Sinclair收购后，地方新闻站更关注全国性议题，本地内容减少。
Does Local News Stay Local?: Online Content Shifts in Sinclair-Acquired Stations
- 通过计算方法对比收购前后网页内容变化
- 全国性议题报道频率上升，本地议题减少
- 适合关注媒体生态与信息传播的研究者
地方新闻台常被视为非政治化信息的可靠来源，尤其涵盖居民关心的本地议题。由于其可信度高，观众极易受其报道影响。辛克莱广播集团在过去十年收购了多家地方新闻台。本文通过计算方法，分析这些新闻台在被辛克莱收购前后，网络内容的变化，并与全国性新闻媒体对比。结果表明，收购后地方新闻台对全国性议题的报道频率显著上升，而对本地议题的关注明显减少，且对具有争议性的全国性话题报道增多。
原文摘要 · Abstract (English)
Local news stations are often considered to be reliable sources of non-politicized information, particularly local concerns that residents care about. Because these stations are trusted news sources, viewers are particularly susceptible to the information they report. The Sinclair Broadcast group is a broadcasting company that has acquired many local news stations in the last decade. We investigate the effects of local news stations being acquired by Sinclair: how does coverage change? We use computational methods to investigate changes in internet content put out by local news stations before and after being acquired by Sinclair and in comparison to national news outlets. We find that there is clear evidence that local news stations report more frequently on national news at the expense of local topics, and that their coverage of polarizing national topics increases.
