Censorship in Communist Poland was primarily performed by the Polish Main Office of Control of Press, Publications and Shows [pl] (Główny Urząd Kontroli Prasy, Publikacji i Widowisk), a governmental institution created in 1946 by the pro-Soviet Provisional Government of National Unity with Stalin's approval and backing, and renamed in 1981 as the Główny Urząd Kontroli Publikacji i Widowisk (GUKPiW). The bureau was liquidated after the fall of communism in Poland, in April 1990.[

In Poland under communist rule, censorship was institutionalised through the activity of the Main Office for the Control of Press, Publications and Shows (Główny Urząd Kontroli Prasy, Publikacji i Widowisk) which operated with an elaborate set of instructions and prohibitions, as revealed in the erstwhile émigré publication of the Black Book of Censorship in the Polish People’s Republic (Czarna księga cenzury PRL). - https://notesfrompoland.com/2020/06/10/how-rock-music-became...
