Missed yesterday’s episode of Master Chef? Don’t worry, it’s already online. All you have to do is look up your latest TV bill, then go online and get a web account with your pay TV provider, leave that site, go to Fox.com and log in with your pay TV credentials. And then keep logging in again and again every month. Welcome to the new world of TV Everywhere, where TV watching is as complicated as online banking. Fox is the first broadcaster to introduce this kind of authentication, by mid-August, but similar requirements are already in place for anyone who wants to watch anything on HBO Go as well as new episodes of some cable shows on Xfinity.tv and DishOnline.com. Expect other broadcasters to follow suit soon, and be prepared to show your cable customer ID at the door of the majority of TV-content catch-up sites.
