I have a business model to launch a private television network into 10 test sites with a maximum of 102,000 sites. Strong revenue stream, unlimited content ideas. My question is, with so much technology facing this idea, what is the best medium to use. IPTV, satellite, or digital signage. Why IPTV? I do not know this industry, I know mine.  I am asking for technology advice. Any comments would be appreciated. This is a great site for learning and gaining information!
