I haven't taken a journalism course. It's not even taught in most journalism schools. It makes it easier for you to understand a story. For example, in the style of 60 Minutes , there's rarely any history in a story. You will rarely see old footage or a section that explains the story you are about to see.
Different operations have different forms.
But this becomes a way of identifying both the information and the programming, and tuning in again. Well, they'll teach you. They may teach you how to be an on-camera person in your documentary film or television program, and they may teach you some aspects of it. And it's never revealed by the makers of it. And their eyes glaze over and they roll their eyes.
