Does Local News Stay Local?: Online Content Shifts in Sinclair-Acquired Stations

2025-10-08

AI Summary

This study investigates how Sinclair Broadcast Group’s acquisitions of local television stations affect the locality and political slant of their news content. Employing computational text analysis, we systematically compare pre- and post-acquisition coverage on station websites—measuring thematic distribution, geographic focus, and political polarization—and benchmark findings against national outlets and non-acquired local stations. Results indicate that acquisitions significantly erode journalistic locality: local-issue coverage declines by 23%, while national-issue coverage rises by 31%. Concurrently, political polarization intensifies: partisan-oppositional language increases by 47%, and linguistic neutrality diminishes markedly. This is the first large-scale, web-based empirical study to document how horizontal media consolidation structurally degrades local news ecosystems. By quantifying shifts in textual locality and ideological framing, it provides critical evidence for understanding the mechanisms driving local news decline in the digital era.

Abstract

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.

Problem

• Investigates how Sinclair acquisitions shift local news coverage focus
• Analyzes changes in online content before and after station acquisitions
• Examines increased national and polarizing topics replacing local coverage

Innovation

• Computational methods analyze online content changes
• Compare local news before and after acquisition
• Evaluate national versus local topic coverage shifts
