Media history is an oddly underdeveloped area. Historians who work in media history are frequently reminded that such work exists at the margins of their discipline, and media does not feature at all in many accounts of political and social history. To take one example, Alastair Davidson’s otherwise impressive From Subject to Citizen: Australian citizenship in the twentieth century (1997) contains one reference to Rupert Murdoch’s citizenship, but none to the role of media in forming the identities of Australian citizens in the twentieth century.
