(2009)ish
And a very American/mainstream-centric view of things. Radio (especially from the view of things in 2009) in more niche/underground circles was and in some regards still is a driving force of music curation and community in other parts of the world like the UK, parts of the EU and beyond.
Does radio have to be on the FM band? Do we count streaming like via YouTube, twitch and other platforms the same as Radio? I'd say yes. And in that regard, the spirit of radio and the format/feel the author recalls still very much exists.
Agree about YouTube and Twitch. Whatever personality you want, there's someone that fits it. You can pull up a recent stream or tune in and message them live if they're on. In some ways we're in the golden age of some of what the article was saying was lost, because pretty much anyone with a basic setup and a little bandwidth can start streaming and building an audience/brand. No need to get hired, no need to get a letter like in the story that says you might've been OK in a small town but you're not ready for the big leagues.
IMHO, FM radio stations, broadcasting on government-attributed radio frequencies, are very different - both in nature and in how they feel - from the user of a big corporation's service streaming from someone else's computers.
I have yet to see a streamer match what Click and Clack did on the radio..
I grew up in the UK in the 80's, and that entire generation received our music taste from BBC Radio 1. Literally the entire population of UK teens listened to that one station for ~20 years (though individuals would listen to different shows - John Peel's famous indie/punk/whatever show in the evenings was very different to the daytime mainstream stuff).
In Australia it was ABC's Triple J - similar story. Everyone tuned in to the annual top 100 tracks of the year.
That reach has not happened since with any media that I'm aware of. It was very unifying - we were all aware of the same songs, even if we didn't like the same songs. I can sing along to Duran Duran even though I was very scathing of them at the time, in part because I was force-fed Duran Duran every day on the radio.
