In its most fundamental sense, a market is any public place where products or services are bought and sold, either directly or through intermediaries. It also refers to the aggregate of people with the present or potential ability and desire to purchase goods or services. Securities markets, such as the New York Stock Exchange, are an important facet of markets in the financial domain.
A medium of exchange is any commodity or product that is universally accepted in a market for the purpose of trade and that functions as a standard measure of value and wealth.
