Most popular PC ever, and one dud
Commodore scored a major hit in 1982 with the Commodore 64, or C64, which lasted 11 years and sold at least 17 million units, enough to
earn the Guinness Book of World Records
title as the best-selling computer of all time. At $595, it was relatively cheap and inspired thousands of software titles.
In 1983 Apple introduced the Lisa, the first PC with a graphical user interface. While the innovative machine found a customer in NASA, its $10,000 price tag and reputation for slowness helped make the Lisa a commercial failure. 1983 wasnt a total loss in the personal computer market, as Compaq launched a successful business with the introduction of the first PC clone, based on the same software as the IBM PC.
