A: Princeton, New Jersey, United States
In 1962 Austrian-American economist Fritz Machlup of Princeton published The Production and Distribution of Knowledge in the United States.
In this book Machlup introduced the concept of the knowledge industry or the knowledge-based economy.
"He distinguished five sectors of the knowledge sector: education, research and development, mass media, information technologies, information services. Based on this categorization he calculated that in 1959 29% per cent of the GNP in the USA had been produced in knowledge industries" (Wikipedia article on Information Society, accessed 04-25-2011).
