AbstractDesign as Mediating Interface: Historical Evidence and Symbolic Enunciation of the Radio Set. – Based on a case study on the invention of the radio station scale in the late 1920's and early 1930's, this article pleads for an interdisciplinary look at the importance of design as a mediating interface in the production‐consumption junction. In this cultural history perspective on technology, the material artifact matters both as a witness of and a sign for the symbolic meaning and appropriation of the technical object, which transgresses the functional logic of instrumental rationality. In presenting five different perspectives on design offering some alternative looks for a cultural history of technology, this theoretically inspired essay wants to sound the critical potential of a multilayered semantic approach to the radio apparatus as a prominent representation of a radical innovation in media technology.
