Journalism is surely one of society's great institutions. It has long been an important site of knowledge production, allowing audiences to make sense of their world.

Public relations has been using journalism as a means of publicity for nearly a century.

The research looks at Canadian television news through these lenses, as well as through the words of working Canadian journalists.  The interaction of PR and news is examined to understand how news stories get developed, where the content and resources presented in those stories come from, and who is benefiting from changing practices in the newsroom
