This document discusses how outdoor advertising connects with large numbers of people as urban populations grow. It provides statistics showing more people now live in cities than rural areas, and cities continue expanding rapidly. The document then summarizes research showing people are still exposed to outdoor advertising as they commute and spend time outside, and that well-designed outdoor ads can entertain and engage people rather than interrupt them like other media. It concludes by noting that major global brands invest heavily in outdoor advertising as it helps build brand awareness and familiarity in a high-frequency manner.
