I think what people are thinking of is the brief moment in the early 70s when FM radio was a bit more adventurous and experimental. That lasted a very short time, and really wasn't very successful. Then a bunch of consultants came in to make rock radio more commercially viable. It worked. Until the end of the 80s. That's when the music became more individual and no longer fit into formats.
I was around during part of that era, but I was too young to have any interest in radio. I do know, however, that consolidation didn't kill that the 70's era of radio. Like you mention, that model of radio wasn't very successful, and, as more people had access to FM in more places, those stations started trying to appeal to the masses.
If that many stations weren't "profitable" how did they stay on the air? I maintain a lot of that was because of independent owners where they didn't show "profit" because they paid a livable salary to the party that owned them. It's all in how it was documented. If they truly were failing to that degree, there'd have been far fewer stations long before now.
While some of those operations may have engaged in creative accounting, keep in mind that radio stations were often loss leaders or served another purpose for the people and companies who owned them. I know we've talked in other threads about insurance companies, car dealers, and oil companies owning radio stations. Radio was merely one arm of the business. As you use a handle that came from WKRP, you might remember the episode when WKRP toyed with changing formats to easy listening. The staff couldn't believe it because the station was finally making money, and either Arthur or his mother explained that Carlson Industries had its hands in multiple businesses, and WKRP existed specifically to lose money so it could be written off on taxes. While that was probably a bit of a characature, radio was frequently allowed to lose money if it added value elsewhere in the company.
Don't forget, also, the sunk cost fallacy. Some of the people who ran radio stations had plenty of money and were able and willing to hold on until they could recoup their losses. Selling or signing the station off simply meant the money was lost.
People can trash the system in Canada, the UK, Europe. But at least they didn't over license the stations. Call it anti-capitalism? The small businesses and "corporate" broadcasters did very well under those systems and kept a lot of people employed.
Actually, they didn't, at least in Canada. In 1990, roughly half of US commercial stations were losing money. In Canada, it was more than 60%.
They also had regulations where, instead of letting SoundExchange neutralize a ton of potential growth in streaming, they have systems where you can be an "indie" or small station and still NOT lose money streaming your signal! In the UK and Europe, they managed DAB transition so nearly 50 percent of listening now is on DAB, which is linear professional radio! And they also provided a much more straightforward community radio service. Did you know in NZ, you can buy an approved transmitter and serve your neighborhood on a specific frequency without a complicated engineering process? Did you know at least two of those brands started in people's spare rooms became national brands? Sounds to me like a culture that supports entrepreneurs.
I have my share of problems with the royalty structure of streaming. I'll admit it's been 15-20 years, but, last I'd heard, the UK's royalty structure for streaming was actually more oppressive than the system here. Canada's, while cheaper than here and in the UK, wasn't necessarily cheap either, and that doesn't include the royalty Canadian stations pay for the over-the-air product. Again, I don't follow the system there regularly, but I seem to remember it being in the 6-8% range in 2010. The average profit margin of the radio industry in the US isn't even that high.
I have never thought the US is as business friendly or as entrepreneurial as it likes to tell itself and the rest of the world either. That's a discussion for another day, though.
The continued mentality of too big to fail. I say let them. Let stations go off. Let idealistic people get in for less. None of these companies lobbying for loosening of restrictions were denied the chance to do the things that could have put them in a better position. Let the values fall, the new people try, and maybe they'll fail too. But at least we didn't just sign off the last of what's supposed to be a public interest, the broadcast spectrum, go to prop up someone's executive compensation plan (to offload it to someone else, also too big to fail.)
If you want to let stations go off, that would be one way to solve the problem of too many stations. I can respect that. The audience, on the other hand, has already spoken and has made clear it likes more choice. Don't forget, also, that the way new licenses are awarded now is by auction. Idealistic people aren't likely to get in at all, let alone for less.
Let's put a stop to the pretense and the nonsense. Maybe out of the ashes will rise some innovators. In the meantime, I'll be listening to the ones who, today, are actually making it work by doing all the things that are supposedly out of date and no one cares about because TikTok, or whatever. Here in the real world.
The innovators aren't going to be using old technology to innovate. Maybe one or two would try it, but, by definition, innovators are looking forward, not backward. Right now, there's nothing stopping anyone who wants a radio station from starting one on Live 365 for an affordable fee.
