Introduction
This introductory chapter defines ‘news’ and presents the context of colonial Algeria. Using the example of news of the Tunisian invasion of 1881 in Algiers, it shows how news circulated through a variety of media, forming a complex news ecosystem. This ecosystem challenges standard theories of media put forward by scholars from Marshall McLuhan to Benedict Anderson. The introduction then explains the formation of a deeply divided society within colonial Algeria, placing the history of information within the wider historiography on colonial Algeria. The chapter concludes with a consideration of sources for a history of news, explaining how the colonial surveillance archive can form a useful entry point because surveillance was part of the news circulation system.
