Today in History: Commodore 64 Demonstrated at CES, 1982
On January 7, 1982 — 33 years ago today — the Commodore 64 (C64), manufactured by Commodore International, was first shown to a large gathering of potential users at the Consumer Electronics Show (CES) in Las Vegas. The 8-bit, $595-priced computer was substantially less expensive and more powerful than other personal computers on the market offered by IBM, Apple, and Atari — largely because Commodore made its own chips. C64, as its name implies, had about 64K of RAM, technologically superior sound and graphics specifications than available from its competitors, like the Apple II and Atari 800. Consequently, the C64 dominated the home personal computer market for most of the 1980s, and it became the largest selling single computer model in history (up to that time).

Turning the Television into a Monitor:
While other computers on the market required expensive computer monitors, most of which were monotone or offered limited colors, the C64 could be hooked up to a television set just like a gaming console, using a TV/Video switch and featured a range of 16 colors. This made the C64 ideal for families buying their first computer on a limited budget.
