Microsoft at 50: Key Milestones, Products, and Impact Since 1975

Introduction to Microsoft’s 50-year trajectory

Founded in 1975, Microsoft evolved from a small software startup into one of the world’s largest technology companies by market value and impact. This overview explains who Microsoft is, how it has changed computing, and why its products and platforms remain central to consumers, enterprises, and developers. It focuses on verifiable milestones, products, and outcomes rather than speculation, with comparisons that clarify its scale and role in the technology ecosystem.

1975–1985: Early products and platform foundations

Microsoft was founded in Albuquerque, New Mexico, to create interpreters for the Altair 8800 and later focused on operating systems and languages. Key moves in the 1980s included MS-DOS, Windows 1.0 in 1985, and the Office suite beginnings, establishing software licensing as a core business model.

Smartphones and cloud computing shifted focus from licensed software to services and recurring revenue. Microsoft launched Windows Phone, expanded Xbox and cloud offerings, and grew Azure as a leading cloud platform alongside Amazon Web Services and Google Cloud. Satya Nadella became CEO in 2014, emphasizing cloud-first and mobile-first strategies.
