Academic question regarding public multicast.

Hi all,

I have had this question for a while now and I cannot seem to get it out of my head.

Why has multicast failed on the Internet? Why isn't a service like a TV channel where you can join their public IP address/FQDN and watch live streaming? I mean with all the public videos going on in youtube/facebook/instagram, you would have thought that this would be the norm by now, but its not.

Wouldn't multicast be cheaper and more efficient than unicast in that situation?

And if ISPs could configure multicast addressing, wouldn't it make it easier to watch IPTV everywhere? Why isn't this a thing yet?
