Marketing is not upto Selling a product??

Most of the people believe that marketing is just about advertising or sales. Moreover, marketing is everything a company does to acquire customers and maintain a relationship with them. From very small tasks like writing thank-you letters, returning calls promptly and meeting with a past client for coffee can be thought of as marketing. The ultimate goal of marketing is to match a company's products and services to the people who need and want them, thereby ensure profitability.
