Being that streaming in general didn't become a massive deal until after 2010 (it had some adherents before then, but didn't become the increasingly dominant audio entertainment medium until after 2012 or so, at least according to the RIAA), I personally don't think radio dropped the ball.
I hope you're right. I don't know that the data support that conclusion, though. On the bright side, radio still reaches more than 80% of the population at least once-a-week. On the down side, people spend less time with it than ever before. Listening is down roughly 75% from where it was 20 years ago.
I don't think that the streaming audio marketplace will really come into its own until the 2030's, when FMs may start to pull the plug. A lot can happen in 15 years. And as BigA has said before concerning this subject, consumers like the cost of free, and FM radio is free, and always will be. Streaming? perhaps not. Especially if digital royalties go up again.
All the time listening to radio that has gone away went somewhere. Most of it probably wasn't to video, and none of it went to the newspaper. Getting the information is difficult for the general public as most of those companies either don't release their numbers or bury them deep in their financials, but streaming would seem to be where the bulk of that listening has gone. I don't know that FM will pull the plug in our lifetime, but I do agree that there will always be a market for radio in some form or another. When it comes to streaming, even if you don't pay to listen, you're paying for your internet and your data plan. I get that reminder every month as my cable bill is now in excess of $250, and my cell phone adds about $100 to that. Most people, though, no longer view those as discretionary expenses. (Thanks, by the way. You just reminded me I need to return the fiber internet company's call from a few days ago; switching to it from the cable company should save me at least $100/month!)
RE: The record labels mistake: One could argue that their mistake was going along with the 99 cent MP3 single, being that their revenues nosedived after that. The 99 cent MP3 single killed the album, and by 2019 that cut their revenues roughly 40% from where they were in 1999. Of course, after Napster, the writing was on the wall. MP3's and file sharing of some sort was here to stay, and the 99 cent single was designed to counter that (and make Apple a lot of money).
Problem was people didn't want to pay north of $10 to buy an album when they only wanted one song. The labels should've figured that out and gotten in front of the situation before the audio pirates arrived. The pirates probably would've arrived anyway, but giving the consumers what they wanted and being able to control that was always going to work better than trying to ram overpriced media down their throats. The only viable solutions were to let consumers buy a la carte, provide better songs on each album, or make the albums more of an entertaining and interactive experience when put into a CD-ROM drive. The labels chose to stay the course and forge ahead attempting to make the consumer bend to their will. It didn't work.
