I should begin by defining some of the metaphors I use in this paper. By the ‘Gutenberg Galaxy’ I mean the world of print on paper. Thus the ‘PostGutenberg Galaxy’ is its successor, the virtual world of bytes on tape, disk and screen — and especially dispersal in the fibreoptic cables enmeshing the globe and transmitting them everywhere at the speed of light. I also use the term ‘Skywriting,’ for the dissemination of the written word in the PostGutenberg Galaxy is very much like writing it all up in the sky, for everyone to see and to append their own scribblings onto, rather like the serial graffiti in public toilets, except on a galactic scale. Or perhaps a global Hyde Park, with the orations and cat-calls all delivered graphically rather than orally.
