According to Nielsen.com, almost half a billion people still listen to radio everyday as did 50 years ago. Radio is by far the most consistent audio only format existing today. I know of radio personalities that have been on air for 30+ years. Kemal Amin “Casey” Kasem was an American radio personality most famous for American Top 40 from 1970 until his retirement in 2009. Kurt “Big Boy” Alexander has been on air since 1997 and even the switch from analog to digital didn’t stop him. The list goes on. And what’s for certain is that, people love radio. Talk shows, news, and of course music.
Radio waves were first identified and studied by German physicist Heinrich Hertz in 1886. The first practical radio transmitters and receivers were developed around 1895 by Italian Guglielmo Marconi, and radio began to be used commercially around 1900. Radio is the technology of signaling and communicating using radio waves.
Note: Waves are electromagnetic waves of frequency between 30 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter, connected to an antenna which radiates (broadcast) the waves, and received by a radio receiver connected to another antenna.
To prevent interference between users, the emission of radio waves is strictly regulated by law, coordinated by an international body called the International Telecommunications Union (ITU), which allocates frequency bands in the radio spectrum for different uses.
We all know that technology changes the way we live and communicate. Some for good and for others, not so good. Naturally we are adapters and survivalist, yet radio remains heavily a part of our daily routine.
There are many new forms of audio only streaming that exist. (Visit my previous post Good Ways To Discover New Music listing a few of my favorites.) Some came and went, unlike radio. Of course most, if not all, are now digitally transmitted. I believe the original technology (analog live) changed our lives and the new technology (digital on demand) is steadfast at attracting and keeping listeners (subscribers) by giving control to the user and simplifying their experience.
Podcasting is one. Though in my opinion, the live aspect is what makes radio so intriguing. The way the broadcast is segmented and the mysticism of the next song, news story or interview, keeps you there even through commercials. And you gotta love the iconic disc jockey’s who get us through each day, year after year. I still listen to it and most people, they can’t live without their radio. Do you still listen to radio?
