Censorship or the suppression of speech or other public communication may take many forms and be conducted by an individual, a body of people, a government, a media outlet, a business entity, or other controlling body. It may take the form of suppressing information that is considered morally objectionable or distasteful, such as the banning of books or pornography or the bleeping of language on television. It may be legalized to protect someone from harm like yelling “Fire!” in a crowded theater or posting hateful or bullying messages on the internet. It may be practiced by the military to keep tactics and intelligence away from the perceived enemy. It may also be used to suppress information that is considered sensitive or private or just inconvenient to the general body of people.
