Now, if you're not the MPAA and so tied up and confused by unauthorized access, you might look at that information and realize that putting it on AMC's website was probably the mistake. That's not where people look for stuff these days. Yes, they made it free, but they didn't make it convenient, meaning they didn't put it in a form that some portion of consumers want, and watching it directly on AMC's website appears to take a large group out of their natural flow.
The problem with having to go to the station's websites for me is that I can't use whatever device I want. My Android devices (tablet, phone, and Google TV), all show that I cannot access it with that device, but need my computer. I subscribe to 3 popular paid streaming services... PICK ONE!
I also have a Pogoplug that I have been using for a few years, and bought a second one (on amazon for $20) that I wiped and installed a LAMP server on, it acts as a private web server. The down side of pogoplug is that you still access the files through their portal, so if they shut down, you lose the access ability, but the files and storage are yours.
Market driven changes won't work in this situation
The reason market driven changes won't work here is that there is an "industry standard" that everyone follows. If there was someone who offered an alternative, and that company had the ability to make the product available, then as people started leaving current providers to go to this new innovative service, then change may occur.
As it is, the industry players are entrenched and made it hard for any new players to enter the space.
