Content producers are the sources of episode content, like podcast hosts or TV/radio stations. One content producer may create content for multiple shows.
If you have the appropriate permissions, you can view and edit the content producers in your system, as well as create new ones, by clicking the Manage Content tab, then the Content Producers sub-tab. You can see more information about a particular content producer by clicking their name. Use the links in the left navigation bar to view the content producer's shows, details, or metrics (which takes you to the Content Metrics Reports page).
