Berland explores how understandings of space and time, empire and margin, embodiment and technology, and nature and culture are shaped by broadly conceived communications technologies including pianos, radio, television, the Web, and satellite imaging. Along the way, she provides a useful overview of the assumptions driving communications research on both sides of the U.S.-Canadian border, and she highlights the distinctive contributions of the Canadian communication theorists Harold Innis and Marshall McLuhan. Berland argues that electronic mediation is central to the construction of social space and therefore to anti-imperialist critique. She illuminates crucial links between how space is traversed, how it is narrated, and how it is used. Making an important contribution to scholarship on globalization, Berland calls for more sophisticated accounts of media and cultural technologies and their complex “geographies of influence.”
