GM highlights car audio's switch to phone integration
Ever since Nicola Tesla first demonstrated radio to an audience in 1893 the device was destined for use in the automobile. By 1930 the radio had evolved enough that the Galvin brothers first placed one into a car with commercial success. Radio became not only the delivery system for baseball games, music and programs, it was one of the main forms of communication in the United states. Presidents used regularly scheduled radio programs to deliver news and politics to Americans and through the Second World War was the main way Americans learned what happening in their world.
