PRECISE MEASUREMENT OF POINT-OF-SALE PROMOTION IMPACT

摘要

A method for distribution of information includes displaying a sequence of promotional images at known, respective display times on a display terminal (30) facing customers (40, 42, 44) at a point of sale. Sales of different products at respective sale times are recorded on a sales terminal at the point of sale. A relationship between the sales times of at least one of the products and the display times of at least one of the promotional images is measured. Responsively to the relationship, a change is made in the sequence of the promotional images that are displayed on the display terminal.
