“What is censorship? Censorship is a form of prohibition and punishment. Ever since the 15th century products of the printing press have been subject to censorship and since the 20th century the same has applied to film, radio, television and the Internet. Censorship thus relates to public communication and content in word, image and sound.” - An excellent overview from the Persmuseum in Amsterdam. Many of the examples are from Holland, but that doesn’t take away from a look at censorship from 1600 until today.
