Microsoft was founded on April 4, 1975, by Bill Gates and Paul Allen in Albuquerque, New Mexico, initially focused on developing programming languages for the Altair 8800 microcomputer. The company relocated to Bellevue, Washington in 1979 and then to Redmond in 1986, where it has maintained its headquarters ever since.
The company's pivotal moment came in 1980 when IBM selected Microsoft to provide the operating system for its new personal computer. Microsoft acquired QDOS (Quick and Dirty Operating System) and adapted it into MS-DOS, which became the standard operating system for IBM-compatible PCs. This deal established Microsoft as the dominant force in PC software and set the foundation for decades of growth.
Microsoft went public on March 13, 1986, at $21 per share, making both Gates and Allen billionaires. The company launched Windows 1.0 in 1985 and continued developing the Windows operating system through the 1990s, with Windows 95 becoming a cultural phenomenon and establishing the graphical user interface as the standard for personal computing.
Throughout the 1990s and 2000s, Microsoft expanded aggressively into productivity software with Microsoft Office, internet services with Internet Explorer and MSN, gaming with Xbox, and enterprise software. The company faced significant antitrust scrutiny from the US Department of Justice and European regulators regarding its bundling of Internet Explorer with Windows, resulting in a landmark antitrust case that shaped the technology industry's regulatory landscape.
Satya Nadella became CEO in February 2014, succeeding Steve Ballmer and initiating a transformative shift in Microsoft's strategy toward cloud computing, open-source software, and artificial intelligence. Under Nadella's leadership, Microsoft launched Azure as a major cloud platform, acquired LinkedIn in 2016 for $26.2 billion, acquired GitHub in 2018 for $7.5 billion, and made a landmark $69 billion acquisition of Activision Blizzard in 2023, significantly expanding its gaming portfolio.
Microsoft's strategic investment in OpenAI, beginning in 2019 and expanding significantly in 2023 with a reported $10 billion commitment, positioned the company at the forefront of the artificial intelligence revolution. The integration of OpenAI's technology into Microsoft's products through Copilot has become a central pillar of the company's growth strategy.
Microsoft has established comprehensive sustainability initiatives focused on carbon reduction, water conservation, waste reduction, and ethical AI development. The company has been carbon neutral since 2012 and committed to being carbon negative by 2030, removing more carbon from the environment than it emits.
By 2050, Microsoft aims to remove all historical carbon emissions the company has ever produced since its founding in 1975. The company utilizes 100% renewable electricity for its operations and has implemented internal carbon fees that charge business units for their carbon emissions, driving investment in sustainability improvements across the organization.
Microsoft's water strategy focuses on becoming water positive by 2030, meaning the company will replenish more water than it consumes in water-stressed regions where it operates. The company has implemented water reduction technologies and partnered with water conservation organizations to achieve this goal.
In waste management, Microsoft has achieved zero waste to landfill at its major campuses and data centers, implementing comprehensive recycling and composting programs. The company designs products for circularity, focusing on repairability, recyclability, and use of recycled materials.
Microsoft addresses ethical considerations through its AI principles and responsible AI development practices. The company has established six core AI principles: fairness, reliability and safety, privacy and security, inclusiveness, transparency, and accountability. Microsoft conducts regular AI ethics reviews and publishes transparency reports on AI system development and deployment.
The company maintains strong workplace diversity and inclusion programs, publishing annual diversity reports that track progress in representation across gender, race, ethnicity, and other dimensions. Microsoft has also implemented comprehensive supply chain responsibility programs to ensure ethical sourcing and labor practices among its suppliers.
