Summary

A study by Miriam Wanner, Sophia Hager, and Anjalie Field, presented at the Seventh Workshop on Natural Language Processing and Computational Social Science in July 2026, investigates how local news content changes after acquisition by the Sinclair Broadcast Group. Analyzing YouTube content from local news stations, the researchers employed topic modeling, log-odds ratios, and word embedding analyses. Their findings indicate that stations acquired by Sinclair report more frequently on national news, reducing coverage of local topics. Furthermore, these stations show an increase in their coverage of polarizing national topics. This research, detailed across pages 37–82 of the proceedings, associates Sinclair's acquisitions with a shift towards nationalized and more polarized news content, potentially increasing political polarization among local news viewers.

Key takeaway

For media analysts and researchers evaluating news content integrity, this study highlights a critical shift. You should scrutinize online content from local news stations, especially those acquired by large broadcast groups like Sinclair, for increased nationalization and political polarization. Your analysis should focus on the balance between local and national topics to identify potential impacts on community information access and political discourse.
