Abstract
A panelist response scanning system includes a plurality of product scanning units for location at respective stores, a targetable television system, a plurality of panelist identification means for identifying respective panelists, and a central processor for coupling to said product scanning units. The targetable television system head end transmits normal and substitute television program signals and signal substitution control signals to a plurality of panelist receiving stations. The control signals include panelist address signals corresponding to respective panelist identification means. Each panelist receiving station selectively substitutes substitute program signals in lieu of normal television program signals upon receipt of a respective panelist address signal. The product scanning units receive panelist identification from a purchaser of products from the respective store and receive product identification corresponding to such products and produce signals indicating the panelist and the product. The central processor responds to the product identification and panelist identification signals to provide an indication of panelist behavior in response to the normal and substitute programs.
