I am not going to say that you are wrong, because there is no right or wrong here. But I am not sure that becoming a satellite TV "commodity" like the other services, and competing on price, is the right path for Voom.
Voom's promise, in my view, is to be to DirecTV and Dish exactly what Lexus and Infinity are to Ford and Chevy -- the high-end premium alternative.
If you started a new brand of corn flakes, and if you offered everything the others offered, sure you would be just one of the pack and would price yourself at or below the competition. But Lexus doesn't compete with Ford on price. They compete on quality, and yet both products are viable in the marketplace.
I think Voom's original idea was to be a premium service with exclusive HD channels for the upper crust -- just as Lexus is for the upper crust. Voom's exclusive content ideas originally spoke to that. Lexus cars are expensive, so Lexus does not have to sell as many cars as Ford in order to provide an excellent ROI to investors. Similarly, Voom would not have to have as many customers as DirecTV or Dish.
Somewhere along the line, Voom decided that 28,000 subscribers didn't cut it, and they changed course to include every commercial-ridden "me too" SD channel under the sun and compete on price. So be it, if it works. They will lose me, and they will lose people like me, who are seeking something altogether different: higher quality, commercial-free, best technology and best customer service, and are willing and able to pay for it.
The marketing strategy I recommend would be for Voom to offer every HD channel (pay through the nose for HDNet and INHD as necessary), add to their HD exclusives, come out with the utmost leading edge technology and PQ, a superb DVR, and the greatest customer "concierge" service, then charge a very premium price -- $150 plus.
I know so many people who have long since given up on TV for being garbage (just as I did). It would take time, but if Voom reached the right segment they could prove they are really different and much higher quality, and actually have something to offer to those who gave up on TV.
For those who are happy with the offerings of DirecTV and Dish, except they want them to be HD, I would say stick with those services and wait until they are eventually in HD, and you will get exactly what you want for a budget-conscious price. Don't ask Lexus to be like Ford.
