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, private institutions and other controlling bodies. Governments and private organizations may engage in censorship. Other groups or institutions may propose and petition for censorship.https://www.aclu.org/other/what-censorship "What Is Censorship", ACLU When an individual such as an author or other creator engages in censorship of his or her 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

and libel. Direct censorship may or may not be legal, depending on the type, location, and content. Many countries provide strong protections against censorship by law, but none of these protections are absolute and frequently a claim of necessity to balance conflicting rights is made, in order to determine what could and could not be censored. There are no laws against self-censorship.

The details of Socrates's conviction are recorded by Plato as follows. In 399 BC, Socrates went on

Rationale and criticism

Censorship has been criticized throughout history for being unfair and hindering progress. In a 1997 essay on Internet censorship, social commentator Michael Landier claims that censorship is counterproductive as it prevents the censored topic from being discussed. Landier expands his argument by claiming that those who impose censorship must consider what they censor to be true, as individuals believing themselves to be correct would welcome the opportunity to disprove those with opposing views. Censorship is often used to impose moral values on society, as in the censorship of material considered obscene. English novelist
E. M. Forster Edward Morgan Forster (1 January 1879 – 7 June 1970) was an English author, best known for his novels, particularly ''A Room with a View'' (1908), ''Howards End'' (1910), and ''A Passage to India'' (1924). He also wrote numerous short stori ...
was a staunch opponent of censoring material on the grounds that it was obscene or immoral, raising the issue of moral subjectivity and the constant changing of moral values. When the 1928 novel '' Lady Chatterley's Lover'' was put on trial in 1960, Forster wrote: Proponents have sought to justify it using different rationales for various types of information censored: * Moral censorship is the removal of materials that are
obscene An obscenity is any utterance or act that strongly offends the prevalent morality of the time. It is derived from the Latin ''obscēnus'', ''obscaenus'', "boding ill; disgusting; indecent", of uncertain etymology. Such loaded language can be us ...

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.

Economic induced censorship

Economic induced censorship is a type of censorship enacted by economic markets to favor, and disregard, types of information. Economic induced censorship, is also caused, by market forces which privatize and establish commodification of certain information that is not accessible by the general public, primarily because of the cost associated with commodified information such as academic journals, industry reports and pay to use repositories. The concept was illustrated as a censorship pyramid that was conceptualized by primarily Julian Assange, along with Andy Müller-Maguhn,

Self-censorship

Self-censorship is the act of censoring or classifying one's own discourse. This is done out of fear of, or deference to, the sensibilities or preferences (actual or perceived) of others and without overt pressure from any specific party or institution of authority. Self-censorship is often practiced by film producers, film directors,

. 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." Threats to media freedom have shown a significant increase in Europe in recent years, according to a study published in April 2017 by the Council of Europe. This results in a fear of physical or psychological violence, and the ultimate result is self-censorship by journalists.


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.

Books

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 typically extend outside of that area.


Films

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. Film censorship is achieved by censoring the producer or restricting a state citizen. For example, in China the film industry censors LGBT related films. Filmmakers must resort in finding funds within international investors such as the “Ford Foundations” and or produce through an independent film company.


Music

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.

Moath al-Alwi is a Guantanamo Bay prisoner who creates model ships as an expression of art. Alwi does so with the few tools he has at his disposal such as dental floss and shampoo bottles, and he is also allowed to use a small pair of scissors with rounded edges. A few of Alwi's pieces are on display at John Jay College of Criminal Justice in New York. There are also other artworks on display at the College that were created by other inmates. The artwork that is being displayed might be the only way for some of the inmates to communicate with the outside. Recently things have changed though. The military has come up with a new policy that won't allow the artwork at Guantanamo Bay Military Prison to leave the prison. The art work created by Alwi and other prisoners is now government property and can be destroyed or disposed of in whatever way the government choose, making it no longer the artist's property.

The Degenerate Art Exhibition is a historical instance that's goal was to advertise Nazi values and slander others.


