Each year on August 20th, National Radio Day recognizes the great invention of the radio. Celebrate the news, information, music, and stories carried across the airwaves.

Several inventors had a part in the invention of the radio in the late 1800s. Amazingly, not just one person can be credited with its beginning. Instead, each component developed through invention and discovery. As these technologies converged, the radio came to life.

THE CONTRIBUTORS

In the paragraphs that follow, a noted international effort contributed to the conception of the radio. In Germany, Heinrich Hertz’s research proved electricity could be transmitted wirelessly. Elsewhere, the prolific inventor patented multiple inventions and provided the radio with the Tesla coil. Born in Croatia, Tesla also contributed many patents involving alternating current. Not only did Tesla make the radio possible, but he also advanced the science and production of numerous other inventions. However, when it comes to the first commercially available wireless, Italian, Guglielmo Marconi receives the honor.

Entertainment and music didn’t always fill the airwaves. In fact, the radio’s first function was much more practical. First, the wireless radio served the military. The radio also provided a regular public service role. Much like the dits and dots of a telegram, the wireless transmitted information. Aboard the Titanic at the time of its sinking, a Marconi wireless broadcast the ship’s distress signal. In 1906, the first radio broadcast of voice and music purely for entertainment purposes aired. Reginald Fessenden transmitted the program from Brant Rock, MA for the general public to hear. The Canadian born scientist would go on to many more successes in his lifetime.  

An American contributor to the radio, Lee de Forest invented the Audion vacuum. This invention made live broadcasting possible. Born in Iowa in 1873, de Forest would become the chief scientist for the first U.S. radio firm, American Wireless Telephone, and Telegraph.    

BROADCASTS

The 1920s brought the first broadcast stations to the forefront. Around the world, listeners tuned in for news and world events for the first time. Other radio facts include:

  • Radio ownership grew. In 1931, two out of five homes owned a radio. By 1938, four out of five owned a radio.  
  • According to FCC statistics, at the end of 2012, more than 15,000 licensed broadcast radio stations were operating in the U.S.
  • On October 1, 1999, the first satellite radio broadcast occurred. Worldspace aired the broadcast in Africa.
