Censorship in the Soviet Union was pervasive and strictly enforced. Censorship was performed in two main directions: State secrets were handled by the General Directorate for the Protection of State Secrets in the Press (also known as Glavlit), which was in charge of censoring all publications and broadcasting for state secrets Censorship, in accordance with the official ideology and politics of the Communist Party was performed by several organizations: Goskomizdat censored all printed matter: fiction, poetry, etc. Goskino, in charge of cinema Gosteleradio, in charge of radio and television broadcasting The First Department in many agencies and institutions, such as the State Statistical Committee (Goskomstat), was responsible for assuring that state secrets and other sensitive information only reached authorized hands. Destruction of printed matter The Soviet government implemented mass destruction of pre-revolutionary and foreign books and journals from libraries.

From 1932 until 1952, the promulgation of socialist realism was the target of Glavlit in bowdlerizing works of print, while anti-Westernization and nationalism were common tropes for that goal. To limit peasant revolts over collectivization, themes involving shortages of food were expunged.
