The traditional way of selling Out of Home media. A level of delivery that directly relates to the population of the market. Typical showing levels are: #100, #75, #50 and #25 Showings. The number of panels involved in an actual showing varies by market population and the average circulation level of the market’s inventory. With the industry migration to Geopath Ratings, this traditional definition must be translated into weekly levels of actual audience delivery in a standard media market.
