(Beckett, 1971, p.103) We live in a world suffused with information. From our bank records to our lists of friends, from our music collections to the genetic sequence of our bodies—many things which were perceived as physical objects are now widely understood through their information content. Consider music as a straightforward example. There was a time before recording when music couldn’t be separated from people—whether sing- ing or playing an instrument, it was a person or persons doing it. Musical scores provided instructions, but the music required people. Technology broke that tie, and music was available from an object, whether it was a musical box, pianola, a gramophone, tape or a compact disc (CD). The fact that the encoding on a CD was digital was a signifi cant departure from analogue records and tapes, but it wasn’t one that necessarily had an impact on the user. The music was tied to a physical object even if it was a digital CD instead of an analogue record. Today, however, music fl oats free. You can download a fi le and use it wherever you want, transferring between laptop and MP3 player, television (TV) and mobile phone. Or you don’t even bother downloading the fi le, you just listen online whenever you want on your computer at the desk or via your smartphone. Music on a phone draws attention to a consequence of digitisation that has been developing since the telephone network started to use digital tech- nology in the 1980s and which is often referred to as convergence. Origi- nally, it was about the convergence of telecommunications and computing (telephone exchanges became giant computers, and computer data was sent over telephone links), but now all sorts of things converge because they all use digital technology. Taking telephone calls is only a small part of what a mobile phone does now. As well as playing music, it takes photographs, gets you the train timetables and allows you to pay for your parking. There’s little point in enumerating everything you can do because there will be 2 Magnus Ramage and David Chapman lots more that can be done with it in only a matter of months, and any- way sooner or later it will probably some different gadget doing all these things—the concept of a ‘mobile phone’ may itself soon be out of date. The message, though, is that more and more of these things are information, and the physical technology that gets them to us is incidental, or at least is conceptually separate from the information. Talk of what can be done with a mobile phone puts the emphasis on the individual, especially as a consumer. That is not the only area in which the focus on information is increasing though. Government documents are replaced by online information, passports are supplemented by biometric data, and movements are tracked by closed-circuit television (CCTV; for good or ill). Many have argued that the Internet will reshape democratic debate, and some evidence can be seen that this is already happening (as discussed by Castells, 2009). Frequently quoted examples include the bot- tom-up nature of the Obama presidential campaign in the United States in 2008 and the organising of the opposition in Iran via Twitter in 2009, although the popular story of transformation through technology in both of these cases has been questioned. Examples such as these lead many to describe our current period as the information age and the information society. Although there is a need to be careful how we interpret these sentiments and the conclusions that we draw from them, at the very least, we need to explore what is behind them. In particular, it is important to decipher what people are talking about when they refer to ‘information’, since it is far from obvious.
