This article draws on the case of Napster's problems with the law to question the organization of information markets. The relation between the institutional frame and technological change highlights the way in which the latter necessarily determines changes in production sectors and in the behaviour of economic agents, sometimes making institutions obsolete. Since information markets are an unstable equilibrium between private incentives and public welfare, it is likely that the norms which previously governed these markets are no longer suited to the goals for which they were established. Consumers find themselves in a contradictory position: while on the one hand they are encouraged by new technological potentialities to change their behaviours, on the other they are made to feel guilty about adopting such behaviours.
