Peter Weibel: On the History and Aesthetics of the Digital Image, 1984
"The digital image which allows one to intervene in each section of the picture surface as freely as the artist can in the canvas to form each portion of the picture as one wishes does not just emancipate the art apparatus from its torturous and constricting mechanics but also liberates our thinking in images par excellence from its many constraints. Thus the digital image is the first real foreboding of the "liberated image" like the digital sound of "liberated sound" the program of which was set down at the turn of the century. The art of the twentieth century has undertaken the emancipation of the image in two phases. In the first half of the century with Futurism, Cubism, Cubofuturism, Suprematism, Dadaism, Surrealism, etc. In the second phase with Action Painting, Fluxus, Happening, Pop Art, Kinetism, Op-Art, Ambiente, Arte Povera, actions, performances, etc."
