Microsoft has grown from a small partnership founded in 1975 to become the world's largest software company. While early critics doubted the potential for personal computers and software, Microsoft established itself as the dominant player in PC operating systems and office software. It has faced legal challenges over monopolistic practices but remains highly profitable. Looking ahead, Microsoft is diversifying into new areas like mobile devices, gaming, and online services as the PC market matures, while still working to strengthen its core Windows and Office franchises.
