A pioneer of children's publishing, John Newbery made children's literature a sustainable and profitable part of the literary market.[25] The History of Little Goody Two-Shoes was published by Newbery in 1765.[25] Founded by Sir Allen Lane in 1935, Penguin Books revolutionised publishing in the 1930s through its inexpensive paperbacks, bringing high-quality paperback fiction and non-fiction to the mass market.[26] Formed in 1940, Puffin Books is the children's imprint of Penguin Books. Barbara Euphan Todd's scarecrow story, Worzel Gummidge, was the first Puffin story book in 1941.[27]
