The radio has been part of our lives for at least a century now. In a similar way that millennials got so hooked with TV series and the other perks of the online world, previous generations enjoyed listening to programs and music on the radio. However, there are little known facts about the radio. So, here is a list of some interesting facts about the radio:
- Guglielmo Marconi- He was known as “the father of the radio”. However, he was only able to successfully transmit radio signals, no voice transmission. It was only in the early 1900s that a successful voice transmission experiment took place.
- Nikola Tesla- This genius already had a basic radio design in 1892, but Marconi claimed the first radio patent. Although Tesla tried to prove that he created the first radio, it was only in 1943 that he was finally given credit after Marconi’s patents were considered invalid.
- Amplitude Modulation (AM)- The first radio broadcastings were done through the amplitude modulation (AM) radio waves. The antennas that transmit a wavelength the size of a football field consumed up to as much as 50,000 watts.
- 15-second long commercials- You might haven’t noticed that majority of the radio commercials are just 15 seconds long. This has been proven effective to reach ample amount of audience.
- KKDA- This is considered to be first the commercial radio station in the world which is located in Pittsburgh, Pennsylvania. The station aired the first commercial in 1920.
- 1939- This was the year that FM Radio first made its appearance.
- 44,000- This is the number of active radio stations across the globe, according to a UNESCO report.
