“Early in the 1960s, avant-garde composer Nam June Paik began experimenting with the wiring inside his TV. He learned how to manipulate the picture on his screen, bending and warping network broadcasts like free jazz. In 1963, after accumulating and tweaking a dozen more televisions, Paik organised a gallery show in which people were invited to interact one-on-one with his contraptions – an unprecedented experience in an era before video cameras and cable stations.”
