Daily Effective Circulation DEC

The total number of persons, in cars or other vehicles, passing and potentially exposed to an advertising display for either 12 hours (un-illuminated – 6:00am to 6:00pm), 18 hours (illuminated – 6:00am to 12:00 midnight) or 24 hours. While circulation information remains a valuable component in the ratings system, they are not a measure of a targetable audience viewing advertising and are no longer endorsed as a buying and selling currency by the members of Geopath.
