概要	The uses and gratifications survey is the dominant audience-centered method in communication research, asking not what media do to people but what people do with media. Codified by Katz, Blumler, and Gurevitch in 1973, it treats audiences as active agents who select media to satisfy social and psychological needs, and it measures those motives and the rewards obtained through structured self-report scales.	Media richness analysis applies Daft and Lengel's media richness theory to evaluate communication channels by their capacity to carry rich information and to assess how well a channel fits the equivocality of the task at hand. Rooted in organizational communication, it provides criteria — feedback immediacy, multiplicity of cues, language variety, and personal focus — for ranking channels from lean (a memo) to rich (face-to-face) and for diagnosing whether managers and teams are matching channel to message appropriately.
