Censorship is the suppression of speech or other public communication which may be considered objectionable, harmful, sensitive, or inconvenient as determined by a government, media outlet, or other controlling body. It can be done by governments and private organizations or by individuals who engage in self-censorship. It occurs in a variety of different contexts including speech, books, music, films, and other arts, the press, radio, television, and the Internet for a variety of reasons including national security, to control obscenity, child pornography, and hate speech, to protect children, to promote or restrict political or religious views, and to prevent slander and libel. It may or may not be legal. Many countries provide strong protections against censorship by law, but none of these protections are absolute and it is frequently necessary to balance conflicting rights in order to determine what can and cannot be censored.
Socrates defied censorship and was sentenced to drink poison in 399 BC for promoting his philosophies. Plato is said to have advocate censorship in his essay on The Republic. The playwright Euripides (480-406 BC) defended the true liberty of freeborn men, the right to speak freely,.
The rationale for censorship is different for various types of information censored:
- Moral censorship is the removal of materials that are obscene or otherwise considered morally questionable. Pornography, for example, is often censored under this rationale, especially child pornography, which is illegal and censored in most jurisdictions in the world.
- Military censorship is the process of keeping military intelligence and tactics confidential and away from the enemy. This is used to counter espionage, which is the process of gleaning military information.
- Political censorship occurs when governments hold back information from their citizens. This is often done to exert control over the populace and prevent free expression that might foment rebellion.
- Religious censorship is the means by which any material considered objectionable by a certain faith is removed. This often involves a dominant religion forcing limitations on less prevalent ones. Alternatively, one religion may shun the works of another when they believe the content is not appropriate for their faith.
- Corporate censorship is the process by which editors in corporate media outlets intervene to disrupt the publishing of information that portrays their business or business partners in a negative light, or intervene to prevent alternate offers from reaching public exposure.
Strict censorship existed in the Eastern Bloc. Throughout the bloc, the various ministries of culture held a tight rein on their writers. Cultural products there reflected the propaganda needs of the state. Party-approved censors exercised strict control in the early years. In the Stalinist period, even the weather forecasts were changed if they had the temerity to suggest that the sun might not shine on May Day. Under Nicolae Ceauşescu in Romania, weather reports were doctored so that the temperatures were not seen to rise above or fall below the levels which dictated that work must stop.
Independent journalism did not exist in the Soviet Union until Mikhail Gorbachev became its leader; all reporting was directed by the Communist Party or related organizations. Pravda, the predominant newspaper in the Soviet Union, had a monopoly. Foreign newspapers were available only if they were published by Communist Parties sympathetic to the Soviet Union.
Possession and use of copying machines was tightly controlled in order to hinder production and distribution of samizdat, illegal self-published books and magazines. Possession of even a single samizdat manuscript such as a book by Andrei Sinyavsky was a serious crime which might involve a visit from the KGB. Another outlet for works which did not find favor with the authorities was publishing abroad.
The People's Republic of China employs sophisticated censorship mechanisms, referred to as the Golden Shield Project, to monitor the internet. Popular search engines such as Baidu also remove politically sensitive search results.
Cuban media is operated under the supervision of the Communist Party's Department of Revolutionary Orientation, which "develops and coordinates propaganda strategies". Connection to the Internet is restricted and censored.
Censorship also takes place in capitalist nations, such as Uruguay. In 1973, a military coup took power in Uruguay, and the State practiced censorship. For example, writer Eduardo Galeano was imprisoned and later was forced to flee. His book Open Veins of Latin America was banned by the right-wing military government, not only in Uruguay, but also in Chile and Argentina.
State secrets and prevention of attention 
In wartime, explicit censorship is carried out with the intent of preventing the release of information that might be useful to an enemy. Typically it involves keeping times or locations secret, or delaying the release of information (e.g., an operational objective) until it is of no possible use to enemy forces. The moral issues here are often seen as somewhat different, as the proponents of this form of censorship argues that release of tactical information usually presents a greater risk of casualties among one's own forces and could possibly lead to loss of the overall conflict.
During World War I letters written by British soldiers would have to go through censorship. This consisted of officers going through letters with a black marker and crossing out anything which might compromise operational secrecy before the letter was sent. The World War II catchphrase "Loose lips sink ships" was used as a common justification to exercise official wartime censorship and encourage individual restraint when sharing potentially sensitive information.
