The machine was based on open architecture and a substantial market of third-party peripherals, expansion cards and software grew up rapidly to support it.
The PC had a substantial influence on the personal computer market. The specifications of the IBM PC became one of the most popular computer design standards in the world, and the only significant competition it faced from a non-compatible platform throughout the 1980s was from the Apple Macintosh product line. The majority of modern personal computers are distant descendants of the IBM PC.
