My father grew up in Nazi-occupied Europe during World War II and would tell the story of how an official would come to his family’s home to modify their radio so they could not receive BBC broadcasts. Shortly after the official left, the family would open the radio box and fix the clumsy modifications that had been made so they could continue to receive outside news from a source not controlled by a fascist government.
In like fashion, during the Cold War, America broadcast its own messages behind the Iron Curtain through Voice of America. In response, some then-Communist countries tried to counter these broadcasts with jamming technologies. I hadn’t heard much about Voice of America since the fall of the Soviet Union, but it still exists as an independent federal agency. It has roughly a thousand employees and currently broadcasts the news in scores of languages around the world, drawing criticism from countries such as Russia and North Korea.
