STEVE EMBER: On December twenty-fourth, nineteen-oh-six, radio operators on ships in the Atlantic Ocean near the American coast began hearing strange things. At first it was violin music. Then they heard a human voice. The voice said “Have a Merry Christmas.”
That voice belonged to a man named Reginald Fessenden. He had been working on producing a device that could transmit the human voice or music using radio. He decided to try it for the first time on December twenty-fourth. It was the first time a human voice had been heard on radio.
SHIRLEY GRIFFITH: Improvements in radio technology now came more quickly. Large companies became interested. Broadcasting equipment and radio receivers were improved.
Fourteen years after Reginald Fessenden’s voice was heard by radio operators at sea, the first real radio broadcast was transmitted. It came from the city of Pittsburgh, Pennsylvania.
The radio program was transmitted on radio station KDKA on the evening of November second, nineteen twenty. The man speaking on the radio was Leo Rosenberg. He was announcing the early results of the presidential election between James Cox and Warren Harding.
STEVE EMBER: Those first KDKA broadcasts led to the success of the radio industry. People began buying the first radios. Other companies decided radio could make a profit. Only four years after the first KDKA broadcast, there were six hundred radio stations in the United States. Radio stations also began to broadcast in other countries.
