Pioneer of the paperback, Penguin was founded in 1935 by Allen Lane, who wanted to offer novels for the price of a pack of cigarettes and published such contemporary writers as Ernest Hemingway and Agatha Christie. Today Penguin has offices in fifteen countries. Where have "Lady Chatterley's Lover" and Salman Rushdie kept company? At The Penguin Group, one of the world's top book publishers (and no stranger to controversial titles). Owned by media giant Pearson, the publisher operates through such imprints as Viking (literary fiction and non-fiction), Puffin (children's books), Dorling Kindersley (reference works), and Rough Guides(travel). Penguin authors include Tom Clancy, Patricia Cornwell, and Nora Roberts.
