Measurement of informative pluralism in Chilean TV: proposal and results of application of a multidimensional analysis instrument
Abstract
The article presents a multidimensional proposal for measuring informative pluralism in different open TV programs: newscasts, morning shows and opinion and debate programs, as well as the results of its application in the Chilean context. For this, a 6-dimensional instrument is proposed: diversity, editoriality, concentration, ownership, perception and scope. The hypothesis is that an adequate measurement of television pluralism requires different dimensions of analysis, which include aspects of programming, audiences and television as a market. After being tested with three different samples over time, the application of the instrument results in low pluralism in the programs analyzed, which is expressed in the homogeneity of content (topics, sources, political parties), in a context of high concentration of the audience and advertising in the channels with the worst score. These findings raise questions and proposals for the regulatory institutions of the sector in the current scenario of constitutional change.
