Publicist from WikiPedia:

A publicist is a person whose job is to generate and manage publicity for a public figure, especially a celebrity, a business, or for a work such as a book or film. Just like lawyers, most top level publicists work in private practice, handling multiple clients.

In the world of celebrities, unlike agents or managers, publicists typically take a monthly fee for serving a client (whereas agents and managers tend to take a percentage of their client's gross income). Publicists can be at local, regional or national level. They can also have special expertise in areas such as entertainment or literary publicity.

One of the publicist's main function is to generate press coverage on behalf of clients and to serve as the bridge between clients, their public and media outlets. A publicist writes press releases, manages campaigns and performs other public relations functions. It usually takes many years to develop the media contacts, experience and relationships necessary to be an effective publicist.
