Censorship is the suppression of speech, public communication, or other information. This may be done on the basis that such material is considered objectionable, harmful, sensitive, or "inconvenient". Censorship can be conducted by governments and private institutions. When an individual such as an author or other creator engages in censorship of their own works or speech, it is referred to as self-censorship. General censorship occurs in a variety of different media, including speech, books, music, films, and other arts, the press, radio, television, and the Internet for a variety of claimed reasons including national security, to control obscenity, pornography, and hate speech, to protect children or other vulnerable groups, to promote or restrict political or religious views, and to prevent slander and libel. Specific rules and regulations regarding censorship vary between legal jurisdictions and/or private organizations. Source: Wikipedia (en)
