Nothing is difficult to understand. Most people seem to understand clearly that Apple is doing the exact same thing that Netflix, Hulu, Amazon, and other streaming services are doing. The difference is, Apple's marketing is telling the audience they aren't doing what others are doing. They're presenting it as something different. Marketing it as Quality instead of demographic programming. Buuuuuuuuuuuuut...
when you look at the programming on offer, both finished and future product, you can clearly see the intended demographic for each of the shows.
So no Apple isn't trying to duplicate a regular TV channel. None of the streaming services are trying to do that. Never have really. Apple is trying to do the same as the other steamers: find content that will connect with the consumer. Apple will have something geared towards the young kids, pre-teens/teen agers, young adult, adults, men, women...
The example you gave of Apple hiring a director to produce some shows isn't a unique thing. I doubt you can find a streaming service that hasn't done that. You really can't. Apple is simply trying to market their streaming service as something different, when it is simply a streaming service. Content will determine it's success. Just like with every other streaming services.
Apologies for length.
