Book excerpt: This textbook is written to be brief and straight to the point, because it is intended for entrepreneurs to use as a manual of marketing principles for battling business competitors as if they were fighting a marketing war. Entrepreneurs running private start-up companies in a marketing war might not get defeated until the small behave like the big or emulate the Giants. To the way the author thinks, marketing battles are not fought in physical places like the aisles of a physical store. Nor are they fought in the streets of a city like Pittsburgh, PA. Instead marketing battles are, according to this book's perspective, fought inside a customer's mind, which can be very tricky. Instructors and students alike should be able to find this book straightforward and concise with its explanation of the key marketing concepts and theories. This book can be used not only for teaching entrepreneurship/marketing majored undergraduate students the principle of marketing course, but for teaching related undergraduate courses like promotion management or retailing or sales management. Here, concepts and theories in marketing are referred to as principles, while the use of principles to address the specific subjects of retailing, marketing communications and sales leadership are referred to as applications in each of the book's ten chapters. A list of all concepts and theories discussed in the book is provided towards the end of the book. Exercises are available at the end of each chapter to facilitate experiential learning through marketing plan writing and role-play performance.
