Penguin Publishing Group is one of the world's most famous English-language book publishers. Its English book sales rank first in the United Kingdom, Australia, New Zealand, and India, and second in the United States and Canada. Penguin Group publishes a variety of general publications for the English language market, mainly fiction and non-fiction, award-winning literature and children's books, with 30,000 titles in print. DK Publishing Company (Dorling Kindersley), acquired by the group in 2000, has been reorganized and is now the world's largest illustrated reference book publishing company. Penguin Group's global business also continues to grow, and the "Who Moved My Cheese" series, which is familiar to domestic readers, is selling well around the world. The company's goal is to provide customers with "cradle to grave" family books, and its unique illustration style has won the market.
