Andrew Wallenstein: “I have seen the future of TV, and it is CNNgo. If the mere mention of a digital extension to a network triggers reflexive skepticism, that’s understandable; all they really do is just mimic linear channels or on-demand libraries. But CNNgo, currently available at no extra charge to participating pay TV providers, is a rare example of actual innovation. I sampled it during a 10-day free trial that that left me craving more when it ended last week.”
