Kinescopes
"Our history will be what we make it. And if there are any historians about fifty or a hundred years from now, and there should be preserved the kinescopes for one week of all three networks, they will there find recorded in black and white, or perhaps color, evidence of decadence, escapism and insulation from the realities of the world in which we live."
-Edward R. Murrow,
Speech to the Radio and Television News Directors Association (RTNDA) convention in Chicago (October 15, 1958)
