Public relations seeks to both inform like journalism and persuade like advertising. It crosses many legal categories such as the First Amendment, contracts, and regulation. Corporate speech rights were not recognized until the 1970s but now corporations have broad protection for political and social issues and moderate protection for commercial speech. The Citizens United Supreme Court case established that corporations can spend on political messages as long as they are not directly associated with a candidate's campaign. Public relations interacts with areas of tort law, contract law, and the media through recording interviews, public actions, types of remarks to the press, and promises of confidentiality.
