In his day everyone stopped to listen to the President of the United States give one of his famous “fireside chats” on the Radio. Of course, this was before television had come into use. Rush Limbaugh hadn’t been invented yet, either.
Presidential radio addresses do not get the same degree of public attention as they did in Roosevelt’s day. Fox News wouldn’t allow it.
A couple of years ago the President was a Republican. His radio programs didn’t get much attention, either. FDR’s ghost wouldn’t allow it.
Or maybe I’m giving ascribing too much power to Fox and FDR. Rock hadn’t been invented then, either.
