Well, all I can figure is that they either hate TV or Netflix lets them make shows for peanuts. This is disney, they have a bunch of channels that could just be ordered to carry the shows, so its not a problem with finding a network that wants it. so, I can only assume the shows shows will be made on a fan film type budget, because if cheapness isn't the case then there really isn't a reason to go with a company like netflix for stuff like original programming. Either way, it still feels like a way to screw over tv/physical media people.
As for netflix being the next big thing, when it comes to original media I doubt it. They're obviously very popular for what they do with video/movie streaming, but they won't be cornering the original show market anytime soon.
