This thesis examines the current polarization of news media, specifically written journalism, either in newspapers or on news websites. Americans increasingly get their news from polarized sources, and that is leading to a large divide in information. This issue is also exacerbated by political idealogy. Furthermore, I explore how the traditional business model of advertising-based revenue is leading to more polarized news coverage. To combat this, I offer interventions for news organizations, including the importance of journalistic ethics and the possibility of more news organizations transferring to nonprofit status, which has gained traction in recent years. Access to accurate news and information is essential in a functioning democracy, and if polarization and issues in news continue, it will be harmful to America as a whole.
