interesting…. but why not just purchase netflix…..
My 2 pennies guess (because I don't know much about it to be honest), I think Apple is looking for content. Even if Netflix is now producing unique and good content (House of Cards, Orange is the new Black, Arrested Development), they still don't "own" all other content they're streaming...
Being able to have iTunes as a direct "Music Label", as a "Movie Studio", or as a "Broadcast Channel"... it would maybe turn it as a new kind of "TV".
I don't know the deal TV Shows producers get with broadcast channel, but "what if" (it's a huge what if) Apple would allow an easier and more profitable solution to produce and distribute content we can only find on iTunes TV? (pretty much just like Netflix does now).
Most of the time, it cost between $2 and $3M to produce a TV Show episode (from what I read). So if Apple owns the content, they can easily distribute all over the world (and not have limitation like we know right now with different rights for distribution for each countries). By doing so, it could be way easier to have enough "customer" that will buy an episode. (it could just be 2 or 3 millions people worldwide with a $0.99 per episode... or more depending the distribution deal they could do).
With hundreds of millions of iOS and iTunes users (one clic away to purchase it), they could have a better business model to propose to content creators. Apple is probably trying to create a new business model for TV, starting from the beginning: the content creator for new content and not necessary the TV Channels that owns the current content.
Most of the time, some TV Shows get cancelled because of the schedule time (because each TV Channels want to have more ratings than the other they always put good TV Shows at the same time). But on a Netflix/iTunes base system, nobody cares about time... you just watch it when you want. Therefor, it will just be a matter of number of purchase download (or views if it's streamed with some kind of iAds).
So, it could make sense to have some guy (or team) that actually knows how to manage content creators. And maybe this is just the top of the iceberg...
But again, I don't know anything about TV... beside watching TV Shows, Documentaries and Movies
