Since the early 1990s, Microsoft operating systems (first with MS-DOS and then with Windows) and Intel hardware - collectively called 'Wintel' - have dominated the personal computer industry, and today the term "PC" normally refers to the ubiquitous Wintel platform. Alternatives to Windows occupy a minority share of the industry; these include the Mac platform from Apple (running the macOS operating system), and free and open-source, Unix-like operating systems, such as Linux. Other notable platforms until the 1990s were the Amiga from Commodore, and the PC-98 from NEC.
