As the pace of new OTT services has ramped up, I’ve been asked by a lot of industry colleagues and press which ones I believe have the most and least potential. It’s a great question, and while I don’t pretend to have a crystal ball, I certainly have my own opinions (as VideoNuze readers know!). But even as I’ve been sharing my thoughts, I’ve increasingly been asking myself – why is it, for example, that I’m more bullish about some (e.g. HBO Now), more skeptical about others (e.g. Sling TV) and more willing to be open-minded about still others (e.g. Apple’s and Verizon’s TV services)?
