Influential early computers came from Commodore. The Commodore PET (Personal Electronic Transactor) was introduced at the 1977 West Coast Computer Faire. Commodore produced a long line of inexpensive personal computers that brought computers to the masses. The Commodore VIC-20 was the first computer to sell 1 million units! In 1982, the VIC-20 was the best-selling computer of the year, with 800,000 machines sold. One million had been sold by the end of the year and at one point, 9000 units a day were being produced. That summer, Commodore unveiled the Commodore 64, a more advanced machine with 64 KB of RAM and considerably improved sound and graphics capabilities. Sales were slow at first due to reliability problems and lack of software, but by the middle of 1983, the latter had turned into a flood and VIC-20 sales abruptly plunged. It was quietly discontinued in January 1985.
