Agenda y uso de fuentes en los titulares y noticias centrales de los medios informativos chilenos. Un estudio de la prensa impresa, online, radio y televisión1

Abstract

Through a content analysis of headlines and central news of the main Chilean printed and online newspapers, as well as radio and television newscasts, the study describes the degree of homogeneity/diversity of the thematic agenda and the use of sources in different news media platforms. The results reveal a high level of homogeneity, both in the thematic agenda and in the use of news sources among the different types of platforms analyzed, where common professional procedures and values seem to regulate news production in a uniform way, although media with different audience orientations tend to show more heterogeneity among them.
