Icom Inc.'s roots are in designing, engineering, and manufacturing highly advanced, compact solid-state radio equipment for use in the amateur (ham) radio industry. The company's product line has since expanded to include communications equipment and products based in the marine, avionics, land mobile and wide-band receiver industries.

Icom America was founded in 1979. With the exception of Cuba, Icom America is responsible for representing Icom products within the entire Western Hemisphere, as well to U.S. Territories in the Pacific.
