News coverage of the same events is simultaneously driven by homogenizing and heterogenizing influences. In this paper, we assess whether and when conflict news in different media become more similar or dissimilar by analyzing the coverage of the Israeli-Palestinian conflict in 13 leading Israeli, Palestinian, and international media over almost 10 years. We distinguish between drivers of enduring similarity, gradual convergence and temporary (dis-)alignments in the news, and relate them to the detected concept association patterns in over 200,000 news texts. We find a slow, context-dependent convergence trend in the news, and temporary alignments and dis-alignments in interpretation in response to major conflict events. Discussing the underlying, interacting influences, the study highlights implications for investigating current transformations in global journalism.
