> Imagine you could send an audio or video stream to potentially everyone with internet access in the whole world but would need to pay only for the bandwidth of exactly one stream. That would be very nice for you, or Spotify, or Netflix, but not such a good deal as the current one for your ISP. This mostly happens with Akamai [1] and Netflix [2] CDN appliances on edge networks though (content caching boxes used to offload transit or peering fabric traffic). I'd argue Multicast didn't take off because of "tragedy of the commons" issues; ISPs don't want to support additional complex network routing technologies (at additional, substantial cost) when existing one to many unicast solutions (mentioned above) are sufficient.
