This article presenting the thematic dossier reminds us that the multiplication of challenges to Silicon Valley is part of a longer history of social mobilization and critical theories regarding information technology and networks. The purpose of the dossier is to review the history of the digital age through the lens of critique. The historiography and sociology of this critique allow us to examine the stages of construction of digital technology as a homogeneous object, despite a multitude of practices, spaces and meanings. They also shed light on the themes attending this development. This introduction presents the main lines of a socio-history of critique of digital technology since the late 1970s, highlighting both the continuity and the renewal of critical motifs from that time, up to the current techlash. On this basis, the dossier proposes analytical tools that testify to the influence of older philosophical and political lineages such as social critique, liberal critique or ecological critique. The study of digital critique thus re-enacts the classical opposition between internal and external critique. To conclude, the article proposes reflection on the “digitizations of critique”.
