You're right, and that's what Wagoner would see if he spent time with them. He mentions Woody and all those existing shows, but he doesn't mention Joe Rogan or those who command massive audiences on TikTok or other social media. His head is so oriented around traditional media that he doesn't know where the real audience is. The reason they're there is because they built their audience from scratch.
I'll tell a little story from nearly 60 years ago.
I was in Ecuador, and had the three highest rated station in a market of over 40 total fulltime local stations.
There was no FM. I decided FM would be a good way to link my studios with my AM transmitters and built 3 lower power FMs. I also got a nice Philips console radio-record player.
Gee, the FMs sounded so much better than the AMs they were serving. Maybe I need to have some of those.
This was around 1966, when FM was still struggling in the U.S., so I did not have a real model to emulate. So I built the first independent FM between Costa Rica and Peru. It had a modified instrumental music format with a vocal in the second spot of every three song sets; the vocals were soft ballads and lots of Latin American folk music.
We set a commercial limit of one 20" spot every 10 minutes, or 2 minutes total an hour. No hard jingles, no hard sell.
What I did had no ´precedent, but it did not use the past as a way to model the future. It broke every rule on commercial time, content, and even the band.
When I launched the first of those stations, soon after there was a meeting of our local Ecuadorian equivalent of the National Association of Broadcasters. One member, a competitor, spoke and asked why the association was allowing a member to "create" a new band when one was not needed and where doing this would confuse listeners. They got applause from many of the other broadcasters.
I said, "Do you have a spare S/ 500,000? I'm spending that on each station and you are welcome to do the same. The band is empty." No response.
All the veteran radio people, including a lot of my staff, said that it would not work. They thought that the FM was my eccentric hobby and that I was wasting time. By the end of the first year, the station was profitable. By the end of the second one, it had a higher operating margin than any of my AMs.
A long story, but it brings me to the question of "what innovative approach to new media are existing radio broadcasters taking?" (It's so quiet I can hear the crickets chirping...)
