The accelerated development of information and communication technologies (ICT), from the end of the 20th century until today, has made a great contribution to all segments of social life, and a significant part of this contribution is the impact on modern economic trends. New forms of business, such as digital marketing, electronic banking, and the web market, have confirmed old and set new theoretical postulates in economic science as well, although there are still disagreements at the global level regarding the intertwining of the understanding of traditional economic flows and terms with newly introduced economic flows and terms.
