RESUMEN
In June 2015, the U.S. Supreme Court made a landmark decision to legalize marriage for same-sex couples amid nationwide debate and media coverage of this controversial issue. Using a content analysis of newspaper articles and television transcripts (N = 286) from top news outlets, this study examines the frames used in news coverage of same-sex marriage before and after the decision and tone of coverage by frame and medium. Findings suggest that frames and tone differed by medium, with television generally presenting more negative coverage and print more positive coverage. Results also suggest that some coverage frames were more negative than others and that the dominant frames of coverage differed from pre- to post-decision. This study helps improve our understanding of how the public was informed before and after a historic decision and illuminates the differences between frame and tone of coverage by medium, and by medium over time.
