The waves of digitalization are highlighted, the dynamics and components of its material basis - the Information and Communication Technology (ICT) - are studied. Methods of mathematical statistics and common methods for analyzing time series, economic cycles and trends, structural shifts, regressions were used. Databases of such specialized agencies as UNCTAD, WTO, OECD, the US National Scientific Council, the Bureau of Economic Analysis USA, etc. are used as the main sources of digital and factual information.
