Copywriters prepare advertising copy for use by publication or broadcast media, to promote the sale of goods and services. Established writers may work on a freelance basis. They sell their work to publishers, publication enterprises, manufacturing firms, public relations departments, or advertising agencies. Sometimes, they contract with publishers to write a book or article, or to complete specific assignments such as writing about a new product or technique.
Editors frequently write and almost always review, rewrite, and edit the work of writers.
An editor's responsibilities vary depending on the employer and editorial position held. In the publishing industry, an editor's primary duties are to plan the contents of books, technical journals, trade magazines, and other general interest publications. Editors decide what material will appeal to readers, review and edit drafts of books and articles, offer comments to improve the work, and suggest possible titles. Additionally, they oversee the production of the publications. Major newspapers and newsmagazines usually employ several types of editors.
