The start of a software empire
Microsoft, the American tech giant, was founded 50 years ago, on 4 April 1975, by Harvard dropout Bill Gates and his childhood friend Paul Allen. Since then, the company has evolved from a small startup into the world’s largest software company.
Its early success can be traced back to a pivotal deal in 1975 involving the Altair computer, which inspired the pair to launch the business officially.
That same drive for innovation would later secure Microsoft a breakthrough in 1980 when it partnered with IBM. A collaboration that was supplying the DOS operating system for IBM PCs, a move that turned Microsoft into a household name.
In 1986, Microsoft went public at $21 per share, according to the NASDAQ. A year later, Gates popped up on the billionaire list, the youngest ever to hold the status at the time, at 31 years old.
Microsoft expands its empire
Throughout the 1980s and 1990s, Microsoft’s dominance in the software industry grew rapidly, particularly with the introduction of Windows 3.0 in 1990, which sold over 60 million copies and solidified the company’s control over the PC software market.
Over the decades, Microsoft has diversified its portfolio far beyond operating systems. Its Productivity and Business Processes division now includes the ever-popular Office Suite, which caters to both commercial and consumer markets, and the business-focused LinkedIn platform.
Equally significant is Microsoft’s Intelligent Cloud segment, led by its Azure Cloud Services, now the second-largest cloud platform globally, which has transformed the way businesses manage computing infrastructure.
The strategic pivot into cloud computing has been complemented by a range of other products, including SQL Server, Windows Server, and Visual Studio.
The giant under scrutiny
The company’s journey has not been without challenges. Its rapid rise in the 1990s attracted regulatory scrutiny, leading to high-profile antitrust cases and significant fines in both the USA and Europe.
Triggered by concerns over Microsoft’s growing dominance in the personal computer market, US regulators launched a series of investigations into whether the company was actively working to stifle competition.
The initial Federal Trade Commission probe was soon picked up by the Department of Justice, which filed formal charges in 1998. At the heart of the case was Microsoft’s practice of bundling its software, mainly Internet Explorer, with the Windows operating system.
Critics argued that this not only marginalised competitors like Netscape, but also made it difficult for users to install or even access alternative programs.
From Bill Gates to Satya Nadella
Despite these setbacks, Microsoft has continually adapted to the evolving technological landscape. When Steve Ballmer became CEO in 2000, some doubted his leadership, yet Microsoft maintained its stronghold in both business and personal computing.
In the early 2000s, the company overhauled its operating systems under the codename Project Longhorn.
The initiative led to the release of Windows Vista in 2007, which received mixed reactions. However, Windows 7 in 2009 helped Microsoft regain favour, while subsequent updates like Windows 8 and 8.1 aimed to modernise the user experience, especially on tablets.
The transition from Bill Gates to Steve Ballmer, and later to Satya Nadella in 2014, marked a new era of leadership that saw the company’s market capitalisation soar and its focus shift to cloud computing and AI.
Under Nadella’s stewardship, Microsoft has invested heavily in AI, including a notable $1 billion investment in OpenAI in 2019.
The strategic move, alongside the integration of AI features across its software ecosystem, from Microsoft 365 to Bing and Windows, signals the company’s determination to remain at the forefront of technological innovation.
Microsoft’s push for innovation through major acquisitions and investments
Microsoft has consistently demonstrated its commitment to expanding its technological capabilities and market reach through strategic acquisitions.
In 2011, Microsoft made headlines with its $8.5 billion acquisition of Skype, a move intended to rival Apple’s FaceTime and Google Voice by integrating Skype across Microsoft platforms like Outlook and Xbox.
Other strategic acquisitions played a significant role in Microsoft’s evolution. The company purchased LinkedIn, Skype, GitHub and Mojang, the studios behind Minecraft. In recent years, the company has made notable investments in key sectors, including cloud infrastructure, cybersecurity, ΑΙ, and gaming.
One of the most significant acquisitions was Inflection AI in 2024. This deal bolstered Microsoft’s efforts to integrate AI into everyday applications. Personal AI tools, essential for both consumers and businesses, enhance productivity and personalisation.
