"Cybernetics was the first conventionally published book, rather than a technical report, to include a serious discussion of electronic digital computing." (Origins of Cyberspace 991 refering to the French edition which preceded the American by a few months). This book introduced the term cybernetics and clarified the questions raised by the rapid development of computing technology in the mid twentieth century. Cybernetics "has contributed to popularizing a way of thinking in communication theory terms, such as feedback, information, control, input, output, stability, homeostasis, prediction, and filtering." DSB (1981), v.14, p.347.
