The concept of the long tail is a denial theory of an Italian scientist, Vilfredo Pareto.
Pareto proportions had been observed in the distribution of wealth in nineteenth century England. According to the economist, 20% of the effort is responsible for 80% of the results. The theory has been repeatedly used to describe the accuracy of different phenomena, not only in the field of economics. According to this rule, sellers should only choose to offer the 20% of products that enable the company to get 80% of its revenue.
hanks to the Internet and new technologies (drop shipping, electronic products) delivering less popular products and services to a narrow group of consumers has become economically efficient. Digital economy, in contrast to the traditional one, is not limited in terms of distribution channels. Due to these features, there is no reason for online sellers to give up the remaining 80% of their products.
