“Hans Haacke's "Visitor's Profile" encouraged visitors to interact with a computer by inputting personal information, which was then tabulated to output statistical data on the exhibition's audience. Such demographic research - as art - opened up a critical discourse, following Foucault and others, on the exclusivity of cultural institutions and their patrons, revealing the myth of public service as a thin veneer justifying the hierarchical values that reify extant social relations. Similarly, "Interactive Paper Systems" by Sonia Sheridan, engaged museum-goers in a creative exchange with the artist and 3M's first commercially available color photocopying machine, dissolving conventional artist-viewer-object relations. In "The Seventh Investigation (Art as Idea as Idea)" Joseph Kosuth utilized multiple forms of mass media and distribution (a billboard, an newspaper advertisement, a banner, and a museum installation) to question the conceptual and contextual boundaries between art, philosophy, commerce, pictures, and texts.”
