ニュース報道におけるメディア間の共振性の検証

抄録

The concept of inter-media consonance is defined as converging tendencies in reporting of the same issues by different news media.Noelle-Neumann and Mathes (1987) hypothesized that this phenomenon should occur at three levels : agenda-setting, focusing, and evaluation.This article attempts to explore how far the consonance phenomenon is detected in Japanese news media. Five nightly TV news programs and two national newspapers were selected for the content analysis. The results shows that : 1) the issue agenda of the media outlets were quite similar in content in general and in election news ; 2) the focal aspects of the main election issues (of the 1998 Upper House election) were also similar among the different news outlets ; and 3) inter-media consonance, however was not confirmed at the evaluation level.
