Propaganda

Link for wikipedia page

Russian revolutionaries of the 19th and 20th centuries distinguished two different aspects covered by the English term propaganda. Their terminology included two terms: Russian: агитация (agitatsiya), or agitation, and Russian: пропаганда, or propaganda, see agitprop (agitprop is not, however, limited to the Soviet Union, as it was considered, before the October Revolution, to be one of the fundamental activity of any Marxist activist; this importance of agit-prop in Marxist theory may also be observed today in Trotskyist circles, who insist on the importance of leaflet distribution).

Soviet propaganda meant dissemination of revolutionary ideas, teachings of Marxism, and theoretical and practical knowledge of Marxist economics, while agitation meant forming favorable public opinion and stirring up political unrest. These activities did not carry negative connotations (as they usually do in English) and were encouraged. Expanding dimensions of state propaganda, the Bolsheviks actively used transportation such as trains, aircraft and other means.

Josef Stalin's regime built the largest fixed-wing aircraft of the 1930s, Tupolev ANT-20, exclusively for this purpose. Named after the famous Soviet writer Maxim Gorky who had recently returned from fascist Italy, it was equipped with a powerful radio set called "Voice from the sky", printing and leaflet-dropping machinery, radiostations, photographic laboratory, film projector with sound for showing movies in flight, library, etc. The aircraft could be disassembled and transported by railroad if needed. The giant aircraft set a number of world records.
