You set me off on a search of who owns the delivery systems.

Today, several large corporations provide the routers and cable that make up the Internet backbone. These companies are upstream Internet Service Providers (ISPs). That means that anyone who wants to access the Internet must ultimately work with these companies, which include:
UUNET
Level 3
Verizon
AT&T
Qwest
Sprint
IBM
You forgot Comcast (owner of NBC) and Time Warner that own quite a bit of content and can kill netFlix by imposing caps. On one had, I can’t really blame them. Imagine them having to spend, say, $10 Billion to upgrade the wires so NetFlix can save on postal stamps and improve their service.
