IBM introduces its first successful personal computer. The IBM 5150 quickly becomes the industry standard. (In 1973 IBM developed a PC prototype called the "Special Computer, APL Machine Portable" or SCAMP. IBM sold an expensive portable computer in 1975 called the Model 5100.)
The PC-DOS operating system designed for the IBM PC is also marketed separately by Microsoft as MS-DOS. Microsoft's ability to retain the marketing and licensing rights for MS-DOS transforms Bill Gates' small Seattle company.
