The Commodore 64 is an 8-bit home computer introduced in January 1982 by Commodore International. The now-prehistoric-looking device was released on to the market at a price of US$595. It got its name from its 64 kilobytes of RAM, and had favorable sound and graphical features when compared to contemporary systems like the Apple II (which was, not surprisingly, priced at US$1200). 

During its lifetime, between 12.5 and 17 million units were sold; making it the best selling personal computer of all time! It outsold the IBM PC compatibles, Apple Inc computers, and Atari 8-bit family computers. 

Approximately 1000 commercial software titles were made for the Commodore 64 including development tools, office productivity applications, and games. Nowadays, the C64 is an endangered species; it’s only used by some computer hobbyists.
