Surveillance capitalism is a distinct logic of capitalist accumulation in the “Internet Century”, where users’ data are collected and aggregated to predictions that, sold to the highest corporate bidder, are used to customize advertisements and coupons. Through the aggressive accumulation of behavioral surplus data, surveillance capitalists possess predictive intelligence about hundreds of millions of users; a power sought after by commercial, national security, and political actors. Surveillance capitalism, in its urgency for ever-expanding markets and increasing revenues, recognize the profitable business in mass surveillance and political campaigning. Thus, it acts accordingly. The purpose of this essay is to examine the expression of surveillance capitalism in two areas: the surveillance-industrial complex and political campaigning online. These are then analyzed through an ideal liberal democratic model. It is concluded that surveillance capitalism poses significant threats to liberal democracy due to increased surveillance in citizens’ everyday life and the use of ‘Big Data’ to achieve objectives unknown/unconsented to by users.
