The initial days of the industrial revolution saw dramatic changes taking place in the overall functioning of business organizations. The task of selling the goods was no longer a simple exercise as the meeting of the buyer, and seller at a marketplace and carrying out the exchange. The businesses grew big and the goods were manufactured at a large scale and were not sold out in small areas where the manufacturer could personally sell them. At this stage, the marketing department evolved, which served as a link between the buyer and the seller. In the process of marketing, the people who carried out the activity of making the product available to the customers had to function in a different set of circumstances that could not be managed in the way the other departments of the company were managed. So, the business organizations evolved a separate department that came to be known as the sales department and the process of managing this department as sales management. The definitions and concepts are further elaborated here in.
