In marketing, publicity is the public visibility or awareness for any product, service, person or organization. It may also refer to the movement of information from its source to the general public, often via the media. The subjects of publicity include people of public recognition, goods and services, organizations, and works of art or entertainment.

Public relations (PR) is the practice of managing and disseminating information from an individual or an organization to the public in order to influence their perception. Public relations and publicity differ in that PR is controlled internally, whereas publicity is not controlled and contributed by external parties. Public relations may include an organization or individual gaining exposure to their audiences using topics of public interest and news items that do not require direct payment. The exposure is mostly media-based, and this differentiates it from advertising as a form of marketing communications. Public relations aims to create or obtain coverage for clients for free, also known as earned media, rather than paying for marketing or advertising also known as paid media. But in the early 21st century, advertising is also a part of broader PR activities.
