ABSTRACT
The first definition of the term ‘network’ appeared 200 years ago in Europe. At the beginning, the network was considered to be a circulation machine as well as an instrument for the creation of new specific territories. The network appeared later as a territory-destroyer, knocking over spatio-temporal references and scrambling geographical scales with the appearance of high-speed transport means (highways, trains, planes) and the diffusion of telecommunications. Nowadays a network appears as a set of specific modalities of transactions between people or organizations.1
