I have an idea and VOOM can pay me for it if they would like. Here it is:
Survey existing customers to determine which OTA stations they are picking up. (maybe you can even do this remotely through the receiver) Then database market to customers in those same areas (by ZIP code, HDTV ownership, income, and even by topographic data) with a postcard that lists not only the VOOM HD channels but also the OTA channels that the customer will receive. In my area (the northern NJ shore) VOOM could pretty much guarantee reception of ABC, NBC, CBS, FOX, WB, UPN, and PBS in HD as well as another PBS, PAX, the network subchannels, and few others in digital.
I am sure there are many other areas of the country where VOOM can do the same thing.
This plan should only be used after VOOM has a DVR because the marketplace has shown that people would rather have less HD channels with a DVR than more HD channels without one.
