Billboard advertising is a traditional OOH advertising format, but there has been significant growth in digital OOH (digital billboards and place-based networks) in recent years; for example, about 4,900 digital billboard displays have been installed in China and the United States. The digital out of home trend is rising in Pakistan as well. Traditional roadside billboards remain the predominant form of OOH advertising in the US with 66 percent of total annual revenue. Today, billboard revenue is 73 percent local ads, 18 percent national ads, and 9 percent public service ads.

Transit advertising is typically advertising placed on anything which moves, such as buses, subway advertising, truck side, food trucks, and taxis.The book highlights OOH tools and techniques employed by marketers.
