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.[8][9] 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.
