The radio industry includes companies or public service providers who are involved with radio broadcasting or ancillary services. It includes commercial operators who operate and repair certain radiotelephone, television, radar and Morse code radio stations. Radio stations that broadcast via radio waves include AM and FM stations. Federal Communications Commission (FCC) regulates radio broadcasting in the United States. However, there are unlicensed private radio services for personal or business activities of the general public such as the Multi-Use Radio Service and the Family Radio Service. Amateur radio or ham radio is a service in which participants communicate with each other for public service, recreation and self training.
