Years before the advent of mobile telecommunications the concept of place as an immobile dimension had been challenged. Consider the studies by Manuel Castells, from his “Crisis, Planning, and the Quality of Life: Managing the New Historical Relationships between Space and Society” (Society and Space, 1983) to the three volumes of The Information Age: Economy, Society and Culture (Oxford: Blackwell, 1996--98); the classic by Joshua Meyrowitz, No Sense of Place: The Impact of Electronic Media on Social Behavior (New York: Oxford University Press, 1985); Doreen Massey's Spatial Divisions of Labour: Social Structures and the Geography of Production (London: Macmillan, 1984, repr. 1995), her "A Global Sense of Place" (Marxism Today, June 1991), as well as Massey and P. Jess, eds., A Place in the World? Culture, Places and Globalization (Oxford: Oxford University Press, 1995); and Saskia Sassen's Globalization and Its Discontents: Essays on the New Mobility of People and Money (New York: The New Press, 1998).

An excellent synthesis of the latest literature on the subject is provided by Masao Kakihara and Carsten Sørensen in their paper "Organisational Knowledge in Mobile Workplaces", presented at the conference Mobilize! Workshop on interventions in the social, cultural and interactional analysis of mobility, ubiquity and information and communication technology, 29-30 May 2001, Cumberland Lodge, Windsor, UK (download: http://is.lse.ac.uk/staff/sorensen ==> "Mobility paper [pdf]").
