Sturgeon Trout

Theodore Sturgeon (the basis for Vonnegut's Kilgore Trout) wrote a 1956 story called "And Now the News..." about a man who is utterly obsessed by the news. When his wife secretly disables the TV and the radio, his mind goes blank. He can't even read anymore! He leaps into his car and drives far into the mountains and becomes a recluse artist on the edge of a cliff. Until the infamous last sentence.
