Penguin Books

Penguin Books Limited is a British publishing house that was co-founded in 1935 by Allen Lane with his brothers Richard and John. Originally an imprint of publishers The Bodley Head, Penguin became a separate company the following year. Penguin revolutionised publishing in the 1930s with its inexpensive paperbacks, sold through Woolworths and other shops for sixpence, bringing high-quality fiction and non-fiction to the mass market. Its success showed that large audiences existed for serious books. It also affected modern British society through its books concerning politics, the arts and science.
