The presentation discusses how the role of the CMO is evolving (CMO 2.0) in response to changes in marketing brought about by social media and new technologies. Key changes include marketing shifting from being company-focused to individual and community-focused, and the importance of authentic engagement over traditional tactics like interruptive advertising. The new CMO must represent customers, take a strategic role, control the brand differently through communities and social networks, and employ new concepts like co-creation, word-of-mouth, and return on attention.
