This document discusses key media concepts for setting media objectives, including impressions, reach, and frequency. It defines impressions as an individual's exposure to an ad. Reach is the number of unduplicated households or people exposed to a program or commercial at least once. Frequency is the average number of times a household or person views a program, station, or commercial during a period. Examples are given for setting reach and frequency goals based on factors like the product life cycle, target market breadth, and purchasing cycle.
