From glows to graphics: The invention of visuality in early electronic media systems

Abstract

By going through a history of electronic visuality, from fluorescence glows in European laboratories in the nineteenth century to the computer screen in the twentieth century, this paper discusses technical image operations in the interaction between media machines and media people. Examining this set of apparatus from the evolution of a neglected technical object – the vacuum tube, it traces the history of the screen and the temporal-spatial composition of electronic graphics in television, radar, and early computer systems. In doing so, it outlines the entangled history of analog and digital displays and demonstrates the impossibility of neglecting the role of the human observer in the technical invention of visuality.
