Whilst discussions of British and American fiction often depend upon binary oppositions (tradition vs. experimentation, etc.), this chapter argues that the longer arc of British postmodern fiction is better understood in less polarising terms that instead reflect the overlaps, migrations, exchanges, and economic realignments that emerging technologies introduced in the late twentieth century. This argument hinges upon reading Martin Amis’s Money as a particularly prescient example of a transatlantic network novel. Amis’s seminal text reconceives the oceanic divide not simply in terms of American financial power, but specifically in terms of developing computer technologies: the chapter argues that Money’s network-inflected conception of space, as well as its signature stylistic and formal innovations, interweave British and American cultural spaces in an exemplary fashion, the legacy of which can be traced through the millennium into major novels that enact British postmodernism’s afterlife by Hari Kunzru, Tom McCarthy, David Mitchell, and Zadie Smith.