An example of "sanitization" policies comes from the USSR under Joseph Stalin, where publicly used photographs were often altered to remove people whom Stalin had condemned to execution. Though past photographs may have been remembered or kept, this deliberate and systematic alteration to all of history in the public mind is seen as one of the central themes of Stalinism and totalitarianism.
Censorship is occasionally carried out to aid authorities or to protect an individual, as with some kidnappings when attention and media coverage of the victim can sometimes be seen as unhelpful.
Censorship by religion is a form of censorship where freedom of expression is controlled or limited using religious authority or on the basis of the teachings of the religion. This form of censorship has a long history and is practiced in many societies and by many religions. Examples include the Galileo affair, Edict of Compiègne, the Index Librorum Prohibitorum (list of prohibited books) and the condemnation of Salman Rushdie's novel The Satanic Verses by Iranian leader Ayatollah Ruhollah Khomeini.
Educational sources 
The content of school textbooks is often the issue of debate, since their target audience is young people, and the term "whitewashing" is the one commonly used to refer to removal of critical or conflicting events. The reporting of military atrocities in history is extremely controversial, as in the case of The Holocaust (or Holocaust denial), Bombing of Dresden, the Nanking Massacre as found with Japanese history textbook controversies, the Armenian Genocide, the Tiananmen Square protests of 1989, and the Winter Soldier Investigation of the Vietnam War.
In the context of secondary school education, the way facts and history are presented greatly influences the interpretation of contemporary thought, opinion and socialization. One argument for censoring the type of information disseminated is based on the inappropriate quality of such material for the young. The use of the "inappropriate" distinction is in itself controversial, as it changed heavily. A Ballantine Books version of the book Fahrenheit 451 which is the version used by most school classes contained approximately 75 separate edits, omissions, and changes from the original Bradbury manuscript.
In February 2006 a National Geographic Magazine cover was censored by the Nashravaran Journalistic Institute. The offending cover was about the subject of love and a picture of an embracing couple was hidden beneath a white sticker.
Copy, picture, and writer approval 
Copy approval is the right to read and amend an article, usually an interview, before publication. Many publications refuse to give copy approval but it is increasingly becoming common practice when dealing with publicity anxious celebrities. Picture approval is the right given to an individual to choose which photos will be published and which will not. Robert Redford is well known for insisting upon picture approval. Writer approval is when writers are chosen based on whether they will write flattering articles or not. Hollywood publicist Pat Kingsley is known for banning certain writers who wrote undesirably about one of her clients from interviewing any of her other clients.
Creative censorship 
There are many ways that censors exhibit creativity, but a specific variant is of concern in which censors rewrite texts, giving these texts secret co-authors. This form of censorship is discussed in George Orwell's novel Nineteen Eighty-Four.[original research?]
According to a Pew Research Center and the Columbia Journalism Review survey, "About one-quarter of the local and national journalists say they have purposely avoided newsworthy stories, while nearly as many acknowledge they have softened the tone of stories to benefit the interests of their news organizations. Fully four-in-ten (41%) admit they have engaged in either or both of these practices."
Censorship by medium 
Book censorship can be enacted at the national or sub-national level, and can carry legal penalties for their infraction. Books may also be challenged at a local, community level. As a result, books can be removed from schools or libraries, although these bans do not extend outside of that area.
Aside from the usual justifications of pornography and obscenity, some films are censored due to changing racial attitudes or political correctness in order to avoid ethnic stereotyping and/or ethnic offense despite its historical or artistic value. One example is the still withdrawn "Censored Eleven" series of animated cartoons, which may have been innocent then, but are "incorrect" now.
Film censorship is carried out by various countries to differing degrees. For example, only 34 foreign films a year are approved for official distribution in China’s strictly controlled film market.
Music censorship has been implemented by states, religions, educational systems, families, retailers and lobbying groups – and in most cases they violate international conventions of human rights.
Censorship of maps is often employed for military purposes. For example, the technique was used in former East Germany, especially for the areas near the border to West Germany in order to make attempts of defection more difficult. Censorship of maps is also applied by Google maps, where certain areas are grayed out or blacked or areas are purposely left outdated with old imagery.
