Marketing Management is the leading marketing text because its content and organization consistently reflect changes in marketing theory and practice. The very first edition of Marketing Management, published in 1967, introduced the concept that companies must be customer-and-market driven. But there was little mention of what have now become fundamental topics such as segmentation, targeting, and positioning. Concepts such as brand equity, customer value analysis, database marketing, e-commerce, value networks, hybrid channels, supply chain management, and integrated marketing communications were not even part of the marketing vocabulary then. Firms now sell goods and services through a variety of direct and indirect channels. Mass advertising is not nearly as effective as it was. Companies are exploring new forms of communication, such as experiential, entertainment, and viral marketing. Customers are increasingly telling companies what types of product or services they want and when, where, and how they want to buy them.
