Netflix has a large amount of great material. As I see it, the are not going away any time soon.
Oh no, I don't think Netflix is going away.
I think the key thing you said is here:
"There is no way that I will subscribe to every service just to have a similar bill."
THAT is exactly what I think is going to be required to get the same delivery of content that cable currently offers. Cable is a one stop shop. You get all the channels you want from them and you pay for all those services at once.
There are some who don't need certain things and definitely don't want 90% of the channels they get, but there are tons who want the live sports, the live shows, the very good live quality that now comes from these broadcasts, and other services don't measure up and won't be able to measure up from a single provider. Netflix, especially, is at the whim of so many content providers that their only real option is to create their own content and become an important player because of their original content, not because of their 'content on loan'.
But, then they are competing with a ton of other content creators who will find that they can also charge 10 bucks a month directly to consumers for the content they create. Disney is definitely doing this. CBS ALL Access is putting together a setup with Star Trek original content airing year round.
This just goes down the line until it takes half a dozen online providers along with an over the air antenna and a home made DVR setup to record some live shows and....
Geez, this is really a headache for the average consumer who had one cable bill and got everything they wanted from one place.
No...
Netflix isn't going away, but they are going to have 3rd party content issues in upcoming years that will make them a less attractive option. And that's all they will be in years to come. One option out of many.
