History

Small two way radios were first used in World War II. The citizens' band (CB) radio was born out of the idea that there was a market for inexpensive two way radio service for private aircraft, boats and businesses. As businesses and individuals became licensed to use the frequency by the Federal Communications Commission (FCC), they found that there were all types of people, including truckers, interested in using the frequency. CBs evolved into a mass market product in the 1970s during the oil crisis, independent trucker strikes, and it was popularized by TV, movies and song. CB jargon and the appeal of the independent image of truckers appealed to many motorists who purchased CBs On the highway, truckers use it to relay information on road emergencies, traffic conditions and to stay in touch with the "road community" or base units at truck stops or in the home.
