But, in fact, CB was a revolution in its time, whose effects are still felt today. Before Citizens' Band was created, you needed a license to be on the air, with almost no exceptions. Radio was seen as Serious Technology For Serious People, nothing for normal folks to fool around with, at least not without government approval. Citizens' Band put an end to that, not by regulatory design but by popular fiat. Originally, a license was required for Citizens' Band, too, but masses of people simply broke the law and operated without a license until the FCC was forced to bow to reality. It was a form of mass civil disobedience that accomplished in its sphere what drug-legalization activists have never been able to accomplish in theirs. No small thing.
And it didn't stop there. Citizens' Band radio became popular because of widespread resistance to another example of regulatory overreach: the unpopular 55-mile-per-hour speed limit. Actually passed in 1974, but popularly identified with Jimmy Carter's "moral equivalent of war," speed limits were for the first time set not for reasons of safety, but for reasons of politics and social engineering. Americans rejected that approach in massive numbers, and entered into a state of more-or-less open rebellion. CB was valuable -- as songs like Convoy! and movies like Smokey and the Bandit illustrated -- because it allowed citizens to spontaneously organize against what they saw as illegitimate authority.10-4, good buddy.
