This chapter maps out the trajectory of British postmodern fiction in three specific phases: a gradual emergence characterised by slowly increasing textual experimentation in the 1960s and 1970s; a second phase notable for a high level of fictional critique of the political and economic order in the 1980s and 1990s; and a third period in the early twenty-first century, by which point both the techniques and ideas associated with postmodern literature had become so commonplace that they could no longer be considered critically oppositional. In identifying these phases, the chapter departs from Fredric Jameson’s famous suggestion that postmodernism embodies the cultural logic of late capitalism and is therefore completely unable to generate any effective criticism of the dominant ideology of global capitalist societies and shows that at its height British postmodern fiction constituted a genuinely critical form of writing with regard to that ideology.
