  Wu, T.: ¬The master switch : the rise and fall of information empires.4. printing.
  New York : Knopf, 2011. X, 366 S.
  ISBN 978-0-307-26993-5
  (A Borzoi book)
  
  Abstract: In this age of an open Internet, it is easy to forget that every American information industry, beginning with the telephone, has eventually been taken captive by some ruthless monopoly or cartel. With all our media now traveling a single network, an unprecedented potential is building for centralized control over what Americans see and hear. Could history repeat itself with the next industrial consolidation? Could the Internet-the entire flow of American information-come to be ruled by one corporate leviathan in possession of "the master switch"? That is the big question of Tim Wu's pathbreaking book. As Wu's sweeping history shows, each of the new media of the twentieth century-radio, telephone, television, and film-was born free and open. Each invited unrestricted use and enterprising experiment until some would-be mogul battled his way to total domination. Here are stories of an uncommon will to power, the power over information: Adolph Zukor, who took a technology once used as commonly as YouTube is today and made it the exclusive prerogative of a kingdom called Hollywood . . . NBC's founder, David Sarnoff, who, to save his broadcast empire from disruptive visionaries, bullied one inventor (of electronic television) into alcoholic despair and another (this one of FM radio, and his boyhood friend) into suicide . . . And foremost, Theodore Vail, founder of the Bell System, the greatest information empire of all time, and a capitalist whose faith in Soviet-style central planning set the course of every information industry thereafter. Explaining how invention begets industry and industry begets empire-a progress often blessed by government, typically with stifling consequences for free expression and technical innovation alike-Wu identifies a time-honored pattern in the maneuvers of today's great information powers: Apple, Google, and an eerily resurgent AT&T. A battle royal looms for the Internet's future, and with almost every aspect of our lives now dependent on that network, this is one war we dare not tune out. Part industrial exposé, part meditation on what freedom requires in the information age, The Master Switch is a stirring illumination of a drama that has played out over decades in the shadows of our national life and now culminates with terrifying implications for our future.

  DeNardis, L. (Hrsg.): Opening standards : the global politics of interoperability.
  Cambridge, Mass. : MIT Press, 2011. xv, 255 S.
  ISBN 978-0-262-01602-5
  (Information society series)
  
  Abstract: Openness is not a given on the Internet. Technical standards--the underlying architecture that enables interoperability among hardware and software from different manufacturers--increasingly control individual freedom and the pace of innovation in technology markets. Heated battles rage over the very definition of "openness" and what constitutes an open standard in information and communication technologies. In Opening Standards, experts from industry, academia, and public policy explore just what is at stake in these controversies, considering both economic and political implications of open standards. The book examines the effect of open standards on innovation, on the relationship between interoperability and public policy (and if government has a responsibility to promote open standards), and on intellectual property rights in standardization--an issue at the heart of current global controversies. Finally, Opening Standards recommends a framework for defining openness in twenty-first-century information infrastructures. Contributors discuss such topics as how to reflect the public interest in the private standards-setting process; why open standards have a beneficial effect on competition and Internet freedom; the effects of intellectual property rights on standards openness; and how to define standard, open standard, and software interoperability.

  Fuller, M.: Media ecologies : materialist energies in art and technoculture.
  Cambridge, MA : MIT Press, 2005. x, 265 S.
  ISBN 0-262-06247-X
  (Leonardo)
  
  Abstract: In Media Ecologies, Matthew Fuller asks what happens when media systems interact. Complex objects such as media systems - understood here as processes, or elements in a composition as much as "things" - have become informational as much as physical, but without losing any of their fundamental materiality. Fuller looks at this multiplicitous materiality - how it can be sensed, made use of, and how it makes other possibilities tangible. He investigates the ways the different qualities in media systems can be said to mix and interrelate, and, as he writes, "to produce patterns, dangers, and potentials." Fuller draws on texts by Felix Guattari (and his "serial collaborator" Gilles Deleuze) as well as writings by Friedrich Nietzsche, Marshall McLuhan, Donna Haraway, Friedrich Kittler, and others, to define and extend the idea of "media ecology." Arguing that the only way to find out about what happens when media systems interact is to carry out such interactions, Fuller traces a series of media ecologies - "taking every path in a labyrinth simultaneously," as he describes one chapter. He looks at contemporary London-based pirate radio and its interweaving of high- and low-tech media systems; the "medial will to power" illustrated by "the camera that ate itself"; how, as seen in a range of compelling interpretations of new media works, the capacities and behaviors of media objects are affected when they are in "abnormal" relationships with other objects; and each step in a sequence of Web pages, "Cctv - world wide watch," that encourages viewers to report crimes seen via webcams. Contributing to debates around standardisation, cultural evolution, cybernetic culture, and surveillance, and inventing a politically challenging aesthetic that links them, Media Ecologies, with its various narrative speeds, scales, frames of references, and voices, does not offer the academically traditional unifying framework; rather, Fuller says, it proposes to capture "an explosion of activity and ideas to which it hopes to add an echo."
  
