HarperCollins Publishers LLC was one of the world's largest publishing companies and, alongside Hachette, Holtzbrinck/Macmillan, Penguin Random House, and Simon & Schuster, is part of the "Big Five" English-language publishing companies. Headquartered in New York City, the company is a subsidiary of News Corp. The company name is a combination of Harper & Row—an American publishing company acquired in 1987, itself the result of an earlier merger of Harper & Brothers (founded 1817) and Row, Peterson & Company—and UK publishing company William Collins, Sons (founded 1819), acquired in 1990. The worldwide CEO of HarperCollins is Brian Murray. HarperCollins has publishing groups in the United States, Canada, the United Kingdom, Australia, New Zealand, and India. The company publishes many different imprints, both former independent publishing houses and new imprints.
