A UK startup Bidooh is using advanced technology to create targeted billboard advertising. The platform uses AI profiling combined with blockchain technology to match the adverts to the attributes of the passersby. The digital display will therefore change its appearance to best suit the profile of the passerby. Sex and age are both characteristics that could affect what adverts members of the public see. The goal is to better target audiences so clients can design their ideal campaign, and also receive weekly market research reports regarding who saw them.
