Hmm PS Vue shutting down. This following news of ATT/DirecTV now losing a bunch of subs and raising costs. This doesn't seem to make a strong case for the long term prospects of these over the top cable replacement services.
The problem I see is that they are selling the same content as cable, thus with the same programming costs, and trying to do it at a fraction of the cost. Sure they don't have the infrastructure, but they also lack scale. I don't think they can exist long term as they are today. Eventually these companies will have to jack up prices to make them profitable and thus lose most of their draw, or they will shut it down like with Sony here.
