We all know the lyrics: “video killed the radio star.” But even today, that is not true. The radio is still the top-reach medium in the U.S., with 92 percent of Americans being reached every week.
This is followed by TV reaching 87 percent of the U.S. population and smartphones reaching 81 percent.
Radio has remained a staple to our media consumption. However, it didn’t start off as a means of entertainment.

The Discovery of Radio Waves
Radio waves have the longest wavelengths on the electromagnetic spectrum.
In the late 1880s, Heinrich Hertz proved the existence of radio waves. He essentially attached spark gaps at the end of an induction coil and the receiving end of an antenna. The waves created were picked up by the antenna, and sparks would jump the gap between the two.
The Wireless Telegraph
Approximately a decade later, Guglielmo Marconi used the knowledge of radio waves to create the first wireless telegraph. He successfully sent a message from England to Newfoundland—across the entire Atlantic Ocean.
The wireless telegraph worked by tapping Morse code onto a telegraph key, creating a message of electrical pulses that could get picked up at a certain frequency.
Marconi won a Nobel Prize for his work on wireless communication. His work kickstarted the way in which we use the radio today, which began to sell commercially in 1900.
The early uses for the wireless telegraph generally consisted of military communications.
The History of the Radio as We Know It Today
It wasn’t until 1914 that a Canadian by the name of Reginald Fessenden discovered a broadcast wave strong enough to transmit voices and music. He worked with General Electric to build alternators that could sustain a wave as powerful as this across thousands of miles.
By 1919, General Electric bought Marconi’s wireless telegraph resources in order to form the Radio Corporation of America.
It was the perfect time for an application of this sort to be invented, as news of World War I could be dispensed much more efficiently. It became a necessity to stay up-to-date and entertained.
With this invention, the world became unified — for better or worse. Information could get presented immediately, which changed our society’s way of life.
Political leaders influenced public opinion with this device. Both Adolf Hitler and MLK Jr. presented radical ideas to the masses—sparking huge points of history.
The most common use of radio is for entertainment in the car. People pursue careers out of this line of work. We can listen to music, advertise our businesses, and hear the news 24/7.
The Radio Industry
We’ve come a long way since radio waves were first discovered. The history of the radio contains good and bad moments, but we aim to make more good out of this fine invention.
