The DOOH Trust label was launched in 2018 at the industry's request to evaluate and certify the distribution of DOOH campaigns with the aim of bringing more transparency to this rapidly developing media. Today, more than 30,000 DOOH screens are subject to DOOH Trust certification from the ACPM, bringing together 12 sales offices and 5 media agencies. From now on, thanks to the developments of the ACPM, member agencies have access to the time slots of their DOOH campaigns certified by the ACPM and will also be able to share them with agencies.
