The goals of reach, frequency, opportunity to see, gross rating points, effective rating points, cost, continuity, and gross impressions drive the media selection process. Reach identifies the number of people, households, or businesses in a target audience exposed to a media vehicle or message schedule at least once during a given time period. Frequency is the average number of times an individual, household, or business within a particular target market is exposed to a particular advertisement within a specified time period. Gross rating points (GRPs) measure the impact or intensity of a media plan. Cost per thousand (CPM) is one method of finding the cost of the campaign by assessing the dollar cost of reaching 1,000 members of the media vehicle’s audience. Cost per rating point (CPRP), a second cost measure, assesses the efficiency of a media vehicle relative to a firm’s target market. Ratings measure the percentage of a firm’s target market that is exposed to a show on television or an article in a print medium. Continuity sets the schedule or pattern of advertisement placements within an advertising campaign period. Gross impressions are the number of total exposures of the audience to an advertisement.
