As early as the 20th century, with the development of economy and the rise of circulation service industry, various types of information exchange centers, data centers and consulting institutions began to have a certain scale, and initially formed an information service system oriented to social and economic development. In this period, the information service, although the relationship between the various parts of the information service is loose, is in the stage from spontaneous dispersion to coordinated and orderly development in the service business. Since the mid-20th century, with the development of economy, science and technology and the combination of information resources development and utilization, the information service industry has gradually emerged, and the information economy has gradually become a new economic form, which has led to the formation of a new cultural model and development model.
