Andrew Keller, CEO of agency CP+B, recently sent an email screed to all staff, intended as a call-to-action of sorts--for the agency and for the industry. In it, he outlined, at length, the state of the brand world and his forecast for where things were headed, talking about brands and agencies changing culture, about social media as a behavior rather than a medium, about content creation, and just generally creating a brand that was fit for the modern era. An edited version of the email appears here.
