What year marks the founding of the software giant Microsoft?

Microsoft was founded in 1975 by Bill Gates and Paul Allen. This year is significant because it represents the beginning of one of the most influential technology companies in the world, initially focusing on software development and eventually expanding into various technology sectors, including operating systems, productivity software, and cloud computing.

The foundation of Microsoft in 1975 was pivotal for the personal computer revolution, as the company eventually developed the MS-DOS operating system and later Windows, which became the dominant OS in personal computing. This historical context underlines why the year 1975 is a key landmark in the tech industry.

The other years do not correspond to the founding of Microsoft, as the company was not yet in existence in 1973, 1976, or 1978. Each of those years features developments in technology or business, but they do not mark the establishment of this specific company. Hence, understanding the right timeline is crucial for appreciating the history of computing and the evolution of software development that followed.
