History
Penguin Books Ltd. (est. 1935) of the United Kingdom was bought by Pearson Longman in 1970. In 1975, Penguin acquired the American hardcover firm Viking Press. In 1986, Penguin acquired the New American Library, a mass-market paperback publisher. In 1995, Penguin acquired the independent publisher Donald I. Fine.
Penguin Group (USA) Inc. was formed in 1996 as a result of the merger between Penguin Books USA and the Putnam Berkley Group after Penguin acquired Putnam Berkley from MCA. The newly formed company was originally called Penguin Putnam Inc., but, in 2003, it changed its name to Penguin Group (USA) Inc. to reflect the parent Pearson PLC's grouping of all the Penguin companies worldwide under the supervisory umbrella of Pearson's own Penguin Group division.
The different Penguin companies use many imprints, many of which used to be independent publishers. Penguin Group (USA) Inc. also operates its own speaker's bureau that books speaking engagements for many of the publisher's authors. In 2011, the online writing and publishing community Book Country was launched as a subsidiary of Penguin Group USA.
On 11 April 2012, the United States Department of Justice filed United States v. Apple Inc., naming Apple, Penguin, and four other major publishers as defendants. The suit alleged that they conspired to fix prices for e-books and weaken Amazon.com's position in the market in violation of antitrust law. In December 2013, a federal judge approved a settlement of the antitrust claims, in which Penguin and the other publishers paid into a fund that provided credits to customers who had overpaid for books due to the price-fixing.