Internet censorship is control or suppression of the publishing or accessing of information on the Internet. It may be carried out by governments or by private organizations either at the behest of government or on their own initiative. Individuals and organizations may engage in self-censorship on their own or due to intimidation and fear.
The issues associated with Internet censorship are similar to those for offline censorship of more traditional media. One difference is that national borders are more permeable online: residents of a country that bans certain information can find it on websites hosted outside the country. Thus censors must work to prevent access to information even though they lack physical or legal control over the websites themselves. This in turn requires the use of technical censorship methods that are unique to the Internet, such as site blocking and content filtering.
Unless the censor has total control over all Internet-connected computers, such as in North Korea or Cuba, total censorship of information is very difficult or impossible to achieve due to the underlying distributed technology of the Internet. Pseudonymity and data havens (such as Freenet) protect free speech using technologies that guarantee material cannot be removed and prevents the identification of authors. Technologically savvy users can often find ways to access blocked content. Nevertheless, blocking remains an effective means of limiting access to sensitive information for most users when censors, such as those in China, are able to devote significant resources to building and maintaining a comprehensive censorship system.
Views about the feasibility and effectiveness of Internet censorship have evolved in parallel with the development of the Internet and censorship technologies:
- A 1993 Time Magazine article quotes computer scientist John Gillmore, one of the founders of the Electronic Frontier Foundation, as saying "The Net interprets censorship as damage and routes around it."
- In November 2007, "Father of the Internet" Vint Cerf stated that he sees government control of the Internet failing because the Web is almost entirely privately owned.
- A report of research conducted in 2007 and published in 2009 by the Beckman Center for Internet & Society at Harvard University stated that: "We are confident that the [censorship circumvention] tool developers will for the most part keep ahead of the governments' blocking efforts", but also that "...we believe that less than two percent of all filtered Internet users use circumvention tools".
- In contrast, a 2011 report by researchers at the Oxford Internet Institute published by UNESCO concludes "... the control of information on the Internet and Web is certainly feasible, and technological advances do not therefore guarantee greater freedom of speech."
A BBC World Service poll of 27,973 adults in 26 countries, including 14,306 Internet users, was conducted between 30 November 2009 and 7 February 2010. The head of the polling organization felt, overall, that the poll showed that:
- Despite worries about privacy and fraud, people around the world see access to the internet as their fundamental right. They think the web is a force for good, and most don’t want governments to regulate it.
The poll found that nearly four in five (78%) Internet users felt that the Internet had brought them greater freedom, that most Internet users (53%) felt that "the internet should never be regulated by any level of government anywhere", and almost four in five Internet users and non-users around the world felt that access to the Internet was a fundamental right (50% strongly agreed, 29% somewhat agreed, 9% somewhat disagreed, 6% strongly disagreed, and 6% gave no opinion).
The former Soviet Union maintained a particularly extensive program of state-imposed censorship. The main organ for official censorship in the Soviet Union was the Chief Agency for Protection of Military and State Secrets generally known as the Glavlit, its Russian acronym. The Glavlit handled censorship matters arising from domestic writings of just about any kind—even beer and vodka labels. Glavlit censorship personnel were present in every large Soviet publishing house or newspaper; the agency employed some 70,000 censors to review information before it was disseminated by publishing houses, editorial offices, and broadcasting studios. No mass medium escaped Glavlit's control. All press agencies and radio and television stations had Glavlit representatives on their editorial staffs.
Sometimes, public knowledge of the existence of a specific document is subtly suppressed, a situation resembling censorship. The authorities taking such action will justify it by declaring the work to be "subversive" or "inconvenient". An example is Michel Foucault's 1978 text "Sexual Morality and the Law" (later republished as "The Danger of Child Sexuality"), originally published as La loi de la pudeur [literally, "the law of decency"]. This work defends the decriminalization of statutory rape and the abolition of age of consent laws.
When a publisher comes under pressure to suppress a book, but has already entered into a contract with the author, they will sometimes effectively censor the book by deliberately ordering a small print run and making minimal, if any, attempts to publicize it. This practice became known in the early 2000s as privishing (private publishing).
Censorship by country 
Censorship by country collects information on censorship, Internet censorship, Freedom of the Press, Freedom of speech, and Human Rights by country and presents it in a sortable table, together with links to articles with more information. In addition to countries, the table includes information on former countries, disputed countries, political sub-units within countries, and regional organizations.
