speaker and  listener. That is the immediate aspect of radio. A 
private experience. The subliminal depths of radio are charged 
with the resonating echoes of tribal horns and antique drums. 
This is inherent in the very nature of this medium, with its 
power to turn the psyche and society into a single echo 
chamber. The resonating dimension of radio is unheeded by the 
script writers, with few exceptions. The famous Orson Welles 
broadcast about the invasion from Mars was a simple 
demonstration of the all-inclusive, completely involving scope of 
the auditory image of radio. It was Hitler who gave radio the 
Orson Welles treatment for real .

     That Hitler came into political existence at all is directly 
owing to radio and public-address systems. This is not to say 
that these media relayed his thoughts effectively to the 
German people. His thoughts were of very little consequence.
