David Joselit - Feedback: Television against Democracy
There are plenty of scientific facts which testify to the pervasiveness of television, and to the ease with which it affects our consciousness, creating what the author defines as the "image ecology". He focuses on the postwar media art, especially the early video art, not scrutinizing every single major artist of that time, but constructing an analysis of the whole system (a "symbiotic" one he states).
