AbstractNo presente ensaio tentaremos percorrer seis pistas determinantes na emergência das actuais sociedades da informação. Principiamos esta viagem no momento em que o Homem adquire a habilidade de produzir e partilhar informação. Volvidos alguns milénios é a própria memória humana que adquire um suporte externo: a tecnologia escrita. Séculos decorridos, a tarefa de copiar as obras escritas haveria de se “mecanizar”, por via da prensa de tipos móveis. O século XIX trouxe consigo o telégrafo eléctrico e a possibilidade de transmitir mensagens à distância de forma quase instantânea. No segundo quartel do século XX, os computadores electrónicos haveriam de revolucionar os processos de cálculo e processamento da informação. Finalmente, a Internet proporcionou, em termos teóricos, a democratização no acesso à informação pelas massas.
