The document discusses the transformation of marketing from Marketing 1.0 to Marketing 2.0. Marketing 1.5 is still optimized for traditional marketing with messages created inside the company and distributed outward. Marketing 2.0 involves being influenced by social media, integrating social contributions, and adopting more collaborative approaches. It recommends modifying investment strategies to leverage social media, measuring broader value beyond sales funnels, and developing meaningful strategies through continual evaluation of control, input/response, added value, and participation.
