In our times changes occur so rapidly that our modes of reading even more than our modes of analysis risk being inadequate, or in any case risk lagging behind. If we wish to analyze relations between the arts and the media, the danger is in fact that we will limit ourselves to established notions or even to stereotypes which are commonly accepted by the general public. Even for persons with some awareness, information remains lacunary. Moreover, like the experts, or those who pass for such, it seems that it is difficult for them to avoid a personal conception, implicit or avowed, which does not fail to influence their judgement. This is almost always the case when the matter of art is raised, even if we take the precaution of placing the term in the plural. Whether one wishes to or not, there is hardly an example where certain preferences do not make themselves known. If it is easy to reach agreement with regard to the facts, it is less easy to agree on their interpretation, especially when values are at stake. Hence the necessity to proceed by different steps and explanations to explain the relationships between arts and the media.
