At the same time, and for much the same reason, the newspaper has come to assume a didactic role, functioning as both textbook and teacher for those who have advanced beyond the classroom or whose specialized training has left gaps in their understanding of the complex modern world (6).Considerable variation exists both within and across societies in the extent to which the didactic role of the newspaper has become institutionalized. Outside of the Communist world, where the major role of the press has long been seen as that of instructing a mass readership, the society in which this role is most clearly exemplified is Japan:In no arena is [the penchant for study] more clearly manifested than in the mass media. . . . Newspapers, magazines, and television are expected to convey generous amounts of information. Not only do Japanese spend nwre time reading than their American counterparts-whether it be newspapers, magazines, or books-but a higher proportion of the media they encounter is designed to enhance knowledge and skills (11, pp. 29-30).Like so many features of Japanese social organization, this didactic role of the newspaper is seen by some as an anomalous holdover from the past that James R.
