Agree.
Public relations (PR) sources do provide a significant amount of information used in the media today. PR professionals often create and distribute press releases, organize events, and manage communications that serve as primary sources of information for journalists. These activities help to shape narratives and drive news coverage. However, it's also important to recognize that media outlets rely on a variety of sources, including independent reporting, expert interviews, and other forms of research to create a balanced perspective. Therefore, while PR sources are influential, they are part of a broader ecosystem of information that the media draws from.
