Spr\u00e1vcovia informa\u010dn\u00fdch technol\u00f3gi\u00ed tej doby – pis\u00e1ri – mali obrovsk\u00fa cenu. Konzervovan\u00e1 inform\u00e1cia naberala na hodnote.\u00a0Proces spracovania a vyu\u017e\u00edvania inform\u00e1ci\u00ed v \u010do najvernej\u0161ej podobe bol v centre diania. Potreba preda\u0165 \u010falej novoz\u00edskan\u00e9 poznatky naberala na obr\u00e1tkach s roz\u0161irovan\u00edm vedomost\u00ed \u013eudstva.

V tej dobe novoskon\u0161truovan\u00e1 kn\u00edhtla\u010d bola obrovsk\u00fdm posunom. Pred\u00e1vanie inform\u00e1ci\u00ed sa op\u00e4\u0165 zr\u00fdch\u013eovalo.\u00a0\u00a0V \u010fal\u0161ej hist\u00f3rii sa za\u010dali vyv\u00edja\u0165 technol\u00f3gie, ktor\u00e9 najprv nemuseli vyzera\u0165 ako n\u00e1pomocn\u00e9 pre rozvoj prenosu inform\u00e1ci\u00ed. Pr\u00edstroje sa zdokona\u013eovali a t\u00fdm r\u00e1stli mo\u017enosti ich vyu\u017eitia. Revol\u00facia so sebou priniesla telegraf, ktor\u00fd umo\u017enil r\u00fdchly prenos inform\u00e1ci\u00ed na ve\u013ek\u00fa vzdialenos\u0165. V tomto obdob\u00ed sa \u013eudstvu po prv\u00fd kr\u00e1t podarilo prenies\u0165 zvukov\u00fa stopu. T\u00e1to forma spracovania inform\u00e1cie bola fenom\u00e9nom a \u010fal\u0161\u00edm skokom v pred\u00e1van\u00ed inform\u00e1cie. Prv\u00fdm medi\u00e1torom bol telef\u00f3n. R\u00e1dio predsavuje \u010fal\u0161ieho n\u00e1stupcu v zdie\u013ean\u00ed inform\u00e1cie v podobe zvukov\u00e9ho z\u00e1znamu. Samozrejme prenos audio z\u00e1znamu nezastal pri t\u00fdchto dvoch z\u00e1stupcoch.\u00a0V\u00fdvoj spracovania a prenosu inform\u00e1ci\u00ed \u010do najvernej\u0161ie pokra\u010doval v podobe vzniku prv\u00fdch telev\u00edzorov.
