According to our book Think Public Relations, Publicity is defined as disseminating planned messages through selected media to further an organization’s interests. Public Relations is defined as the management function that identifies, establishes, and maintains mutually beneficial relationships between an organization and the various publics on whom its success or failure depends. Publicity is part of Public Relations. Publicity effects Public Relations. For example, according to Seth Godin’s blog, if you send out a boring press release, your publicity effort will probably fail, but your PR already has. This is because it is the job of PR firms to form these press releases in order to give a company good publicity. If they fail to do this, they fail at being a PR firm.
PR and publicity are alike though. Both PR and publicity are supposed to spread the word about a company, and are involved with communication and relationships between a company and its publics.
An example of Public Relations is Publicity, because publicity is a characteristic of PR and is something PR professionals must be able to do.
An example of publicity would be a press release, or any form of favorable stories in the news media.
