This document discusses the importance of social media for shopping centres. It provides statistics showing that over 50% of the world's population is under 30, social media has surpassed pornography as the top online activity, and Facebook would be the third largest country by population if it were a nation. It also notes that awareness of Facebook is close to 100%, over 1 billion people use social networks, and traditional advertising campaigns have only an 18% positive ROI while people increasingly skip ads. The document advocates for shopping centres to engage with social media to understand what customers are saying about their malls online.
