I asked a Best Buy rep and he said for most TV's the manufacturer sends a thumb drive with the content that they want shown on the TV's. That is why you usually see a continual loop. When a rep wants to demo the TV to someone they can open up different apps to show how it works.
The absence of substance of these "HIGHER INTEREST" posts is one thing that affirms my belief in this stock. Nobody cares that much about MY money unless they are trying to take it away from me!
