What he describes is a sort of mashup between a non-interactive internet, teletext and a zooming interface somewhat like the iPhone. The passage takes place when Dr Floyd is on his was to the Moon...
There was plenty to occupy his time, even if he did nothing but sit and read. When he tired of official reports and memoranda and minutes he would plug his foolscap-sized Newspad into the ship's information circuit and scan the latest news reports from Earth. One by one he would conjure up the world's major electronic papers; he knew the codes of the more important ones by heart, and had no need to consult the list on the back of his pad. Switching to the display unit's short-term memory, he would hold the front page while he quickly searched the headlines and noted the items that interested him. Each had its own two-digit reference; when he punched that, the postage-stamp-sized rectangle would expand until it neatly filled the screen, and he could read it with comfort. When he had finished he would flash back to the complete page and select a new subject for detailed examination.
Floyd sometimes wondered if the Newspad, and the fantastic technology behind it, was the last word in man's quest for perfect communications. Here he was, far out in space, speeding away from Earth at thousands of miles an hour, yet in a few milliseconds he could see the headlines of any newspaper he pleased. (That very word 'newspaper' of course, was an anachronistic hang-over into the age of electronics.) The text was updated automatically on every hour; even if one read only the English versions one could spend an entire lifetime doing nothing but absorbing the everchanging flow of information from the news satellites.
It was hard to imagine how the system could be improved or made more convenient. But sooner or later, Floyd guessed, it would pass away, to be replaced by something as unimaginable as the Newspad itself would have been to Caxton or Gutenberg.
There was another thought which a scanning of those tiny electronic headlines often invoked. The more wonderful the means of communication, the more trivial, tawdry or depressing its contents seemed to be. Accidents, crimes, natural and man-made disasters, threats of conflict, gloomy editorials - these still seemed to be the main concern of the millions of words being sprayed into the ether. Yet Floyd also wondered if this was altogether a bad thing; the newspapers of Utopia, he had long ago decided, would be terribly dull.
