Radio became popular in Germany during the 1930s; over 70 percent of households owned a receiver by 1939, more than any other country. By July 1933, radio station staffs were purged of leftists and others deemed undesirable.[450] Propaganda and speeches were typical radio fare immediately after the seizure of power, but as time went on Goebbels insisted that more music be played so that listeners would not turn to foreign broadcasters for entertainment.[451]
