The growth of transnational communications, most notably the Internet and email, has had a profound impact on social and political interactions across borders. Doreen Massey, a social and political geographer, has written widely about space, with an emphasis on examining relations between actors, rather than the roles that they play. Her research suggests that space can be conceived of as constructed of these relations and, as a consequence, power can be seen to operate at multiple and complex levels. This article examines Massey's work, identifying areas of particular relevance to communications scholars. Massey's thinking is applied to the contemporary communications arena, where her ideas on space and 'power-geometries' offer new insights into how the complexities of transnational relations can be understood.
