The aim of this book is to clarify how surveillance in informational capitalism can be theorised. This work constructs theoretically founded typologies in order to systemise the existing literature of surveillance studies and to analyse selected examples. It argues that conventional surveillance theories are insufficient for studying surveillance in general and Internet surveillance in particular. In contrast, a typology of surveillance in informational capitalism, which is based on the foundations of a critical political economy approach, allows to systemise and to analyse (online) surveillance in the spheres of production, circulation, and consumption. In conclusion, political recommendations are drawn in order to overcome surveillance in informational capitalism.
