Soon after the division of Berlin in 1945, Russian influence and propaganda quickly expanded not only in Berlin but Eastern Germany and the rest of their satellite countries as well. For the Soviet Union ruled with a iron fist under Stalin and controlled all types of media thru lies and censorship, while self promoting communism ideology and values vs what they called the decadent West and free capitalism. So in the American zone of Berlin in 1946, Radio In the American Sector (RIAS) began broadcasting to counter the Soviet propaganda machine with their own communist Radio Berlin. The American signal was aimed mostly around Berlin and was especially crucial during the Berlin Airlift in 1948-49. About the same time in 1949 Radio Free Europe was formed and began broadcasting more toward helping European refugees with informative information and current events, which turned out was actually funded by the CIA until 1972. Then in 1953 Radio Liberation began broadcasting in Hesse, Germany but it's signal was aimed squarely at the Soviet Union population, to once again counter communist propaganda and censorship. These broadcasts continued for decades, as the Russians tried jamming the signal at the same time. Finally Radio Free Europe and the renamed Radio Liberty merged in 1976, while RIAS continued until 1993, with the demise of the Soviet Union. RFE/RL still continue today with the motto "Free Media In Unfree Societies" while expanding to more countries, as well with their own website. I seriously considered getting a European discharge while in the Air Force and working for Radio Free Europe in Münich, as I had some background in communications and spoke some German.

Strangely, the RFE was jammed but simultaneously the Soviets and the Poles produces advanced (but cheap) shortwave radios, double & triple conversion superhets that were able to defeat the jamming.
