The power of the press to shape the informational landscape of a population is unparalleled, even now in the era of democratic access to all information outlets. However, it is known that news outlets (particularly more traditional ones) tend to discriminate who they want to reach, and who to leave aside. In this work, we attempt to shed some light on the audience targeting patterns of newspapers, using the Chilean media ecosystem. First, we use the gravity model to analyze geography as a factor in explaining audience reachability. This shows that some newspapers are indeed driven by geographical factors (mostly local news outlets) but some others are not (national-distribution outlets). For those which are not, we use a regression model to study the influence of socioeconomic and political characteristics in news outlets adoption. We conclude that indeed larger, national-distribution news outlets target populations based on these factors, rather than on geography or immediacy.

了解新闻媒体的受众群体定位模式

即使在当今民主访问所有信息渠道的时代，新闻界塑造人口信息格局的力量也是无与伦比的。但是，众所周知，新闻媒体（尤其是传统的新闻媒体）往往会歧视他们想要联系的人以及将谁留在一边的人。在这项工作中，我们尝试使用智利的媒体生态系统来阐明针对受众的报纸定位方式。首先，我们使用重力模型来分析地理位置，以此来解释受众群体可及性。这表明某些报纸的确受地理因素的驱动（主要是当地新闻机构），而另一些报纸却不受地理因素的驱动（国家发行机构）。对于不是这样的人，我们使用回归模型来研究社会经济和政治特征对新闻媒体采用的影响。
