See, it's the buts that makes them want to differentiate the two. I think they are wise in how they are marketing them.To tell you the truth it would probably make the program providers less pissed off if they called them the same thing and said, you can get HBO GO for $15 per month, but it is streaming only, one device at a time (I have no idea how it will be). To get HBO GO, HBO, and HBO On Demand, order from your cable or satellite provider for $18, 19, etc...
