ABSTRACT
Radio played an even more important role after World War II. Radio receivers had become more widely available internationally, radio had become the principle information source to much of the world’s population during the war, and radio transmitters had become more accessible to dissident groups. Radio transmitters were also more widely available after the end of World War II, making them more accessible to opposition and underground groups such as the Greek National People’s Liberation Army (ELAS), a large, left-leaning guerrilla group that fought a hit-and-run war against the German occupation of Greece during World War II. The ELAS station, Free Greece Radio, demonstrated the importance of free radio in situations of conflict and civil war. Indeed, the United States responded to the conflict with the Truman Doctrine, a policy that justified military intervention in countries where the United States perceived its interests to be threatened.
