How are censorship and the Council of Trent related?

Censorship when people block out certain media, such as parents blocking all the MA tv rated channels so their kids won't watch it.

At The Council of Trent, they made a a list of certain books that were banned.

The connection between censorship and The Council of Trent is a simple one, some books were censored to the public when people met for the council.

But most importantly the Council of Trent set up a system where a book particularly The Bible, was reviewed by an expert and approved by a Bishop. Thus anyone could know that a Bible had not been tampered with by one of the new protestant heresies, but was complete and did not contain any unauthorized additions. These are still printed inside the title page to this day and are known as the Imprimatur (bishop's license meaning "let it be printed"), and the Nihil Obstat (diocesan censor approval "nothing hinders [it from being printed]).
