  IBM announces the IBM Personal Computer, the smallest and -- with a starting price of $1,565 -- the lowest-priced IBM computer to date. An immediate success, the IBM PC quickly becomes the industry standard, and was one of the reasons Time magazine chose the "personal computer" as its 1982 Man of the Year. The PC also launches a whole industry of "IBM-compatible" clones, software and accessory equipment.

  Though not a spectacular machine by technological standards, the IBM PC brought together all of the most desirable features of a computer into one small machine. It offered 16 kilobytes of user memory (expandable to 256 kilobytes), one or two floppy disks and an optional color monitor. When designing the PC, IBM for the first time contracted the production of its components to outside companies. The processor chip came from Intel and the operating system, called DOS (Disk Operating System) came from a 32-person company called Microsoft.
