Citizens band (CB) radios experienced a sudden burst of fame during 1970s, with the song “Convoy” and a string of movies such as 'Smokey and the Bandit'.


Today, Citizens band (CB) radio service is largely defunct other than for truckers, but new types of radio services - notably FRS - provide similar or better service for individuals and families wanting a convenient two way radios to keep in contact over relatively short distances.
