During the 1920s, 1930s and 1940s, Dell was one of the largest publishers of magazines, including pulp magazines. Their line of humor magazines included 1000 Jokes, launched in 1938. From 1929 to 1974, they published comics under the Dell Comics line, the bulk of which (1938–62) was done in partnership with Western Publishing. In 1943, Dell entered into paperback book publishing with Dell Paperbacks. They also used the book imprints of Dial Press, Delacorte Books, Delacorte Press, Yearling Books, and Laurel Leaf Library.
Dell was acquired by Doubleday in 1976, which was itself acquired by Bertelsmann in 1986. Bertelsmann later consolidated Dell with other imprints into Random House.
