Am was the dominant method of broadcasting during the first eighty years of the 20th century and remains widely used into the 21st. Am radio, also known as amplitude modulation, is a type of radio broadcasting that uses amplitude modulation to transmit audio signals. Am broadcasting is a radio broadcasting technique that uses amplitude modulation to transmit sound on a radio carrier wave. Am radio began with the first, experimental broadcast in.
The earliest experimental am transmissions began in the early 1900s.
