Sometime around 1980, when I was still active in historical re-enactment I witnessed a local TV station filming the event. Part of their report involved an interview with one of the leading lights of the re-enactment movement.
It went like this:

With the camera focussed on the interviewee
Question ?
Response
Question ?
Response
and so on...

then with the camera focussed on the reporter
differently phrased question ?
differently phrased question ?
etc.

I assume the idea was to splice the footage up in the studio but it struck me, being suspicious of the media generally, that this technique was open to serious abuse. I haven't believed in a "talking heads" type report since.
