It's all about content. What Apple could do to help things along would be to take about 10 billion and hire the best writers and producers around the world to create original content for Apple TV. If they have great original content, i.e.
"Breaking Bad, Mad Men, etc. that can only be accessed on ATV more people will want ATV and more will buy ATV. Prying content providers away from exclusive cable control is all about money. Content providers want money and cable companies give it to them. Until content providers can make more money without cable than they do with cable, things will continue as they are.
