What is marketing?

The activities of a company associated with buying and selling a product or service. It includes advertising, selling and delivering products to people. People who work in marketing departments of companies try to get the attention of target audiences by using slogans, packaging design, celebrity endorsements and general media exposure. The four 'Ps' of marketing are product, place, price and promotion.
Many people believe that marketing is just about advertising or sales. However, marketing is everything a company does to acquire customers and maintain a relationship with them. Even the small tasks like writing thank-you letters, playing golf with a prospective client, 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

Marketing is one of the terms in academia that does not have one commonly agreed upon definition. Even after a better part of a century the debate continues. In a nutshell it consists of the social and managerial processes by which products, services and value are exchanged in order to fulfil individual's or group's needs and wants. These processes include, but are not limited to advertising.
A market-focused, or customer-focused, organization first determines what its potential customers desire, and then builds the product or service. Marketing theory and practice is justified on the belief that customers use a product/service because they have a need, or because a product/service has a perceived benefit.
Two major factors of marketing are the recruitment of new customers (acquisition) and the retention and expansion of relationships with existing customers (base management).
Once a marketer has converted the prospective buyer, base management marketing takes over. The process for base management shifts the marketer to building a relationship, nurturing the links, enhancing the benefits that sold the buyer in the first place, and improving the product/service continuously to protect the business from competitive encroachments.
Marketing methods are informed by many of the social sciences, particularly psychology, sociology, and economics. Anthropology is also a small, but growing, influence. Market research underpins these activities. Through advertising, it is also related to many of the creative arts.
For a marketing plan to be successful, the mix of the four "Ps" must reflect the wants and desires of the consumers in the target market. Trying to convince a market segment to buy something they don't want is extremely expensive and seldom successful. Marketers depend on marketing research, both formal and informal, to determine what consumers want and what they are willing to pay for it. Marketers hope that this process will give them a sustainable competitive advantage. Marketing management is the practical application of this process. The offer is also an important addition to the 4P's theory.
The four Ps are:

Product: The Product management and Product marketing aspects of marketing deal with the specifications of the actual good or service, and how it relates to the end-user's needs and wants.
Pricing: This refers to the process of setting a price for a product, including discounts. The price need not be monetary - it can simply be what is exchanged for the product or service, e.g. time, or attention.
Promotion: This includes advertising, sales promotion, publicity, and personal selling, and refers to the various methods of promoting the product, brand, or company.
Placement or distribution refers to how the product gets to the customer; for example, point of sale placement or retailing. This fourth P has also sometimes been called Place, referring to the channel by which a product or service is sold (e.g. online vs. retail), which geographic region or industry, to which segment (young adults, families, business people), etc.

Marketing is the delivery of customer satisfaction at a profit, where this process obtain through exchanging products and value with others.
