I wonder about this. The amount of bandwidth Apple would have to serve for iTunes TV streaming would be astronomical. Maybe in 5 to 10 years? I've heard the 30% they get for a 99c song download is marginally enough to cover costs. And that's roughly 5mb a song. How much would they have to charge to stream an hour of HDTV? But then I think, obviously profitable for Netflix to make it work. So maybe the bandwidth costs are greatly exaggerated.
Apple sold about $4 billion in Music, Movies, TV Shows and iOS apps combined in 2009, up 21% from 2008, and that figure has undoubtedly risen in 2010 and 2011 YTD. However, the iTunes store is essentially a "break-even business" for Apple. They might net $100 to $400 million in profit or less on $4 billion in sales. However, in the quarter ending end of March 2011, they had $24.67 billion in revenue and $5.99 billion in profit. Now I don't know what part of their quarterly revenue or profit was iTS/App Store, but when you sell 3.76 million Macs and 18.65 million iPhones, that's your bread, butter, and opera tickets. 30% on iTunes, Apps, etc. just keeps that part of the business afloat so they can sell us all that other fun stuff.
