On September 1, 1982, the Commodore 64 was launched, named for its 64 kilobytes of memory. It was the first computer with 64K of memory to sell for under $600. The exact date of the C-64's first shipment is unclear; prototypes were shown at the January 1982 Consumer Electronics Show, but production-ready models were not available at that time. Some engineers referenced in Brian Bagnall's books suggest that some units shipped in August, while Michael Tomczyk's book, The Home Computer Wars, states the official launch date as September 1. Given that Tomczyk was writing shortly after the launch, his date is likely accurate. Commodore did not sell directly to consumers, so units would have needed to be shipped in August for sales to occur on the launch date.
The initial units were built in Santa Clara, California, but due to quality control issues, production was outsourced to the Japanese company Kentron, which began mass production of the C-64 by January 1983. Within six months of its launch, Commodore sold approximately half a million units, and by the end of its fiscal year in 1984, around 5 million units had been sold. The Commodore 64 became the best-selling computer of all time, with total sales estimated at about 12.3 million units, or approximately 10.6 million units if the C-128 is considered a separate product.
At the time of its release, the C-64 was not considered cheap by modern standards. In 1984, a C-64 with a disk drive typically cost around $450, with the Atari 800XL being the only comparable computer in terms of price and capability. However, Atari faced supply chain issues in 1983, making the Commodore 64 more accessible.
The C-64's success can be attributed to its affordability and memory capacity. Its predecessor, the VIC-20, was the first computer to sell a million units due to its color display priced under $300. Commodore anticipated both the VIC-20 and C-64 would have a shelf life of about three years, which proved accurate for the VIC-20, but the C-64 continued to sell around 700,000 units annually until the end of the decade, remaining in demand even in 1993.
The C-64 underwent several compromises to achieve its price point, including a slower disk drive due to a last-minute design change and limited modem support, as demand for modems was low in 1982. It featured 16-color graphics at resolutions of 160x200 or 320x200 and had eight sprites, which were beneficial for game programming. The sound chip, designed by Bob Yannes, allowed for three-voice sound, providing more flexibility in volume control compared to competing chips.
Creative programmers were able to produce impressive video and audio effects on the C-64, leading to continued software development even as more powerful computers emerged. The C-64 fostered a generation of programmers, with many individuals learning to program and repair the machine, leading to careers in technology.
Jack Tramiel, the CEO of Commodore at the time of the C-64's launch, often expressed joy upon hearing stories of how the C-64 influenced people's careers in technology. The C-64 was accessible to many, making it a viable option for those who could afford it.
The C-64 was not only used for gaming; it also served educational purposes, allowing users to complete homework and print assignments. The concepts learned on the C-64 remain relevant in today's technology landscape.
In 2025, a YouTuber who grew up with a C-64 acquired the Commodore brand and licensed an FPGA-based C-64 replacement motherboard, leading to a limited production run of the C-64, which sold around 19,000 units. This demonstrates the enduring legacy of the Commodore 64, even more than 30 years after its last production run.
