The document discusses key differences between traditional and digital marketing mental models. It notes that the digital landscape features pull communication rather than push, interactivity instead of broadcasting, real-time response, one-to-one communication, many-to-many engagement through social media, and an earned and owned media ecosystem without time-space boundaries. Marketers are encouraged to think of digital marketing as having these characteristics rather than following traditional broadcast, one-to-many, paid-only approaches.
