I think that you should look into the history of talk radio, or maybe just radio in general. Then maybe a history of American journalism, from Robert McCormick's Chicago Tribune back to the the party newspapers set up in the first years of the republic.
Yepp, same message different medium. Having someone in your family who “listens to talk radio” was the “they went down the far right YouTube rabbit hole” of old.
I mean the big names in talk radio are still clucking if you want to listen to them today.
