The Macintosh, or Mac, is a series of personal computers designed, developed, and marketed by Apple Inc. Steve Jobs introduced the original Macintosh computer on January 24, 1984. This was the first mass-market personal computer featuring an integral graphical user interface and mouse. This first model was later renamed to "Macintosh 128k" for uniqueness amongst a populous family of subsequently updated models which are also based on Apple's same proprietary architecture. The Macintosh product family has been collectively and singularly nicknamed "Mac" or "the Mac" since the development of the first model. The Macintosh, however, was expensive, which caused it to be overtaken in sales by the aggressively priced IBM Personal Computer and its accompanying clone market. Macintosh systems still found success in education and desktop publishing and kept Apple as the second-largest PC manufacturer for the next decade. In the 1990s, improvements in the rival Wintel platform, notably with the introduction of Windows 3.0, gradually took market share from the more expensive Macintosh systems.
