Dear all, 60 years ago the German sociologist Theo Pirker made the assertion that machinization of information leads to rapid expansion of information volume and to broadening the stream of information. I used this approach in my paper on punch card technology in Germany in the recent issue of the German journal Technikgeschichte. I showed how the introduction of punched cards induced the first information explosion in history. Further I raised some doubts on the current view that the industry in the United States were leading in the application of punched cards based control systems. I showed that in Germany the industry reached the same level of punched cards based control systems as in the United States. On your demand I can provide an English translation of my paper as a working paper 1/2017.
