It is certainly not a matter of technical superiority, for those who feel the Internet is the progenitor of the NII are not for the most part concerned with technology. That is, telephone service is defined by the telephone company. And though I may not enjoy and therefore not watch any network television show, I still must pay the advertising surcharge on products and services I buy, and I am denied the option of using my discretionary time as a couch potato, watching what I wish. Of course, the VCR has largely broken the network's tyranny over the time at which I view, the content is still theirs. Announce it on the appropriate mailing list and have at it.
Entry cost is low enough that extensive market surveys are a waste of time.
The Internet is a telecommunications tabula rasa, writable by all. The unique characteristic of the Internet which IMHO must be carried over into the NII because that's what people seem to appreciate most, is its two-way nature. Disarm vertical integration with the Universal Bearer Service.
