Famous quotes containing the word television:
“Photographs may be more memorable than moving images because they are a neat slice of time, not a flow. Television is a stream of underselected images, each of which cancels its predecessor. Each still photograph is a privileged moment, turned into a slim object that one can keep and look at again.”
—Susan Sontag (b. 1933)
