Each one of these inventions led to a serious revolution in the capability to track record and disseminates information. The first large-scale mechanized information system was Herman Hollerith's census tabulator. Invented to process the 1890 U. S. census, Hollerith's machine represented a major step in automation, as well as an motivation to build up computerized information systems. Among the first computers used for such information handling was the UNIVAC I, installed in the U. S.
