For example, a freelance writer might be hired to write about a new product. Common employers are publishers, businesses, or public relations and advertising departments or agencies. Some freelance writers create a product, such as a book or article, that they then try to sell to publishers. In these situations, writers were not assigned a topic. Instead they write what they are interested in and hope to find a buyer.
Editors review, rewrite, and edit the work of writers.
Occasionally editors even write. However, they mostly plan the contents and preparation of books, magazines, or newspapers. They decide what will appeal to readers and assign topics to writers. Editors also hire writers, reporters, and other employees. They plan budgets and negotiate contracts with freelance writers.
