Commodore was an American computer company (1955–1994) founded in West Chester, Pennsylvania by businessman Jack Tramiel. Tramiel—famous for his combative business style, his talent for spotting emerging markets, and his colorful sayings—at first sold and repaired typewriters. But his Commodore Business Machines company later branched out into other business areas, including electronic calculators.

When electronics companies began manufacturing their own calculators in the 1970s, Commodore suffered the first of their many business setbacks and nearly went bankrupt. But they learned their lesson and followed the competition by buying their own electronics manufacturing company, MOS Technology, who specialized in the design of computer chips. This move allowed Commodore to cut production costs and maintain quality. It also brought in talented engineers like the legendary Chuck Peddle, who designed the hugely popular 6502 CPU. It cost a fraction of rival processors and formed the basis of Commodore’s entire 8-bit home computer range throughout the 70s and 80s.

Shortly after acquiring MOS, Commodore introduced the PET 2001, a home/business/education computer that (unlike other computers of its day) came with a processor, keyboard, monitor, and cassette storage all bundled into a single unit. It proved instantly popular, and Commodore kept adding improved models to the range with bigger memory, better keyboards, and better screens. These PETs, with their characteristic white cases and green screens, can still be spotted as background props in TV reruns and old movies.

In 1981, Commodore released the VIC 20, the first widely available color computer and the first to sell one million units. Its follow-up, the C64, enjoyed even greater success, and over thirty years later it remains the best-selling computer of all time. Commodore continued to push the boundaries of low-cost high-tech with their Amiga range of multimedia computers, which wowed 1980s computer buyers. But despite their continued innovation, Commodore never again enjoyed their earlier success.

By 1994, boardroom wrangling, Tramiel’s waning influence over his company, the ups-and-downs of the home computer market, and the new PC standard had all pushed Commodore into voluntary liquidation. Commodore and its product names, such as C64 and AMIGA, were sold to Escom (1995-96), Tulip (1997-2004), and Yeahronimo Media Ventures Inc. (AKA Commodore International Corporation or Commodore Holdings B.V. (since 2005)), Commodore Gaming (2007), and Commodore USA (2010-2012). Today (2019) Commodore computers are used and developed by enthusiasts.

For many people, the Commodore name is a fond reminder of the Golden Age of home computing.
