Just because Apple hasn't released a TV solution beyond the AppleTV doesn't mean they are not working on it. Just because Jobs killed a TV project also doesn't mean anything. Jobs killed absolutely every project except for Pro laptops & desktops and Consumer laptops & desktops when he took over as CEO. Apple was about to collapse, they were about 4-6 weeks away from financial ruin. Drastic measures had to be taken.
Apple is the only company that can disrupt the TV/Movie industry and deliver such an experience to the regular consumer. No one else can pull it off. The problem is cutting deals with the networks and content owners. HBO is one of the first. HBO has finally realized that Game of Thrones is the most pirated show on the Internet. That is because there are a hundred million plus people who wish to see it but cannot for various reasons. Most of them would pay if there was a way to do it without needing a cable or satellite contract. They have finally opened their eyes and seen the light. They can make more money selling direct worldwide then they ever could by bundling with cable and satellite. Once their sales numbers release, it will begin to make sense to other networks. They might be restricting the streaming to AppleTV and perhaps just the USA for the moment, but they should be ramping up their ability to stream to people worldwide. Because thats were the money is and that's where your customers are. Someone in South Korea, Germany, etc. should be able to connect to HBO Go and subscribe.
The level of piracy is constantly increasing and what's worse for the dinosaur media is that it is getting easier and easier and more and more user friendly. So much so that the executives for these companies should not be sleeping at night. The new consumers want the content but they want the freedom to view it on their own terms. They don't want DRM, they don't want restrictions nor barriers, they don't want annoying ads and they are willing to pay but not too much.
