Outdoor advertising creates reach, is highly visible, and the individual selection of locations allows us to accurately address target regions. It is part of the modern cityscape, is generally observed and expected by the population, and thus generates credibility. The exposure to relevant posters, citylights, digiscreens, or megaboards often takes place in waiting situations. This motivates people to turn to mobile as well as digital media, thus enabling a campaign extension into the digital space. Our OUT OF HOME TO MOBILE shows the development of interaction possibilities starting from advertising in public spaces to the use of websites and finally to online offers.
