Commodore International Corporation was a home computer and electronics manufacturer incorporated in The Bahamas with executive offices in the United States founded in 1976 by Jack Tramiel and Irving Gould. Commodore International, along with its subsidiary Commodore Business Machines, was a significant participant in the development of the home computer industry, and at one point in the 1980s was the world's largest in the industry. The company released its first home computer, the Commodore PET, in 1977; it was followed by the VIC-20, the first ever computer to reach one million units of sales. In 1982, the company developed and marketed the world's best selling computer, the Commodore 64; its success made Commodore one of the world's largest personal computer manufacturers, with sales peaking in the last quarter of 1983 at $49 million. However an internal struggle led to co-founder Tramiel quitting, then rivalling Commodore under Atari Corporation joined by a number of other employees. Wikipedia
