Interestingly multicast is used extensively by exchanges to distribute trading data to participants. I think it's the primary commercial usage outside of some IoT things.

I'm not sure I understand the point. For small home networks, there is no bandwidth difference between this and streaming solutions like Jellyfin. Yes, this was a cool technology, and if some large provider like AT&T wanted to use this to broadcast channels to everyone at once it would've made more sense than streaming... but even for that use case the world has moved on. Does anyone watch scheduled television anymore except local news and sportsball?

AT&T does (or did) use multicast for cable tv replacement...

To demonstrate...multicast TV distribution on a home network?

Jellyfin and multicast TV distribution are not the same things, though. They're very different.

Some other things that are very different include: The temperature of Lake Superior, my mother's collection of weird ceramic houses that light up, and red herring.

Multicast has ceased to be a cool technology? That's hot.

They do that.

> it would've made more sense than streaming

They do that, as well.

All of it? Uniformly?

We should not use multicast TV distribution on home networks for local news and sportsball?

IPTV from your ISP is typically multicast (even if your connection is point-to-point), and if you have more than one network behind your router (for example, you have separate networks for wire clients, owner's wifi and guests wifi) you need to understand hot it works to setup your router correctly that you can watch IPTV on any device in any of yours networks.
