He was wrong. His experiment was the very beginning of the electronic communications we use today. In recognition of his work, the unit of frequency of a radio wave, one cycle per second, is named the hertz.
STEVE EMBER: Radio waves became known to scientists as Hertzian Waves. But the experiment was still of no use until Guglielmo Marconi improved on the device that created Hertzian Waves. He began his experiments in Italy in eighteen ninety-four.
Guglielmo Marconi
Marconi was soon able to transmit sound across a distance of several kilometers. He tried to interest Italian government officials in his discovery, but they were not interested.
Marconi traveled to Britain. His invention was well received there. In eighteen ninety-seven, he established the Wireless Telegraph and Signal Company. The company opened the world’s first radio factory in Chelmsford, England in eighteen ninety-eight.

SHIRLEY GRIFFITH: Very quickly, people began sending and receiving radio messages across long distances using equipment made by Marconi’s company.
Ships at sea needed the device. Before Marconi’s invention, they had no communication until they arrived in port. With radio, ships could call for help if they had trouble. They could send and receive information.
All of Marconi’s radios communicated using Morse code. An expert with Morse code could send and receive thirty or forty words a minute. Marconi’s radio greatly increased the speed of communications.
