The Macintosh, marketed as Mac, is a line of personal computers (PCs) designed, developed, and marketed by Apple Inc. It is targeted mainly at the home, education, and creative professional markets.
Steve Jobs introduced the Macintosh 128K on January 24, 1984. This was the first mass-market personal computer featuring a graphical user interface and mouse. The 128 was followed by numerous updated models also based on the Motorola 68000 family processors, producing a family of products in the Macintosh lineup. Although the aggressively priced IBM Personal Computer soon overtook Apple in sales. Macintosh systems found success in education and desktop publishing and kept Apple as the second-largest PC manufacturer until 1994 when it was overtaken by Compaq.
