According to FUNKTIONARY:

The Spectacle - a constructed reality; the concrete inversion of life; via the autonomous movement of the apparently non-living. 2) the mirrorization of the noumenon into the phenomenal universe without understanding or overstanding it as such an objectivization in duality. The Spectacle is not a collection of images but a social relation among people mediated by images. The Spectacle is a theoretical construct—a tool for explaining many things about society; how people live vicariously through the dominant images of production, consumption and power relations. It is the thoughtfofms in which people create, contemplate and consume mediated by images of what-life-is, so that they will forget how to live radically for themselves. It is the totality of images and illusions that alienate people from living, its the primary production of modern societies. It is ideology materialized. It is the social relations that are mediated by the mass media; it is what makes people apathetic and reduces them to inactivity. It is what prevents people from realizing what their collective problems are and dissolving them. It is what perpetually absorbs people into activities that prolong their misery. It is the mediated stream of unreality that channels desire-energy against itself, producing a separate world, a pseudo-world apart form one's self-history—from all those powerful institutions of Self-actualization. It is what motivates people to live a pseudo-life in submission to products and machines, basking passively in the acceptance of oppression, to blindly do what is manifestly against their own self-interest, to pollute the land they love and the air they breathe—it is a fundamental sickness of modern societies superimposed over and aided by the "Rolebots" (clones and drones) of Corporate State. It is the mass media and the propaganda from the pure war machine and the military prison industrial police state complex.
