While advertising is clearly a visible component of the corporate system, perhaps even more important and pervasive is the often-invisible partner—the public relations industry. Toxic Sludge Is Good For You illuminates this hidden sphere of the corporatocracy, examining the way in which the management of public discourse has become central to how society has been usurped and is controlled by political and economic elites. The film tracks the development of the PR industry from its early efforts to win popular support for World War I, to the role of crisis management in controlling damage to the corporate image, while analysing the tools PR people use to manipulate public perceptions.
