Network end users to pull down 2 gigabytes a day, continuously?

The problem with this all (or mostly) VoD model is the entrenched  
culture. In countries outside of the U.S. with smaller channel  
lineups, an all VoD model might be easier to migrate to over time. In  
the U.S., where we have 200+ channel lineups, consumers have become  
accustomed to the massive variety and instant gratification of a  
linear lineup. If you leave it to the customer to choose their  
programs, and then wait for them to arrive and be viewed, the instant  
gratification aspect is lost. This is important to consumers here.

While I do not think an all or mostly VoD model will work for  
consumers in U.S. in the near term (next 5 years), it may work in the  
long term (7-10 years). There are so many obstacles in the way from a  
business side of things, though.
