National Radio Day

National Radio Day is dedicated to a great invention and communications medium. A radio is a device for receiving radio broadcasts. These are transmitted by means of terrestrial transmission via electromagnetic waves or high-frequency electrical signals via the broadband cable. The received information is converted into sound. These days the only time most people pay attention to their radio is in their cars, but there was a time when it was the major means of communication in this country.
