The document summarizes a discussion between Tim Suther, CMO of Acxiom, and Emily Cavalier of Argyle Executive Forum on May 5, 2011 about the shifting balance of power between brands and consumers. Suther argues that for marketers to succeed, they need to 1) leverage proprietary customer insights to engage audiences, 2) develop multidimensional insights into customers, 3) create a marketing "central nervous system" to sense and respond to customer actions, and 4) coordinate personalized experiences for customers. Suther estimates that applying these capabilities could increase returns by 15-30% for most brands.
