Censorship

Censorship is the suppression or restriction of expression, publication, or access to information by an authority or other controlling party.

Prior restraint: A legal or administrative order that prevents expression before it is published or performed. It blocks publication in advance rather than punishing expression afterward.
Film censorship: The restriction or alteration of films by governments, regulators, or other authorities. Film censorship can shape both what audiences see and what filmmakers produce.
Freedom of speech: The principle that people should be able to express opinions without unjustified interference. It supplies a central rights-based standard for judging restrictions on expression.
Underground press: Publications produced and circulated outside official or mainstream channels, often under restrictive conditions. Censored writers and publishers have used clandestine distribution to reach audiences.
Digital rights: Human rights and civil liberties as they apply to digital technologies and online spaces. Digital rights frameworks address censorship across networks, platforms, and devices.
Licensing: A system requiring official permission to conduct an activity or distribute a work. Authorities can make publication or broadcasting conditional on prior approval.
Book censorship: The suppression, restriction, or removal of books from publication or access. Books show how censorship can target works long after their publication.
Freedom of the press: The principle that media should be able to publish news and opinion without undue interference. It focuses the censorship debate on journalism and public information.
Samizdat: The clandestine copying and circulation of banned literature in the Soviet Union and other Eastern Bloc states. It is a documented form of literary resistance to state censorship.
Net neutrality: The principle that internet service providers should treat online data without discriminatory favoritism or blocking. Unequal network treatment can restrict access without removing content from the web.
