What is censorship

I have come up with my own definition of censorship lately and I have used in my recent presentations in Ottawa and in New York City. Let me know what you think about it:

Censorship is controlling the reality by constructing various versions of it.

I think this could provide a start for a different way of analysing and talking about censorship in the media. Especially because it is inclusive enough to cover sophisticated form of censorship such as embedded journalism and disinformation campaign as well as the more primitive forms such as banning publications etc.
