Do you enjoy listening to the radio in the car? Or maybe to podcasts online?

Those exist because of the radio revolution in the 1920s. It is rather fascinating to see the rise of radio throughout the entire United States.

Telegraphs were already around for a while before radio began. People used telegraphs to send messages across far distances, courtesy of Morse code. This, of course, was a step up from sending letters with horsemen.

Another grand step up though, was through the work of Guglielmo Marconi. In 1895 he created and worked on a radio system that actually worked! It was a huge step forward in wireless communication (1920’s Radio).

You know AM and FM on modern day radio? Well Edwin Armstrong invented FM! Armstrong actually developed many different features of the radio, he also helped stabilize and amplify radio signals (History of American Radio).

On Nov.2nd, 1920, the first nationwide broadcast was made by KDKA station (1920’s Radio). Unfortunately, not many people had radios at the time so few people heard it. But after that broadcast became huge!

Sales skyrocketed and there were many different radio shows throughout the 1920s. Majority of American families had a radio by 1930 (Mortal Journey). But radio was a mess until the government stepped in and made the Radio Act of 1927 and the Federal Radio Commission to clean up the airwaves and regulate radio use (Radio Act of 1927).

Radio continues to influence people even in modern day.
