacted the manufacturer Micro Instrumentation and Telemetry Systems (MITS) and offered to write a program for the new computer. Gates and Allen created an interpreter for BASIC -- which was then a mainframe programming language -- to use with the Altair. MITS hired Gates and Allen in 1975. But by 1976, they left to devote more time to their own fledgling company, Microsoft, which they incorporated in 1981. That year, the company was contracted by IBM to develop an operating system for IBM's personal computer. Called PC-DOS by IBM, Microsoft also marketed its own version, MS-DOS (Microsoft Disk Operating System). The early 1980s saw both IBM's and Microsoft's fortunes soar. Microsoft developed a graphical interface that ran on top of DOS called Interface Manager, later renamed Windows on its release in 1985. This was inspired by the same Xerox PARC research project that Apple used to move an arrow across a graphical desktop.
