The evolution of P2P networks for file exchange: The interaction between social controversy and technical change Authors Jairo Ares Blanco Universitat Oberta de Catalunya Eduard Aibar Puentes Universitat Oberta de Catalunya Keywords: P2P networks, file exchange, social shaping of technology, copyright controversy Abstract Since the irruption of Napster in 1999, Peer-to-Peer computer networks for file exchange have been at the heart of a heated debate that has eventually evolved into a wide social controversy across the world, involving legal, economical, and even political issues. This essay analyzes the effects of this controversy on the technical innovations that have shaped the evolution of those systems. It argues that the usual image of a single two-sided conflict does not account for most of the technical changes involved. P2P entrepreneurs and creators show a wide range of motivations and business strategies—if any—and users are not a monolithic group with a common set of goals and values. As a result, the actual historical evolution of those networks does not follow a simple linear path but a more complex and multidirectional development.Key words: P2P networks, file exchange, social shaping of technology, copyright controversy Author Biographies Jairo Ares Blanco, Universitat Oberta de Catalunya DoctorandInternet Interdisciplinary Institute Eduard Aibar Puentes, Universitat Oberta de Catalunya Professor agregat Estudis d'Arts i Humanitats (UOC, investigador al Internet Interdisciplinary Institute (IN3 -UOC) Downloads PDF (Català) Published 2012-06-26 Issue Vol. 4 (2011) Section Articles License The intellectual property of articles belongs to the respective authors.On submitting articles for publication to the journal Actes d’Història de la Ciència i de la Tècnica, authors accept the following terms:Authors assign to Societat Catalana d’Història de la Ciència i de la Tècnica (a subsidiary of Institut d’Estudis Catalans) the rights of reproduction, communication to the public and distribution of the articles submitted for publication to Actes d’Història de la Ciència i de la Tècnica.Authors answer to Societat Catalana d’Història de la Ciència i de la Tècnica (SCHCT) for the authorship and originality of submitted articles.Authors are responsible for obtaining permission for the reproduction of all graphic material included in articles.SCHCT declines all liability for the possible infringement of intellectual property rights by authors.The contents published in the journal, unless otherwise stated in the text or in the graphic material, are subject to a Creative Commons Attribution-NonCommercial-NoDerivs (by-nc-nd) 3.0 Spain licence, the complete text of which may be found at http://creativecommons.org/licenses/by-nc-nd/3.0/es/deed.en.
