History of Apple computer

History
Main article: History of Apple Inc.
The company introduced the Apple II microcomputer in March 1977. A few years later, in 1983, it introduced the Lisa, the first commercial personal computer to employ a graphical user interface (GUI), which was influenced in part by the Xerox Alto. Lisa was also the first personal computer to have the mouse. In 1984, the Macintosh was introduced, which arguably advanced the concept of a new user-friendly graphical user interface. Apple's success with the Macintosh became a major influence in the development of graphical interfaces elsewhere, with major computer operating systems, such as the Commodore Amiga, and Atari ST, appearing on the market within two years of the introduction of the Macintosh.

In 1991, Apple introduced the PowerBook line of portable computers. The 1990s also saw Apple's market share fall as competition from Microsoft Windows and the comparatively inexpensive IBM PC compatible computers that would eventually dominate the market. In the 2000s, Apple expanded its focus on software to include professional and prosumer video, music, and photo production solutions, with a view to promoting their products as a "digital hub". It also introduced the iPod, the most popular digital music player in the world.[8]
