The first copyright law was a censorship law. It had nothing to do with protecting the rights of authors, or encouraging them to produce new works. Authors' rights were in no danger in sixteenth-century England, and the recent arrival of the printing press (the world's first copying machine) was if anything energizing to writers. So energizing, in fact, that the English government grew concerned about too many works being produced, not too few. The new technology was making seditious reading material widely available for the first time, and the government urgently needed to control the flood of printed matter, censorship being as legitimate an administrative function then as building roads. The method the government chose was to establish a guild of private-sector censors, the London Company of Stationers, whose profits would depend on how well they performed their function. The Stationers were granted a royal monopoly over all printing in England, old works as well as new, in return for keeping a strict eye on what was printed.
