It rose to dominate the personal computer operating system market with MS-DOS in the mid-1980s, followed by the Microsoft Windows. The company's 1986 initial public offering, and subsequent rise in its share price, created an estimated three billionaires and 12,000 millionaires from Microsoft employees. Since the 1990s, it has increasingly diversified from the operating system market and has made a number of corporate acquisitions. In May 2011, Microsoft acquired Skype Technologies for $8.5 billion in its largest acquisition to date.[6]
