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.
In 1980 I worked in local radio.
The playlist was set by corporate (or by a consultant). You could maybe change the order of the songs, but you were not allowed to add / subtract any songs.
By 1980 over 1/2 of the stations were "automated". Music was provided by a service, on Reel to Reel tape (played by Revox B77's).
Path to a radio job in 1980? A Third Class RadioTelephone License with Broadcast Endorsement.
An aside...
The automation machine at one station I worked at had 2047 programmable steps. (well, 2048, 0 was a step)
As a 16 year old, I could not fathom why it was not 2400. With 2400 steps, you could program each hour the exact same; not so with 2047.
Editing was a dream on the ASR33 teletype. Seems scissors and tape are very effective.
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.
Boston has a whole bunch of live and college ratio stations still.
Well, sort of. My radio presets back in the 2000s were 101.7 WFNX, 104.1 WBCN, 107.3 WAAF, 100.7 WZLX, and 92.9 WBOS. Of those stations, only WZLX remains.
The greats - in my opinion, WBCN and WFNX - are long off the air. They were powerhouses of culture, both local and national. WFNX was the first to play Nirvana's Nevermind; Bono of U2 once said that "...without BCN, we'd all be (expletive)'d, let's face it."
Oedipus, a well-known Boston DJ since the 70s (who got started at 88.1 WMBR, MIT's station) and program director at WBCN, said of it: "The Telecommunications Act of 1996 destroyed radio... Corporations were now allowed to own multiple stations in the same market and across the country. Stations were no longer programmed locally."
Meanwhile, WAAF went online-only in 2020. WBOS got delegated to an HD2 subchannel in 2004. Likewise, The Boston Globe picked up many of the radio personalities for the online-only RadioBDC, now Indie617, but that seemed dead by the mid-2010s. I hear the former WFNX DJs Henry Santoro and Julie Kramer may still have some limited presence on 89.7 WGBH.
I was recently happy to find Adam 12 (formerly of WFNX (formerly of WBCN)) still DJing on 105.7 WROR.
88.9 WERS (Emerson College's station) is doing a great job of carrying the helm of Boston music culture. Occasionally I'll also tune into 90.3 WZBC (Boston College's station), which is a more "traditional" and less "commercial" college radio station.
Just outside Boston are likewise some public and community stations with good programming - 88.3 WRPS (Rockland's public radio station) and 101.3 WFNX (Scituate's community station - love that they picked up the WFNX callsign!) are pretty good, if you're in range.
Counterpoint: I always found WERS to be a slightly broader interpretation of adult contemporary programming than the commercial stations.
My goto was WUMB, which is out of UMass Boston, and played a consistent format (folk and Americana, I guess?) throughout the day. Blues Hangover on WHRB (Harvard) was always worthwhile when I caught it.
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.
When I think about the glory days of radio, I think of American Graffiti.
I live in Austin and there's a pretty good station (I think it's actually a group of stations across Texas) called Sun Radio. I pretty much only listen in the car, but they are usually playing something I'm interested in.

At first I thought that was a complaint about electronic music and then I realised it means the station is automated with no humans. Could've been clearer.
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).
