A video program is broadcast to different video display sets in a broadcast reception area for display at the discretion of television viewers in that area. In order to determine the reaction of television viewers to the displayed broadcast video program, a determination of a relative number of sets responding to the particular broadcast is made. A display of the broadcast video program is provided with a pictorial representation of the relative number of responding sets. Potentially participating sets may be provided with a facility for registering any of a predetermined number of different types of viewer reactions to the broadcast video program. A display of the broadcast video program may be provided with a facility for displaying a number of pictorial representations corresponding to the predetermined number of different types of viewer reactions for individually indicating each viewer reaction type. Viewer reactions received through the registering facility may be displayed in the display of the broadcast video program according to reaction type through the corresponding pictorial representations.
