This paper uses the organizing concept of “visibility” to investigate how information anc communication technology (ICT) infrastructures have shifted, transformed, and consolidated economic and social power in Western (particularly North American) cities. After surveying the global impacts of IT infrastructures in urban areas, the paper focuses specifically a local example of how wireless internet infrastructure is developed and used in Montreal. Using photographs of telecommunications infrastructure in its everyday viewed context as organizing features, the paper exposes how ICT infrastructure’s banality conceals its important implication in both global and local shifts in economic power, social relationships, and the use of urban space. This “glance over” the economic, social, and physical influence of the internet on urban space concludes with a closer look at the politics of wireless signal provision in Montreal, where a community group has reappropriated ICT infrastruture and competes with leading telecommunication providers for better “visibility” of their wireless signals in politically and socially important areas. The paper is presented in chapters that are intended to stand alone, but which can also be read as sections of a larger work.
