How does censorship work today in the media?
Wikipedia's definition of censorship is:
Censorship is the suppression of speech, public communication or other information which may be considered objectionable, harmful, sensitive, politically incorrect or inconvenient as determined by governments, media outlets, authorities or other such entities.
Censorship can work in two ways (or more).
1. Can censor inappropriate things such as nudity, gore, profanity, etc.
2. Can also censor information or news that we get from the media, things that we read too, like books.
