Der Entwurf interaktiver Computersysteme war vom Ende des 2. Weltkrieges bis zur Gegenwart durch eine Reihe wissenschaftlichen Theorie und bestimmte Vorstellungen über den typischen Nutzer des Computers geprägt. Gemeinsam war den an dieser Entwicklung beteiligten Akteuren die Überzeugung, dass die Frage der Wissensrepräsentation und –vermittlung den Schlüssel eines guten Systementwurfs darstellt. Es wird der Frage nachgegangen, welche Wechselwirkung es zwischen diesen Vorstellungen vom Benutzer eines Informationssystems und den in den vergangenen Jahrzehnten entwickelten Systemen gegeben hat.

This article surveys the prehistory of broadcasting in the German Reich. It focuses on wireless telegraphy, where the Telefunken Company succeeded internationally with its quenched spark system on the eve of the war. Telefunken's system was developed as an efficient military technology between 1905 and 1908, and it soon became the core of Telefunken's successful attempt to break Marconi's monopoly in maritime radio communication. Encouraged by this success, Telefunken started to establish wireless transoceanic connections to build a global German radio network. The properties of radio broadcasting as a possible new mass medium only gradually became evident before 1918.

On May 27, 1903 the “Gesellschaft für drahtlose Teleg- raphie m.b.H.” (System Telefunken) was established as a subsidiary of the Allgemeine Electricitäts Gesellschaft (AEG) and Siemens & Halske AG. In the following years the new enterprise, which had a practical monopo- ly in Germany, was aggressively seeking markets both in Europe and in North America. In marine uses radio was filling a gap in the existing communications technology large enough to give Telefunken a chance to establish itself. In German merchant shipping, wireless stations were at first considered a dispensable luxury, that were useful only for large shipping companies for …
