This document discusses the changing role of marketing from a function to a way of doing business integral to the organization. It emphasizes the importance of focusing on customers and owning the market rather than just selling products. Smart marketing involves changing perspectives to prioritize customer ownership, consistency, and reinforcing the self through innovations, market creation, dominance and profits. Technology enables customization and two-way feedback between customers and companies, shifting marketing from a monologue to dialogue. Marketing now involves hybrid products and services rather than distinct categories.
