That's not it, they came up against the impenetrable barrier of a
business model. We understand how to price peering and transit of
traffic where all packets are the same, but nobody has any idea how
you do it where some packets are more valuable.

I never figured out why multicast failed.  It is bizarre that people are dumping
cable service which has 100 channels multicast to all of the customers in favor
of point-to-point service where you frequently have a zillion people streaming
separate copies of the same thing, e.g., a football game.  We fake it with CDNs
that position servers inside retail networks but really, it's multicast.
