Writer's Digest was established in 1920 under the name Successful Writing , first issue, December. It changed name to Writer's Digest with the March 1921 issue. By the late 1920s, it shifted emphasis more from literary-quality writing to the rapidly growing pulp magazine field, which offered the widest opportunities to freelance writers. An important feature from 1933 forward was the New York Market Letter, edited by Harriet Bradfield , which gave timely updates on editor needs in the magazine field. As the pulp field collapsed in the 1950s, Writer's Digest shifted emphasis to famous writers and quality fiction.
