This should not come as a surprise. Folks are watching shows on Netflix, Hulu, and others through their phones and tablets. Maybe on their TV too. And the ability to watch these shows anywhere, at home, on the go, or even at work makes this new video watching behavior easier.
But while mobile is important, what's more important is that online services makes the whole season of a show available at the same time. With all two seasons of Scandal on Netflix, I would not have been able to binge watch it since Sunday night.
