Reading Between the Lines
volume 01 issue 02/2012 READING BETWEEN THE LINES A TRANSNATIONAL HISTORY OF THE FRANCO-BRITISH ‘ENTENTE CORDIALE’ IN POST-WAR TELEVISION1 Andreas Fickers Maastricht University Grote Gracht 90-92 Postbox 616 6200 MD Maastricht The Netherlands [email protected] Andy O’Dwyer BBC Research Centre House 56 Wood Lane W12 7SB London United Kingdom [email protected] Abstract: In 1950 and 1952, the British Broadcast Corporation (BBC) and Radio Télévision Française (RTF) realized the first transnational television transmissions ever. The so called ‘Calais Experiment’ (1950) and the ‘Paris Week’ (1952) were celebrated as historic landmarks in European television and celebrated as a new ‘entente cordiale’ between the two countries. This article aims at highlighting some of the tensions that surrounded the realization of these first experiments in transnational television by embedding the historic events into the broader context of television development in Europe and by emphasizing the hidden techno- political interests at stake. In line with current trends in transnational and European television historiography, the article analyses transnational media events as performances that highlight the complex interplay of the technical, institutional and symbolic dimension of television as a transnational infrastructure. Keywords: Transnational history, BBC, RTF, Eurovision, experimental television 1 Introduction What is generally praised as the first instance of transnational television and an historic landmark in European television history, the Franco-British ‘Calais experiment’ of August 1950 and the ‘Paris week’ of July 1952, is in fact a perfect showcase to demonstrate both the ambitions and the challenges of institutionalising the new medium of television as a “champion national” both in Britain and in France. -

The History of Television
The History of Television Television was not invented by a single inventor, instead many people working together and alone over the years, contributed to the evolution of television. At the dawn of television history there were two distinct paths of technology experimented with by researchers. Early inventors attempted to either build a mechanical television system based on the technology of Paul Nipkow's rotating disks; or they attempted to build an electronic television system using a cathode ray tube developed independently in 1907 by English inventor A.A. Campbell-Swinton and Russian scientist Boris Rosing. Electronic television systems worked better and eventual replaced mechanical systems. German, Paul Nipkow developed a rotating-disc technology to transmit pictures over wire in 1884 called the Nipkow disk. Paul Nipkow was the first person to discover television's scanning principle, in which the light intensities of small portions of an image are successively analyzed and transmitted. In the 1920's, John Logie Baird patented the idea of using arrays of transparent rods to transmit images for television. Baird's 30 line images were the first demonstrations of television by reflected light rather than back-lit silhouettes. John Logie Baird based his technology on Paul Nipkow's scanning disc idea and later developments in electronics. Charles Jenkins invented a mechanical television system called radiovision and claimed to have transmitted the earliest moving silhouette images on June 14, 1923. Electronic television is based on the development of the cathode ray tube, which is the picture tube found in modern TV sets. German scientist, Karl Braun invented the cathode ray tube oscilloscope (CRT) in 1897. -

The Achievement of Television: the Quality and Features of John
Investigations into the Emergence of British Television 1926-1936 1 Investigations into the Emergence of British Television 1926-1936 November 2017 A Critical Review submitted to Aberystwyth University in partial fulfilment of the degree of Doctor of Philosophy (PhD by Published Work) in the Department of Theatre, Film and Television Studies Donald F McLean Aberystwyth University Investigations into the Emergence of British Television 1926-1936 2 Abstract This Critical Review discusses the significance of the author’s published works and their impact on the history of the emergence of British television between 1926 and 1936. Although events in television within this period have since been well- documented, the related debates have tended to be specialist in scope and restricted to technology-centric or institution-centric viewpoints. Within this period of complex, rapid technological change, the author’s published works introduce the principle of embracing multiple disciplines for comparative analysis. The author’s application of that principle opens up long- established views for further debate and provides a re-assessment of early British television within a broader context. The rewards of this approach are a view of events that not only avoids nationalistic bias and restrictions of a single institutional viewpoint, but also tackles the complex interdependencies of technology, of service provision and of content creation. These published works draw attention to the revolutionary improvements that enabled the BBC’s 1936 service and the re-definition of television, yet also emphasise the significance of the previous television broadcast services. The most important innovation within these works has been the author’s discovery and in-depth study of artefacts from that earlier period. -
