You're confusing a transport mechanism with the platforms using it.
The point is I don't limit my consumption to news radio. There are other ways to get news.
There's a saying in Silicon Valley: "Eat your own dog food". In other words, you can't fully understand how your platform works, and how it's being used, unless you use it yourself.
I know how it works. I choose to use other sources. This is a purposeful decision.
Multiple sources. There are these people called "reporters". Admittedly an endangered species, they use various sources, including sometimes actually talking to other people, to find out what's going on.
You don't have to be employed as a reporter to serve as a source. By that I mean user-generated-content. People posting video of news taking place. That can be a source if you put several together for verification. Using the internet as a source gives you access to millions of reporters. We can't afford to hire millions of reporters.
I bet most of it is national in scope. There's still a role for local radio and TV news.
As I often say, I can cook my own food, yet I still like to eat out. So sure, there's a role for local. It's not a one or the other thing.
The change at KOA has to do with how people use radio. If a station does spot news, people will only listen for a short time. If a station has a talk show, they listen longer. The goal at KOA is to improve TSL. That's what we've seen at similar stations in other markets.
