COMB Audience Measurement

Independent. In-Depth. Indispensable.

Leading advertising agencies ask, "Is it COMB approved?" to ensure the highest standard of accountability when planning out-of-home (OOH) advertising campaigns. That's because COMB has a 49-year history of conducting independent, in-depth measurement of OOH audiences under the scrutiny of advertising agencies, advertisers and leading out-of-home media companies. It publishes circulation and planning data for close to 80,000 OOH advertising faces in over 280 markets, providing a trusted, indispensable resource for media planners, buyers and sellers of out-of-home media.  COMB Member Companies

COMB data helps to validate the planner's thinking, intuition and experience.
