The Emergence of the Information Society
About thirty years ago, social scientists started to study social and economic development in Western countries, emphasizing the transitory nature of these changes. Colin Clark ( 1941) analytically divided any economy into three main components: primary sector -- agriculture, secondary sector -- manufacturing and industry, and tertiary sector -- services. Any economy is a mix ture in different proportions of each. He argued that as a nation becomes industrialized, a large proportion of the labor force enters manufacturing. As national income rises, because of sectoral differences in productivity, the demand for services and information rises. Several European theoreticians, such as Radovan Richta ( 1967), Serge Mallet ( 1963), and André Gorz ( 1968) have emphasized the decisive role of science and technology in transforming industrial structure in society. Brzezinski ( 1970), Ellul ( 1967), Galbraith ( 1967), and Lewis ( 1973) have developed theories that affirm the fusion of science and technology with the advanced working class.
Daniel Bell ( 1973) and Alain Touraine ( 1971) realized that industrial society no longer exists in developed countries. To Bell, a postindustrial society is defined by the expansion of an economy of services and the centrality of theoretical knowledge with a dominant class of professionals, engineers, technicians, and scien-
