A 'cegueira' da rádio deve ser vista como uma mais-valia

«Radio, on the other hand, has an advantage even over the printed text in being entirely non-visual and can thus let as a secondary intellectual medium - one through which we can absorb many if not all forms of information and ideas while being free to do something else. (...) the blindness of radio should be seen as a precious asset» (Crisell a, 2006: 10) 

«(...) if we wish to broadcast informative and analytical material, then having regard to the innate character of radio and television and starting, as it were, with a tabula rasa, we will find it more effective to do so through the blind medium of radio than through the pictorial medium of television.» (Crisell a 2006: 12) 

(com que implicações ao nivel do proprio futuro da rádio? isto significa que ela se deve continuar a centrar no seu elemento sonoro, em detrimento das caracteristicas multimedia? colocar a questão no consumo passivo)
