With the spread of the Internet as a medium and means of communication, especially after 2000-2001, the idea of the internet and information economy is created by the growing importance of e-commerce and electronic enterprises, including the concept of a global information society to understand a new type of “all connected” society. In the late 2000s, the new type of economies and economic expansion of countries such as China, Brazil and India brought attention and interest to others than the generally dominant Western economies and economic models. When a person undertakes to provide services to the person under an employment contract, he or she is classified as a service or a worker. The service is provided for a salary or salary and/or other benefits related to this work. The service may be in a government or private organization. European capture has become branches of the European states, the so-called colonies. The emerging nation-states, Spain, Portugal, France, Great Britain and the Netherlands, have tried to control trade through customs duties and (de Mercator, lat.: trader) was a first approach to intermeding between private wealth and the public interest. Secularization in Europe has allowed states to use the immense property of the Church for the development of cities. The influence of the nobles diminished. The first secretaries of state for the economy began their work. Bankers such as Amschel Mayer Rothschild (1773-1855) began financing national projects such as wars and infrastructure.
The economy now represented the economy as a theme of the economic activity of the citizens of a state. The old economy was mainly based on subsistence agriculture. The shekel was a reference to an old unit of weight and currency. The first use of the term came from Mesopotamia around 3000 BC. J.-C. and referred to a certain mass of barley that associated other values in a metric such as silver, bronze, copper, etc. Barley/scle was originally both a monetary unit and a unit of weight, just as sterling was originally a unit that denounced a mass of money with a pound. For example, when a person sells their old car via OLX, it is not considered a commercial activity. But if he regularly trades with Demauto in his theatre, it is considered a commercial activity. An economic activity is an input-based process that leads to the production of a service or the provision of a service. The classification of industries is divided into categories that allow, by aggregation, to define the economic sectors (agriculture, industry, construction, trade, etc.).
The first economist in the true modern meaning of the word was the Scotsman Adam Smith (1723-1790), who was inspired in part by ideas of physiocracy, a reaction to mercantilism and, later, economics student Adam Mari.  It defined the elements of an economy: products are offered at a natural price generated by the use of competition – supply and demand – and the division of labour. He said that the basic motive for free trade was the self-interest of man. The so-called assumption of personal interests has become the anthropological basis of the economy. Thomas Malthus (1766-1834) transposed the idea of supply and demand to the problem of overcrowding.
