Television is altering the meaning of 'being informed' by creating a species of information that might properly be called disinformation. Disinformat… - Neil Postman

"Where people once sought information to manage the real context of their lives, now they had to invent contexts in which otherwise useless information might be put to some apparent use. The crossword puzzle is one such pseudo-context; the cocktail party is another; the radio quiz shows of the 1930's and 1940's and the modern television game show are still others; and the ultimate, perhaps, is the wildly successful "Trivial Pursuit." In one form or another, each of these supplies the answer to the question,"What am I to do with all these disconnected facts?" And in one form or another, the answer is the same: Why not use them for diversion? for entertainment? to amuse yourself, in a game?"

In schools, print shifted the emphasis from oral to written and visual communication. Teachers who had been only partly concerned within instructing their students in how to read became by the mid-sixteenth century concerned with almost nothing else. Since the sixteenth century, the textbook has been a primary source of income for book publishers. Since the sixteenth century, written examinations and written assignments have been an integral part of the methodology of school teaching; and since the sixteenth century, the image of the isolated student who reads and studies by himself, has been the essence of our conception of scholarship. In short, for 400 years Western civilization has lived in what has been characterized as the "Age of Gutenberg." Print has been the chief means of our information flow. Print has shaped our literature and conditioned our responses to literary experience. Print has influenced our conception of the educational process. But ...print no longer "monopolizes man's symbolic environment," to use David Riesman's phrase. That monopoly began to dissolve toward the middle of the nineteenth century, when a more or less continuous stream of media inventions began to make accessible unprecedented quantities of information and created new modes of perception and qualities of aesthetic experience. ...1839 ...Daguerre developed the first practical method of photography. In 1844, Morse perfected the telegraph. In 1876, Bell transmitted the first telephone message. A year later, Edison invented the phonograph. By 1894, the movies had also been introduced. A year after that, Marconi sent and received the first wireless message. In 1906, Fessenden transmitted the human voice by radio. In 1920, regularly scheduled radio broadcasts began. In 1923, a picture was televised between New York and Philadelphia. In that same year, Henry Luce and Briton Hadden created a totally new idea in magazines with Time. In 1927, the first "talkie" appeared; and in 1923, Disney's first animated cartoon. In 1935, Major E. H. Armstrong developed the FM radio. In 1936 came Life magazine. In 1941, full commercial television was authorized. These are just some of the inventions that form a part of the "communications revolution" through which we are all living. To these, of course could be added the LP record, the tape recorder, the comic strip, the comic book, the paperback book. ...the point here is ...that the perceptual-cognitive effects on us of the form of these new languages be understood.

Remember: in order for a perception to change one must be frustrated in one's actions or change one's purpose.
