LIVE BOARD, INC. and MCDecaux, Inc. are pleased to announce that through collaboration with VIOOH, the world's leading premium digital OOH supply-side platform (SSP), they have enabled global transactions utilizing impressions (VAC)*1 based on the estimated number of people who actually viewed an advertisement. This is achieved by leveraging NTT DOCOMO's location data and analytical technologies.

Additionally, through the expansion of our distribution network via the integration of the LIVE BOARD Marketplace*2 and VIOOH, we are also advancing preparations for launching trading within Japan. Trading utilizing VAC is expected to become available soon on "Cityscape®", which is operated and managed by MCDecaux.

*1 LIVE BOARD uses impressions that take into account the visibility rate based on visibility surveys (VAC = Visibility Adjusted Contact / total number of people who saw the ad), as recommended in the OOH Global Measurement Guidelines. Of the number of people in the viewing area of a medium (OTS = Opportunity to See), the number of people who may come into contact with an OOH ad (OTC = Opportunity to Contact / takes into account the direction of movement within the viewing area and the presence of obstacles) is defined. The number of people who are likely to actually see the advertisement (VAC) is estimated by adding the visibility rate for each media to this number.
*2 Refers to the entire advertising platform operated by LIVE BOARD, including functions such as SSP (Supply Side Platform) and DSP (Demand Side Platform).

■About LIVE BOARD, INC.
An operator of a digital OOH ad network that achieves data-driven targeting and effectiveness verification.
LIVE BOARD is the first company in Japan to achieve impression (VAC)-based advertisement delivery in OOH. We deploy advertisement delivery and billing systems in accordance with actual conditions that are based on the estimated number of viewers "at that time, in that place, and for that specific ad," even during the COVID-19 pandemic, when people's movement patterns are prone to change. In addition, by combining big data from Japan's largest carriers with our own network, which includes a wide range of digital OOH across Japan, including outdoor, indoor, train, and station OOH ads, we have been able to deliver personalized ads, such as targeting by gender and age, that was not possible with traditional OOH.
