25-Year PC Anniversary Statistics
IBM-Compatible PC Sales have topped 1.5B units Worth $B 3,100.

August 14, 2006 -
The IBM PC was announced on August 12, 1981 and became available for sale two months later. Because IBM encouraged other companies to develop IBM-compatible PCs, it quickly became a standard for the whole PC industry. Compaq introduced the first IBM-compatible PC in January 1983 and over 100 other companies followed in the next decade. In the early 1990s Microsoft wrestled away IBM’s leadership of the PC standard and it became Windows-compatible PCs.

The next table shows the 25-year growth of the IBM PC and the industry it created. The data includes 5-year periods for PC unit sales and PC retail value. The sales started slowly with 5.7M units from 1981 to 1985, which grew to 855M units in the last 5-year period ending August 2006.
