Which of the following is NOT a type of media used in public relations?

In public relations, the various types of media are categorized to better understand how organizations can communicate with their audiences. Earned media refers to publicity gained through promotional efforts other than paid media, generally seen as more credible because it comes from objective sources. Shared media focuses on content that is shared across social networks, emphasizing audience engagement and interaction. Owned media pertains to any content that a company has full control over, such as its website, blogs, and social media profiles.

Regulated media, however, is not a recognized category within the conventional media types in public relations. The term might suggest certain media content is governed by regulations, but it does not fit into the established framework of media types utilized for PR purposes. Therefore, distinguishing regulated media from the primary forms of media - earned, shared, and owned - clarifies why it does not belong to this context.
