The topic of this document is the definition and the type of market. The place where supply and demand is meeting is the market. Basic functions of the market are: selective, allocative, distributive and informative. The market is defined as the exchange position as an economic process in which supply and demand creates price. In marketing theory and practice, the market can, as a complex concept, be divided into several types. In the market we meet with a large number of different customers who have different needs and whose motives are homogeneous, but they are very different and it is therefore necessary to carry out segmentation of the market. Market segmentation can be understood as an auxiliary tool in marketing research, but also as one of the ways of implementing a marketing strategy. Market structure makes the perfect and imperfect competition in which we stand, monopolistic competition, monopoly, duopoly and oligopoly. For the marketing business, it is necessary to distinguish between pure products, clean services, products that would be useless to use, services that would be unnecessary without the product.
