Cord-cutting is a popular phrase these days. The act of getting rid of the overpriced cable or satellite subscription bill is certainly appealing, but is it practical for most people? Many of us no longer watch shows live — we’ve become a DVR generation. But there is a catch to that, as live sports are still the biggest draw on US TV. Recently Fox Sports streamed the Super Bowl, and it did so without restriction. In other words, you didn’t need to prove you were a customer of Dish, Comcast or any other money-pit. You just tuned in, dealt with the ads, and watched the game. That isn’t the norm, sadly, but the exception. Many channels on devices like Roku still come with that tired old requirement, but the recent NFL-Fox stream shows that these things may be headed for change.
