The term information revolution (sometimes called also the "informational revolution") describes current economic, social and technological trends beyond the Industrial Revolution. Many competing terms have been proposed that focus on different aspects of this societal development. The British polymath crystallographer J. D. Bernal introduced the term "scientific and technical revolution" in his 1939 book The Social Function of Science to describe the new role that science and technology are coming to play within society. He asserted that science is becoming a "productive force", using the Marxist Theory of Productive Forces. After some controversy, the term was taken up by authors and institutions of the then-Soviet Bloc. Their aim was to show that socialism was a safe home for the scientific and technical ("technological" for some authors) revolution, referred to by the acronym STR. The book Civilization at the Crossroads, edited by the Czech philosopher Radovan Richta (1969), became a standard reference for this topic.
Daniel Bell (1980) challenged this theory and advocated post-industrial society, which would lead to a service economy rather than socialism. Many other authors presented their views, including Zbigniew Brzezinski (1976) with his "Technetronic Society." .

Humanity has progressed from agricultural revolution to the industrial revolution and is now moving to an information revolution.
