BUSINESS MODEL? OH MY GOD, what is the "business model" of HDTV? It's to attract as many warm bodies as possible around the radio, so you can freakin' sell to them when you run commercials. The same "business model" that has kept radio resiliant, and profitable for more than seven decades. That's the only "business model" allowed to commercial radio and tv stations, by the way, Freakin' DUH!
"What's your stupid question 700?" "Well it's 'what's the business model of stations broadcasting in HD?' Gee...I think it's to make the radios edible...so everyone will buy a new radio every time they get hungry! GET REAL!
