Radio's Beginnings

Radio technology has long been one of the most commonly used forms of mass communication that could connect people from around the world. Although its history ranges back far, its become adaptable through the years for it to still be used in the large variety of ways that it is today.

Those who work with radio in some capacity have a lot to be thankful for in German physicist Heinrich Hertz, whose work with radio waves helped him discover that it was possible for these radio waves to be transmitted wirelessly. This was the initial step towards radio technology.\

The history behind the exact creator of the radio is foggy. There had always been discussions and visions of some sort of radio communications system prior to the late 1800s, but no strides were seen until Nikola Tesla and Guglielmo Marconi made developments towards what would become known as the radio in the 1890s. There has been a debate over whether Marconi or Tesla is the true inventor of the radio.

The debate comes from the fact that Tesla showcased a type of wireless radio around the same time that Marconi produced his wireless telegraphy. Although Tesla’s feat occurred in 1893, and Marconi only received his patent in 1896, Marconi is widely seen today as the “father and inventor of the radio”. This is because Marconi received his patent before Tesla, and also because Marconi achieved the feat of being the first to broadcast radio signals across the Atlantic in 1901.

Nevertheless, radio has been able to advance through the years. After being used to communicate on and across waters for the military during World War I, radios were able to put into everyday homes during the 20s when broadcasting corporations started to sprout up. One of the most prominent examples is the Westinghouse Company, whose commercial radio license in 1920 for the KDKA station became the first of its kind to be authorized by the U.S. government. This became home to the very first radio broadcast that was licensed by the government in 1920. As a result, radio advertisements were created as radios became much more mainstream.

In the same year Lee de Forest invented AM, or amplitude-modulated, radio. This came about as a result of his invention of a “electromagnetic radiation” detector to make the radio waves signals stronger for broadcast. This helped spawn the creation of AM radio, thereby enabling the creation of many more radio stations to run at once. The widely known FM radio wasn’t invented for another 13 years, which was done by Edwin Howard Armstrong in 1933. This frequency-modulated radio could control the noise static seen in AM radio broadcasts much more easily. With less interference between multiple radio stations, this allowed for much more room for radio players on the airwaves.

Nowadays, we see radio everywhere, from our cars, to our phones, and laptops, which is interesting considering this is so different from its original use. At first glance, it seems like radio would be pushed to the side as online streaming of music has become so accessible through apps like Spotify, apple music, and tidal. Even though these apps have become so popular, radio features have still found a way to be implemented into them, with personalized radio stations for certain artists and genres within those apps. It’s impressive how radio has the ability to adapt to the technological advancements of today, and be implemented in both online and traditional radio stations and still see a wide range of use in both mediums. Personally, I see this as a good sign for the radio industry in future. Considering how adaptable radio is, I believe it will remain a mainstay in some capacity in the future as technology advances.
