Gross Rating Point (GRP)

Represents one percent of the target market reached. For example, a television program delivering five GRPs is reaching five percent of the target audience being measured. In a media schedule where multiple ad exposures are being delivered, the GRPs are determined by multiplying the reach of the schedule and the average frequency of exposure. A reach of 30 and frequency of 3X would calculate to 30 X 3 = 90 GRPs. Sometimes used interchangeably with Target Rating Point (TRP).
