The Situationist text.
From Wikipedia:
“Alienation, Debord postulated, could be accounted for by the invasive forces of the 'spectacle' - "a social relation between people that is mediated by images". Debord's analysis developed the notions of "reification" and "fetishism of the commodity" pioneered by Karl Marx and Georg Lukács. This analysis probed the historical, economic and psychological roots of 'the media'. Central to this school of thought was the claim that alienation is more than an emotive description or an aspect of individual psychology: rather, it is a consequence of the mercantile form of social organization which has reached its climax in capitalism.”
Guy Debord published his works with an anti-copyright notice, which the translator, Ken Knabb has preserved. I found the book on Ken Knabb’s website

which also contains a number of other Situationist texts. The same translation is also available at Wikisource.
