Censorship

n. criticism; suppression of material deemed objectionable

Censorship is defined as the removal and/or withholding of information from the public by a controlling group or body. Typically censorship is done by governments, religious groups, corporations, or the mass media, although other forms of censorship exist. The withholding of  official secrets, commercial secrets, intellectual property, and privileged lawyer-client communication is not usually described as censorship when it remains within reasonable bounds. Because of this, the term "censorship" often carries with it a sense of untoward, inappropriate or repressive secrecy.