Internet

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.''Freedom of Connection, Freedom of Expression: The Changing Legal and Regulatory Ecology Shaping the Internet''

Social media

The rising usages of social media in many nations has led to the emergence of citizens organizing protests through social media, sometimes called " Twitter Revolutions". The most notable of these social media led protests were parts Arab Spring uprisings, starting in 2010. In response to the use of social media in these protests, the Tunisian government began a hack of Tunisian citizens' Facebook accounts, and reports arose of accounts being deleted. Automated systems can be used to censor

posts, and therefore limit what citizens can say online. This most notably occurs in China, where social media posts are automatically censored depending on content. In 2013, Harvard political science professor Gary King led a study to determine what caused social media posts to be censored and found that posts mentioning the government were not more or less likely to be deleted if they were supportive or critical of the government. Posts mentioning collective action were more likely to be deleted than those that had not mentioned collective action. Currently, social media censorship appears primarily as a way to restrict Internet users' ability to organize protests. For the Chinese government, seeing citizens unhappy with local governance is beneficial as state and national leaders can replace unpopular officials. King and his researchers were able to predict when certain officials would be removed based on the number of unfavorable social media posts. Research has proved that criticism is tolerable on social media sites, therefore it is not censored unless it has a higher chance of collective action. It isn't important whether the criticism is supportive or unsupportive of the states' leaders, the main priority of censoring certain social media posts is to make sure that no big actions are being made due to something that was said on the internet. Posts that challenge the Party's political leading role in the Chinese government are more likely to be censored due to the challenges it poses to the Chinese Communist Party. In December 2022

On the platform TikTok, certain hashtags have been categorized by the platform's code and determines how viewers can or cannot interact with the content or hashtag specifically.

As TikTok guidelines are becoming more localized around the world, some experts believe that this could result in more censorship than before.


Video games

Since the early 1980s, advocates of video games have emphasized their use as an expressive medium, arguing for their protection under the laws governing freedom of speech and also as an educational tool. Detractors argue that video games are harmful and therefore should be subject to legislative oversight and restrictions. Many video games have certain elements removed or edited due to regional rating standards. For example, in the Japanese and PAL Versions of '' No More Heroes'', blood splatter and gore is removed from the gameplay. Decapitation scenes are implied, but not shown. Scenes of missing body parts after having been cut off, are replaced with the same scene, but showing the body parts fully intact.


Impact of surveillance

Surveillance and censorship are different. Surveillance can be performed without censorship, but it is harder to engage in censorship without some form of surveillance. Even when surveillance does not lead directly to censorship, the widespread knowledge or belief that a person, their computer, or their use of the Internet is under surveillance can have a "

" and lead to self-censorship.


Implementation

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 kindeven 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 "

statutory rape In common law jurisdictions, statutory rape is nonforcible sexual activity in which one of the individuals is below the age of consent (the age required to legally consent to the behavior). Although it usually refers to adults engaging in sexual ...
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).

Those who get caught are put on a blacklist called the watch list, and the person and the organization to which they belong are investigated in detail, which makes it easier to dismiss or arrest the "disturbing molecule".

Singapore

In the Republic of Singapore, Section 33 of the Films Act originally banned the making, distribution and exhibition of "party political films", at pain of a fine not exceeding $100,000 or to imprisonment for a term not exceeding 2 years. The Act further defines a "party political film" as any film or video :(a) which is an advertisement made by or on behalf of any political party in Singapore or any body whose objects relate wholly or mainly to politics in Singapore, or any branch of such party or body; or :(b) which is made by any person and directed towards any political end in Singapore In 2001, the short documentary called ''A Vision of Persistence'' on opposition politician J. B. Jeyaretnam was also banned for being a "party political film". The makers of the documentary, all lecturers at the Ngee Ann Polytechnic, later submitted written apologies and withdrew the documentary from being screened at the 2001 Singapore International Film Festival in April, having been told they could be charged in court.
