Good radio died in the mid 80s.
Most people today can hardly remember when radio was curated live. Perhaps if you were near a small station you might have had the experience. Most major markets were completely corporate by the early 90s.
I know, my first career pick was radio, and by the time I was in college at a college radio station in the late 90s. That career path was dead unless I wanted to be in marketing or sales, which I had no interest in.
Little factoid about my username, it was my pirate station call letters from when I was running my own small station with a hand built FM transmitter in the 90s.
Boston has a whole bunch of live and college ratio stations still.
I'm reminded of Adrienne Barbeau in The Fog with her late night radio station in a lighthouse, or Lily Tomlin in Prairie Home Companion saying "Now radio's just a bunch of people yelling at each other and computers playing music". Although I was pleasantly surprised when I saw a GenZ girl doing something I had forgotten about: channel surfing.
You don't necessarily need to be near a small station these days, college stations can stream online. I listen to WXPN (UPenn) that way regularly: https://xpn.org/ (player at top of the page).
It died mid 80s for me too. That was when the monoculture, where everyone was listening to the same thing, just disappeared. I was just a kid so I never knew what happened. All I knew was that when I was itty bitty, I could turn the dial and find mostly the same stuff everywhere. Mid 80s onwards and it was all fractured. That fracturing continued to the point where it’s like there’s a genre and a band for every taste…which is cool, but now we don’t have a broadly shared cultural experience anymore. Ditto for television. Basically, the scarcity is gone. On the one hand, cool, but on the other, society weirdly suffers.
