Does anyone remember IP multicast?

I remember a lot of trade magazines in the late 1990's during the dot com boom talked about how important it would be.

https://en.wikipedia.org/wiki/IP_multicast

I never hear about it anymore. Is that because everyone wants to watch something different at their own time? Or is it actually working just fine now in the background? I see under the "Deployment" section it mentions IPTV in hotel rooms.

dumbing it down a bit: Imagine if anyone in your neighborhood could broadcast video and take up %N of the bandwidth to all of the routers in the neighborhood. Imagine this on your campus or at your office. This works for cable tv, as there's only 200 channels. You're just going to slurp up all of the bandwidth instead and maybe no one is watching the tv.

Sure you get these black swan events that everyone wants to watch, but they're just that, really infrequent. So instead you have to provision capacity if on the interent to do big events like this. The upside is that you have a billion people able to point to point to another billion people instead of 30 companies who can send to everyone.

Multicast isn't broadcast; bandwidth is only used on links with clients who have joined the group.
