No, I don't want to make that distinction. The bottom line is money. Voom could only get 30-50000 subscribers to line up to get the service in the entire time they have been operating (and how many are freebies, like the dozens they handed out at the 2004 Oscars in the Gift Basket that don't generate revenue). E* now adds five times that in a single quarter. I would even venture a guess that a third of V* subscribers subscribe to either Cable, D*, or E* as well, as there are just way too many gaps in the programming lineup.
The bottom line is that HD is not ready for prime time as far as the bulk of the populace is concerned. We are early adopters who are ahead of the curve and don't mind paying $3K for TVs and $1K for receivers. When Analog TVs go away AND HD sets cost less than $300 at Best Buy, THEN you will see HD become popular. The vast majority of people with HD sets only use them to watch DVDs which aren't even HD. (I was one of them until 1/2004.... I had my HD set for two years until I saw my first HD broadcast on it)
As for E* only caring about Internationals, I will agree that they are more concerned with chasing the immigrant market than targeting affluent early adopters like D* and V* did. Plus when they are making $10-20 a CHANNEL with those it is easy to see why they are doing it.... They win the bang for the buck award for bandwidth utilization on a per subscriber basis, although I question just how many Japanese speaking subscribers they have that want the Japanese channels. If you are making $20 a subscriber, but only have 20000 subscribers to the channel is is worth the expense?
