SEIBU RAILWAY :Ikebukuro Line, Shinjuku Line, Haijima Line, ToshimaLine, Sayama Line, Seibu Yurakucho Line.
In-train vision - 5,160 "Seibu Smile Vision" screens now integrated via
the LIVE BOARD network for digital out of home (DOOH) advertising.

LIVE BOARD,INC. is excited to announce that "Seibu Smile Vision" screens in trains on the Ikebukuro, Shinjuku,Haijima, Toshima, Sayama, and Seibu Yurakucho lines, which are sold via SEIBU RAILWAY Co.,Ltd. will be connectedto the LIVE BOARD Marketplace as of December 11, 2023. In addition to the conventional sales method that specifies
the delivery period and number of ad plays, NTT DOCOMO's location data and analysis technology will be used todevelop a model that provides an estimated number of passengers and viewers in each station, enabling a new andenriched method of selling digital media based on the estimated number of people who actually viewed theadvertisement. Impressions (VAC)* sales based on the number of people who can be estimated to have actuallyviewed the advertisement will also be possible.
* LIVE BOARD uses impressions that consider 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 thedirection of movement within the viewing area and the presence of obstacles) is defined. The number of people who are likely to actually see theadvertisement (VAC) is estimated by adding the visibility rate for each media to this number.

LIVE BOARD will continue to create new value for the expansion of the OOH market by implementing effective andefficient operation of transportation advertising, and further promote the realization of advertising distribution
tailored to diverse lifestyles.
