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 corpocracy, examining the way in which the management of the ‘public mind’ has become central to how society is usurped and 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 the damage to corporate image; while analysing the tools public relations professionals use to shift public perceptions.
