Que mesure-ton quand on mesure l'audience?

Abstract

Audience measurement, as any statistics, is a construction which tries to report reality. It consists in a kind of survey and owes its originality to its economical involvements, since audience results are the distribution key of the advertising revenue and condition the economical viability of most media. If the notion of audience is quite simple ("the part of population exposed to a media"), this "exposition's" definition and the way to survey it are problematical. From which one concludes that a certain amount of agreements, which differ according to the media, to reach a plausible delimitation of audience facts, despite the multiplicity of means thanks to which an individual is likely to come into contact with a media and the constraints inherent to the information collected.
