Getting the content producers onboard is going to be a challenge since most are already in longterm contracts with the current cable and satellite providers.
I understand that Apple is attempting to do something similar (I've even heard of Siri voice capability as a cool possible feature), since Tim Cook wants to extend Apple's consumer reach to the living room (beyond their current limited-feature set top box offering) - Cook recently said, ?When I go into my living room and turn on the TV, I feel like I have gone backwards in time by 20 to 30 years.?
If anyone can pull off the next (r)evolution in television, I would bet on Apple (although it could be their undoing too)...
