Reading The Master Switch: The Rise and Fall of Information Empires, a book about the telecommunication industry in the US from the telephone onwards, I learnt something about censorship in Hollywood. Between 1930 and 1968, the film industry imposed a set of moral guidelines known as the Motion Picture Production Code on itself, out of fear of regulation. Among the forbidden things were swearing, “Any licentious or suggestive nudity – in fact or in silhouette,” White slavery, and Miscegenation.
There was also a list of topics that were to be treated very carefully, such as “Theft, robbery, safe-cracking, and dynamiting of trains, mines, buildings, etc. (having in mind the effect which a too-detailed description of these may have upon the moron),” Sympathy for criminals, Attitude toward public characters and institutions, and The institution of marriage. The industry also enforced the code itself.
It is fascinating that this was official policy. Of course it should come as no surprise that some things were not exactly right in the US of that time. As regards film censorship, Norway has also set itself up for some serious ridicule (in 1980!).
