  2. What is the difference between the DMA and CBSA?
    The DMA is generally larger than a CBSA in terms of square footage and population. The DMA is a television market area defined by Nielson Media Research that is also used by advertisers for multi-media planning. DMAs are non-overlapping and cover the entire United States. The CBSA, defined by the United States Office of Management and Budget, is a metropolitan area within a larger market (e.g. DMA) containing a substantial population nucleus, together with adjacent communities having a high degree of economic and social integration with that core. CBSA’s are a standard geography for buying and selling media.
  3. How do I compare the ratings to a showing level?
    A showing level represents a daily GRP. For example, a 25 showing is a daily 25 GRP. Our ratings are reflected in weekly impressions numbers and weekly target GRP numbers. Because a daily 25 GRP adds up to a weekly 175 GRP (7 days x 25 GRP) one is able to make the conversion.
  4. Why is transit inventory sold in packages?
    Transit inventory is sold in packages to represent different levels of exposure within the market. The packages act as a recommended buy and as well as a minimum. The impressions from a single King, for example, might not be enough to warrant costs of the creative and production of the vinyl banner. The seller would instead suggest a package of “X” Kings to capture a more substantial weekly GRP.
  5. How can transit be used to target demographic audiences?
    All transit media types can be used to target demographic audiences. For bus exterior and bus interior, audiences can be targeted by “Garage”. The “Garage” separates certain bus routes from other routes allowing one to target demographics. For in station advertising, specific “Stations” can be used to target audience while interior rail inventory can be targeted with “Lines” of rail or subway.
  6. What is the difference between an environment count and inventory count?
    The inventory count is the number of ads available in the transit system. For example, there are a total of 200 kings available for purchase. The environment count represents the number of buses or stations that the ads are on. For example, there are 100 buses used in the transit system. In conjunction, there are 100 buses which have a carrying capacity of 200 kings.
