Unfinished' defines the aesthetic of new media. Internet sites, for example, the emblematic genre of new media, never solidify into a definitive form, they remain ephemeral, patchy,``permanently beta'' (Neff and Stark, 2003, page 3): (1) versions change, systems evolve, applications die. This aesthetic logic of the provisional and transient is also reflected in the organisational practices of new media. In the dizzyingly fluid environment in which new media evolve, organisational practices are driven by the imperatives of bricolage, improvisation, self-organisation, and adaptability.In this theme issue we delve into these organisational dynamics of new media. We share the view that, despite the en masse depreciation of Internet stocks after April 2000, organisational practices generated in and through new media will have a lasting impact (Schultz et al, 2000;Thrift, 2000;. In other words, although with the drastic end of`t he long summer of corporate love'' (Frank, 2000, page 356) new-media firms might have disappeared spectacularly, new-media practices have not. Studying the practices emerging from this``frenzy of capitalist experiment'' (Thrift, 2001, page 430) from different (disciplinary) angles, in our view, yields insights of more general relevance for understanding organisational forms and processes in turbulent environments.The central organisational arena of these practices is the project (Braczyk et al, 1999a, page 6; Heydebrand, 1999, pages 67^69). Of course, projects as`temporary systems' with`institutionalised termination' (Goodman and Goodman, 1976;Lundin and So« derholm, 1995) are not an organisational innovation of new media. They are a long-established routine in industries organised around`one-off' activities such as construction, engineering, shipbuilding, or`old' media such as film (Faulkner and Anderson, 1987;Lundin and Midler, 1998;Winch, 1986). More recently, project organisation seems to have taken hold in a wide range of industries in which it has not previously been part of the canonical repertoire of organisational forms (Ekstedt et al, 1999;Flores and Gray, 2000). This diffusion has been accelerated by codified formulas and routines of planning, budgeting, and managing projects as distinct organisational units (PMI, 1996) which mostly have been set up unambiguously either within or between organisations (Lundin and Midler, 1998). Economic geographies of this type of`managed project' have been examined in a previous Regional Studies special issue (Grabher, 2002a).Although more conventional forms of`managed projects' have also become an essential vehicle for new-media production,`self-organised projects' reflect the genuine emergent character of this field more specifically. In evolving and self-coordinating projects, neither the division of labour between team members nor the coordination of team activities follows traditional management principles (Heydebrand and Miro¨n, 2002). Because design is not compartmentalised but is generalised and distributed throughout the production process...
