The largest contribution to growth will be made by investments in advanced advertising on traditional outdoor displays (OOH). External digital displays (DOOH) will begin to overtake the classic or static OOH. Analysts predict the highest growth in markets with high infrastructure investments, such as China, Brazil and Turkey. In the so-called mature OOH markets such as e.g. England and Belgium, however, DOOH will begin to completely displace the classic OOH. The world capitals will shine in a whole new image. DOOH penetration will be highest in the urban environment with the highest population density and frequency. By 2019, DOOH supposedly accounted for 60% of the total OOH market in Singapore and almost 54% in England (Out-of-home advertising, 2016).
