I never got into the habit of listening to "the radio", in the sense of an AM or FM station broadcasting over the air on some frequency in a general metropolitan area. I remember listening to the radio stations my parents liked to listen to in the car as a kid. But by the time I was old enough to drive myself, I had already owned an mp3 player for a while, and if I wanted to listen to music in (my parents') car I could plug it into a cassette deck adapter - it's not like any local radio station near me was gonna play the Final Fantasy VII OST or a mix that went from Eve 6 to Jethro Tull to Blind Guardian to an bluegrass version of the Bubble Bobble theme I found on OCRemix. Plus, no commercials.

And if I wasn't actively driving a car at the moment, I probably had something I could be doing with a computer, perhaps involving a YouTube video, or just listening to my own extremely idiosyncratic music choices, that was more interesting than a local radio station, even if I technically owned some kind of device that could receive an FM signal.

Soon enough I had a smartphone and then a smartphone with a mobile internet connection whose cap was generous enough that I didn't need to think hard about how I was using it. And it turns out that having the entire internet available to me on a handheld device subsumes everything I might get out of listening to a radio station - including the modality of listening to audio while I'm doing something else, which might well come from an internet radio station anywhere in the world.

It occurs to me when I listen to a podcast while I'm working out at the gym or driving a car today (via my phone) that the actual auditory experience of this isn't drastically different than how people were consuming talk radio shows decades ago (down the fact that many of them have ads). The techniques for speaking in an engaging way to an audience, or having an engaging conversation between multiple people, are still valid; many podcasts I listen to address listener messages on the program, just like a weekly radio show might do - some even try to replicate the experience of a listener calling in live on a phone.

The business models that work today are of course drastically different than the ones that worked on radio decades ago, and the fact that audience isn't at all limited by physical location means that the sorts of audio content that gets streamed over the internet today are systematically different from what would've been the case on a radio show. I think this is mostly for the better though - more variety, more democratic access to the medium, and no FCC to regulate what you can and cannot legally say on regulated radio spectrum.

As far as I'm concerned, everything that's good about the content of AM/FM radio has been replicated on the general internet, and I have no particular reason to care if the radio signal carrying it to my ears comes from a licensed FM station or the 5G connection from my phone to a cell phone tower.