  Anmerkung: Rez. in: JASIST 58(2007) no.8, S.1222 (P.K. Nayar): "Media ecology is the intersection of information and communications technology (ICTs), organizational behavior, and human interaction. Technology, especially ICT, is the environment of human culture today-from individuals to organizations, in metropolises across the world. Fuller defines media ecology as "the allocation of informational roles in organizations and in computer-supported collaborative work" (p. 3), a fairly comprehensive definition. Fuller opens with a study of a pirate radio in London. Adapting thinkers on media and culture-Stuart Hall, J. F. Gibson's ecological psychology, Deleuze and Guattari figure prominently here. Exploring the attempted regulation of radio, the dissemination into multiple "forms," and the structures that facilitate this, Fuller presents the environment in which "subversive" radio broadcasts take place. Marketing and voices, microphones, and language codes all begin to interact with each other to form a higher order of a material or "machinic" universe (Fuller here adapts Deleuze and Guattari's concept of a "machinic phylum" defined as "materiality, natural or artificial, and both simultaneously; it is matter in movement, in flux, in variation, matter as a conveyer of singularities and traits of expression," p. 17). Using hip-hop as a case study, Fuller argues that digitized sound transforms the voice from indexical to the "rhythmatic." Music becomes fundamentally synthetic here (p. 31), and acquires the potential to access a greater space of embodiment. Other factors, often ignored in media studies, include the role of the DJs (disk jockies), are worked into a holistic account. The DJ, notes Fuller is a switch for the pirate station, but is also a creator of hype. Storing, transposing, organizing time, the DJ is a crucial element in the informational ecology of the radio station. Fuller argues that "things" like the mobile phone must be treated as media assemblages. Pirate radio is an example of the minoritarian use of media systems, according to Fuller. ; Exploring John Hilliard's 1971 series of photographs, A Camera Recording it Own Condition (7 apertures, 10 speeds, 2 mirrors), Fuller argues that the camera's media ecology consists of the interplay between mathematical, material, and social powers, while demonstrating a medial will to power. Fuller shows how every apparatus is an ensemble of other apparatuses. Thresholds of visibility and disappearance are built into the camera's structure, of its material capacity. When the camera focuses on itself, it is engaged in a cybernetic circuit that brings together forces of form, programs, material structures: in short, a media ecology. Fuller marks out two sets of interconnected and antagonistic relations of force that "make" the camera in this act of recording itself. One, the problematic of the camera working on the condition of being a camera (a machine reflexivity). Second, it mobilizes the constraints and freedoms generated by the correlation of the intensive and extensive qualities embedded within the camera. Fuller expands his exploration of media ecologies by working with multiple "objects": the introduction of an on/off switch in a residential street, BITRadio, "phreaking" of radio broadcasts and others. Perhaps the most argumentative chapter of the book-certainly one of the most lucid ones!-this demonstrates how technology and the dynamics of media systems are appropriated for other, nonofficial purposes. Fuller shows how the "standard object"-a serial element such as an ISO standard shipping container whose "potential" has been stabilized, circumscribes knowledge itself, limiting all other forms of understanding. Standard objects, even as they work with other "forms" define the technicity and organizational frames of systems. ; Moving on to Web pages-Heath Bunting's cctv-world wide watch, where users watching four Webcams are encouraged to report crimes on an HTML form, which is then sent to the nearest police station-Fuller shows how cultural and technological components mesh uneasily in the project. Fuller argues that the "meme" (a kind of replicator that mutates as it passes from person to person or media to media, and works in combination with its immediate environment) or "bit" of identity constitutes a problem for surveillance. Packets of information-often the most common "meme" in Web technology-is, for Fuller, the standard object around which an ecology gets built. Networks check packets as they pass isolating passwords, URLS, credit data, and items of interest. The packet is the threshold of operations. The meme's "monitorability" enables not only dissemination through the network, but also its control. Memes, or what Fuller calls "flecks of identity" are referents in the flows of information-they "locate" and "situate" a user. Fuller's work is full of rich insights, especially into the ways in which forces of power operate within media ecologies. Even when the material/technological object, such as the camera or the Webcam turns in on itself, it is situated within a series of interrelated forces, some of which are antagonistic to the object. This insight-that contemporary media technology works within a field of antagonistic forces too-is Fuller's major contribution. Fuller is alert also to the potential within such force fields for subversion. Pirate radio and phreaking, therefore, emblematize how media ecologies create the context, possibility, and even modalities of political and social protest. Unfortunately, Fuller's style is a shade too digressive and aleatory for us to discover these insights. In his eagerness to incorporate as many theorists and philosophers of media/technology-he moves from Nietzsche to Susan Blackmore, sometimes within the space of a single paragraph-Fuller often takes a long time to get to his contribution to the debate or analysis. The problem, therefore, is mainly with style rather than content, and the arguments would have been perfectly fine if they had been couched in easier forms."

  Braunschweig : Westermann, 1983. 208 S.
  ISBN 3-14-508885-8
  (Westermann aktuell)
  
  Abstract: Die jüngste Entwicklung deutet darauf hin, daß durch eine schnelle Verkableung aller Haushalte schon bald bis zu 36 Fernseh- und Rundfunkprogramme von den unterschiedlichsten Programmgestaltern möglich werden. Dazu kommen zahllose neue elektronische Kommunikationsnetze und -systeme. Diese 'Neuen Medien' werden in der Öffentlichkeit seit Monaten diskutiert, zu wenig und nicht tiefgehend genug, wie wir meinen. Denn durch die Verkabelung und den damit verbundenen Computersatz zum Beispiel kommt auf uns eine völlig neue Kulturlandschaft zu, die tiefgreifende Auswirkungen auf die gesellschaftlichen Strukturen, auf unser aller Leben zur Folge haben wird. Steht uns Orwells optisch-akustische Überwachung ins Haus? Engagierte Schriftsteller und Experten nehmen in diesem Buch Stellung, denken die Fragen, die sich aufdrängen, zu Ende, teilen ihre Betroffenheit und ihre Befürchtungen mit
