Radio also was your connection to your city and the city's youth communities. Which are now fragmented, subcultures, and frequently dominated by someone trying to make the scene into their living. As far as I know, nothing has filled that community void, and community itself is dying.
Local community is probably irreparably damaged. But I was a kid with niche interests and I didn't start to find my people until the Internet entered my life in 1989.
I was a 'classic 70's latch key kid', that somehow discovered underground radio during elementary. Starting with "Dr. Demento" somewhere in my youth, by 6th grade it was "no commercial potential radio", mimeographed fanzines from everywhere on earth kids liked music + comics, and the punk rock + art music underground with shows at Unitarian Churches and abandoned buildings.
You do realize that the radio stations and everyone who worked at them used their radio "scene" as a way to make a living, right?
The scale of a radio station, versus the scale of one promoter today is night and day. The ownership of distribution of information is a curious thing; when it was more controlled we had community, and when that control relaxed the previous "controllers" did everything in their power to pollute the new communications channels with bad actors, essentially destroying the potential for community to form again. If someone cannot control the entire apparatus, those that cannot make sure the medium is non-commercially useful. Part of their protection of their medium, no others can be allowed to become viable as a replacement.
