In The Ape, the Adman, and the Astronaut: Rediscovering the power of storytelling, Ogilvy & Mather Worldwide Chief Creative Officer Tham Khai Meng posits that the way to move people is through telling a great story. In the advertising world, there’s forever been a struggle between the right brained and the left brained, the creative types and their reason-seeking counterparts. Despite longstanding evidence that humans are emotional and irrational creatures, creatives—the storytellers—have long been fighting for relevance. Khai says the battle has been won; the rise of social media has helped changed the landscape for good. People gravitate to great stories, and they share them with others. Thus, advertisers can’t look at storytelling as merely an option. It’s a must.
