So it's been great to see all the app-channels added to AppleTV this summer. And as I check out all the new ones each time they come out, I'm struck by one thing - I've never seen a commercial on one! WatchESPN just shows some of ESPN's own sports photos during breaks. For everything else, you might as well be watching Netflix. Except of course that I'm not paying anything. It's awesome. And it seems too good to be true. How could this be? Networks just going along with this disruption of the advertising model. I tried Googling to find articles addressing this. Something that might answer the burning question - How on earth did Apple pull this off?! Does anyone have a clue?
