Microsoft is not just a tech company, but a phenomenon that, in the last four decades, has become the first choice for a host of computer products and services for billions of people around the world. Starting with a turnover of just $16,005 in 1976, Microsoft, ‘the house that Windows built’, had clocked up over $143 billion in revenues in 2020. It also became one of the very few companies to cross the $1 trillion mark in market capitalization! It’s not just the story of its main architects—Bill Gates and Paul Allen—but also of people like Steve Ballmer and Satya Nadella, who have taken Microsoft into an orbit of its own. This book affords us fascinating insights into how modern businesses are built, sustained and scaled up, besides offering an analysis of how different leaders lead the same organization in their own unique ways. The book traces Microsoft’s eventful journey from its early fledgling days to the current dominant status—its first major deal with IBM and the launching of Windows and Office softwares, gaming gadgets, and making forays into other computer products and services like Cloud, mobile phones, computer hardware and artificial Intelligence, covering the entire gamut of information technology.
