I googled your interesting HN username and best as I could tell it refers to what was a satellite radio show.
Satellite radio probably contributed to the demise of AM radio in countries where its available. It offers the benefits of AM (range) without the major downside (quality) with both being infrastructure heavy.
AM RAdio also has the advantage of numerous AM recievers widely available. Good for mass communication over high population areas - particully in times of emergency. AM uses less complex systems to transmitt and recieve compared to other modulation methods, example FM. Transmission via internet tends to be much more fragile and breakable. I could easily build a simple (limited) radio, Crystal set in about a hour that would work in strong AM signal areas like in most cities or up to 50 milies away. AM radio also has range measure in hundreds of miles, much greater at night... Removing AM radios from Cars is alll about savig a few $ , probably like $20 for can makers.
You're making an apples to oranges comparison. If you can send a signal via a radio between continents, one can send a podcast using that signal with zero infrastructure between the sender and the receiver.
AM radio, like other frequencies in the low HF spectrum, travel using ground waves then ionospheric refraction during night which can let the receiver pick stations several thousands of Km away. FM and generally VHF frequencies require mostly the transmitter to be in line of sight. When a disaster occur, you can pick AM radio emergency transmission from behind a mountain or from much far away than a FM station. This allows the elimination of any dependency on repeaters which are a weak link, especially in less than free countries that censor radio transmissions, whose listener couldn't pick a station from another country if it needed a repeater in theirs. AM is for freedom, not for music.
In an emergency situation, you can build a CW transmitter off parts reclaimed from a broken PC power supply, connect a diy antenna made with a simple wire and be picked up from another country; a walkie talkie will stop at the 1st hill.
AM is critical for emergency scenarios. When Hurricane Maria hit Puerto Rico, all our infrastructure was completely devastated.
The only way to receive news or bulletins for weeks was just one remaining AM radio station that kept broadcasting even as the storm hit and their building began to flood.
>why is the medium relevant at all? what does radio do that a podcast cant
Deliver the news to you anywhere and everywhere with a receiver that can be built from scavenged garbage. Terrestrial absolutely still has a place, and will most likely outlive the internet.
Also, radio broadcasts a signal and is completely agnostic to who picks up the signal and listens. IOW, you can listen to radio without anyone/anything tracking what you. Not being tracked and data-collected for everything is still important to some of us.
That’s right, nothing. “Movie theater attendance is well below pre-pandemic levels, with global cinema admissions hovering at roughly 64% of their historical peaks”
Yes, lower sales performance means we should eliminate all movie theaters so our children never have the opportunity to experience them. Profits are the only factor.
You’re right that experiencing a movie individually on a phone screen is the ideal medium.
"It, for many, many years, was a part, and I would argue not a small part, of what held the country together."
Indeed! A shared news source with known, manageable bias (don't rock the boat, bite the hands, and ostensibly just deliver events of the times as they happen).
A common, shared reality is a good thing for unity.
With everyone hating on AM radio (HN included) and thinking the EV automakers were right for eliminating it from cars, this was the inevitable result.
People hate on AM radio? I love it. Nothing like listening to baseball over AM.

A podcast requires thousands of pieces of fragile infrastructure between the sender and receiver.
Radio can send signals between continents with zero infrastructure between the sender and receiver.

A podcast is an audio program delivered over the internet, which requires quite a bit of intermediary infrastructure regardless of the layer 1 medium.
When you deliver the raw audio over RF, it is called a radio program, which is what CBS has stopped broadcasting.
The throughput and bandwidth necessary for "podcasting" is many times greater than simple radio
Not to mention the complexity of the hardware required.

Radio has an almost orthogonally inverse set of failure modes than internet streaming.
Internet.connection (∴ tracking) not required
AM signals have a far reach and are often used for road and emergency updates.
Emergency broadcast is a big one, as well as location-specific information like road conditions.
They live in different layers of "medium". This is like asking "What does piping do that juice doesn't?", they're not mutually exclusive.
Work without internet infrastructure
AM is critical for emergency scenarios. When Hurricane Maria hit Puerto Rico, all our infrastructure was completely devastated.
The only way to receive news or bulletins for weeks was just one remaining AM radio station that kept broadcasting even as the storm hit and their building began to flood.
It's not just the medium. Streaming from the internet is a totally different product than radio. There's no reason we can't have both.

what does a movie theater screen do that a phone screen can’t?
That’s right, nothing. “Movie theater attendance is well below pre-pandemic levels, with global cinema admissions hovering at roughly 64% of their historical peaks”
Yes, lower sales performance means we should eliminate all movie theaters so our children never have the opportunity to experience them. Profits are the only factor.
You’re right that experiencing a movie individually on a phone screen is the ideal medium.
I didn’t say any of those three things.
And I didn’t say “nothing.”
Count how many subscriptions are between you and that podcast.
It's literally absurdity that you even wrote this at all.
News Roundup podcasts are still up, for those who never heard them. https://podcasts.apple.com/us/podcast/cbs-news-roundup/id172...
