 In addition, media in the Eastern Bloc were organs of the state, completely reliant on and subservient to the government of the USSR with radio and television organisations being state-owned, while print media was usually owned by political organisations, mostly by the local party.While over 15 million Eastern Bloc residents migrated westward from 1945 to 1949, emigration was effectively halted in the early 1950s, with the Soviet approach to controlling national movement emulated by most of the rest of the Eastern Bloc.In the USSR, because of strict Soviet secrecy under Joseph Stalin, for many years after World War II, even the best informed foreigners did not effectively know about the operations of the Soviet economy.
