Abstract
A method of limiting the number of presentations or observations of information items, such as advertising images, that are repetitively distributed among a plurality of transmitted materials is presented. In accordance with the principles of the invention, information items are compared, using identifiable properties, to similarly identified information items that have been previously received and stored in a dynamically created and updated data base of information items. When a count of number of the occurrences of a selected information item with same, or substantially similar, identifiable properties achieves a selectively set threshold value, the selected information item is precluded from being presented or observed in subsequent transmissions or broadcasts.
