Abstract:

Much of the work of measuring the impact of television consists of measuring the extent to which the viewers enjoy what they choose to view. There are two main systems of measuring reaction to television programmes. The first is to "rate" the programme in some way or another. The other method of audience, reaction measurement involves the simultaneous recording of reactions by a comparatively small group of viewers who indicate their liking' or disliking of what they are viewing by pressing a button.
