I think it's a bit more than simply radio being off Carr's radar. This administration (to oversimplify it a bit) views independent federal agencies two ways. They are either there to be exterminated (like Education and the CFPB) or exploited by "weaponizing" them to do the whims of the President and his handlers. They see the FCC as useful because they can employ it to strong-arm broadcasters into becoming de facto propaganda outlets or at the very least allow the government to police content. Allowing mergers to where the Ellisons or the Bezos or the Murdochs of the world can own as much of the media landscape as possible is about making money for those folks, of course, but it is also about control On the surface its outlets like Fox getting the man to call into their morning show so they can gush "Mr. President we're so happy to have you on this morning" and fawn over him, but on a deeper level it's about controlling enough of the media to "flood the zone" with friendly coverage...literally the whole idea behind the creation of Fox News in the wake of Watergate.FCC watchers have been complaining about that since the 70s. There's been a systematic replacement of engineering people with lawyers. I wonder how many people at the FCC know anything at all about radio. Most of what Carr focuses on with regards to broadcasting is TV. That could be because radio is completely off his radar. That's not a problem unique to this administration. It gets back to what I said about the communications act. Al Gore was the one who called for the rewrite in the 90s. He said it was obsolete. He wasn't wrong. It may be time to revisit it. The problem is that the potential fixes will open up a huge hornet's nest. Just like they did in the 90s. My view is the only role for the FCC in broadcasting is spectrum management. Everything else gets deleted.
That took years, but it worked. Fox News is far and away the "winner" in the cable news wars, and they obviously want to expand that level of success and they see the FCC as very useful in accomplishing that goal. And that's kinda terrifying. The Founders - correctly - saw an independent press as a critical check on the power of government, and while they couldn't imagine radio and television, I think they'd agree that the "news media" we have now should not be turned into a tool of the government.
