LIVE BOARD Starts Japan's First Demonstration Experiment to Sell Outdoor Advertising Space as NFTs


LIVE BOARD, INC. (Headquarters: Shibuya-ku, Tokyo; President and CEO: Jun Sakurai; hereinafter, "LIVE BOARD"), in collaboration with Bridges, Inc. (Headquarters: Koto-ku, Tokyo; President: Yushi Masui; hereinafter, "Bridges"), CoinPost Inc. (Headquarters: Chiyoda-ku, Tokyo; CEO: Takahito Kagami; hereinafter, "CoinPost"), and Dentsu Inc. (Headquarters: Minato-ku, Tokyo; President and CEO: Norihiro Kuretani; hereinafter, "Dentsu") will begin a demonstration experiment using NFTs (non-fungible tokens) for the sale of outdoor advertising space.

NFTs, which became a hot topic in various places last year, are a technology that is able to guarantee the uniqueness of an object in the digital world. The current primary use of this technology is the distribution of digital content in limited quantities (i.e., having a limited supply). In addition, it is also beginning to be used as a basis for managing rights in the real world. By using NFT in actual transactions of rights, it is possible to open up the trading market to individuals on a more global scale, which contributes to the realization of a truly open market.

With regard to outdoor advertising, new ways of displaying advertisements are attracting attention, especially overseas. For example, in the U.S., the act of posting one's own NFT art on outdoor ads has become a meme*, and is accelerating. In this manner, the ways in which outdoor advertising space is purchased are becoming more diverse, and a seamless market is now being demanded, to accommodate these changes.

*The viral spread of an idea, behavior, style, or practice as a culture, through spreading as an object of imitation.

In light of this trend, LIVE BOARD will launch a joint experiment with Bridges, CoinPost, and Dentsu to test the conversion and sale of outdoor advertising space as NFTs. This also represents the first initiative in Japan to sell outdoor advertising rights as an NFT, and we will continue to explore the possibilities in the Japanese market.

A digital OOH ad network operator achieving data driven targeting and effectiveness verification

LIVE BOARD is the first company in Japan to achieve impression-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 the patterns of movement of people are prone to change. In addition, by combining big data from Japan's largest carriers with our proprietary network that comprises a wide range of digital OOH throughout Japan, including outdoor, indoor, train, and station OOH ads, we have enabled the delivery of personalized ads such as targeting by gender and age, which was not feasible with conventional OOH.
