The Machine Stops by E. M. Forster
Originally published in The Oxford and Cambridge Review, Archibald Constable & Co., Ltd, London, November 1909
This story "set in a world where humanity lives underground and relies on a giant machine to provide its needs, predicted technologies similar to instant messaging and the Internet." (Wikipedia)
David Suisman's Selling Sounds, describes this "machine-dominated subterranian dystopia," as a place "where music is available everywhere via music-tubes and the experience of life on earth's surface is captured and preserved through phonograph records and movies." (1)
