The Globalization of Advertising draws upon previously unpublished research to unpack the contemporary structure, spatial organization and city geographies of global advertising agencies. The book demonstrates how teamwork in contemporary advertising agencies, intra-organizational power relations and the distribution of organizational capabilities all define how global agencies operate as transnationally integrated organizations. This in turn allows understanding to be developed of the role of the offices of global agencies located in the three case study cities, Detroit, Los Angeles and New York. The role of these three cities as preeminent markets for advertising in the USA is shown to have changed radically over recent years, experiencing both growth and decline in employment as a result of their position in global networks of advertising work; networks that operate in the context of a changing US economy and the rise of new and emerging centres of advertising in Asia and South America.
