IMO Netflix has done well in this regard by transforming themselves into a content company rather than a content delivery service. Recently most of my favorite shows on Netflix have been 1st party titles, and I can't think of another content producer who's output is as varied and as high-quality as Netflix at the moment. Maybe Disney has the IP and the raw muscle to pull this off, but they will have to prove it.

I actually think competition is good for the space. As I said, I think Netflix is really good now, but if they became an uncontested monopoly in the streaming space, I would fear that quality would suffer.
