Doorstepping is a word often used in media circles to describe a form of interview, usually with a politician. It derives from the old tradition of literally conducting interviews with people on their doorstep. You see it a lot with British politicians leaving their homes surrounded by reporters and cameras.
There is a famous scene in the movie Notting Hill where Hugh Grant’s character opens his front door to a wall of flashing cameras. That is what you call a doorstep. But doorstepping has become a colloquialism for managed street-side interviews too.
