Every year, people celebrate one of the greatest and most life-changing devices of modern society: radio. Radio is a device that has brought news and information into millions of homes and has been doing so for the better part of the last 100 years.

And that’s why August 20th is celebrated annually as National Radio Day. A day in which listeners, broadcasters, and radio stations can celebrate the tool that has brought so many people together.

The History Of National Radio Day

No one knows for certain when National Radio Day was celebrated, but it’s believed to go back to the 1990s. It’s not known why August 20th was chosen for the date of this holiday either.

The History Of The Radio

Even though Guglielmo Marconi is the one that’s usually credited with creating the first radio, the first radio transmission demonstration was actually performed by Nikolai Tesla in St.Louis, Missouri in 1893. Marconi receives the credit for this invention because he was issued the first wireless telegraphy patent in England and secured that patent in 1896.

The following year, Tesla filed for patents for his basic radio in the U.S. which was eventually granted in 1900. What places Marconi firmly in the history books, however, is not only his radio but that he also created the very first radio signal. He broadcast on December 12, 1901—sending the first radio signal across the Atlantic Ocean.

From 1900 to 1920, radio transmission was primarily used to contact ships that were out at sea. These messages were usually very primitive and consisted of Morse Code messages because, at this point, radio transmissions weren’t very clear.

During World War I, it became an important tool for sending and receiving messages to troops in the field without having to send a messenger. In 1920, the first commercial radio license was granted to the Westinghouse Company, and this lead to the creation of KDKA.

This made this station one of the first commercially licensed radio stations. KDKA would make its first broadcast on November 2, 1920. Radio sales spiked dramatically during the 1920s, so much so that by 1931, 40% of American homes owned a radio.

This rise in radio use would continue throughout the 1930s and by 1938, 80% of all American homes owned a radio. The first satellite radio broadcast would occur nearly 79 years later when Worldspace aired the first satellite radio broadcast in Africa on October 1, 1999.

By the end of 2012, the FCC estimated that there were more than 15,000 licensed radio stations located all throughout the United States.
