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. In 1934, for example, there were 42 million radio receivers in the world. Only 100,000 of these were in Africa, 2 million in Asia, and 900,000 in Latin America. By 1949 there were 160 million receivers worldwide with 2 million in Africa, 8 million in Asia, and 6.5 million in Latin America. 1 Radio penetration had grown quickly during World War II because it was an efficient, safe, and inexpensive method for obtaining information, which could be easily assessed for accuracy by comparing the information provided by one station, such as the Overseas Service of the British Broadcasting Corporation (BBC), with that of another, such as Radio Moscow.
