The company is headquartered in New York City and is a subsidiary of News Corp. The name is a combination of several publishing firm names: Harper & Row, an American publishing company acquired in 1987—whose own name was the result of an earlier merger of Harper & Brothers (founded in 1817) and Row, Peterson & Company—together with UK publishing company William Collins, Sons (founded in 1819), acquired in 1989.
The worldwide CEO of HarperCollins is Brian Murray. HarperCollins has publishing groups in the United States, Canada, the United Kingdom, Australia, New Zealand, India, and China. The company publishes many different imprints, both former independent publishing houses and new imprints.
In addition to the simplified and merged name, the logo for HarperCollins was derived from the torch logo for Harper and Row, and the fountain logo for Collins, which were combined into a stylized depiction of flames atop waves.
Along with the rest of the publishing world, HarperCollins is focused on growing its e-book sales. In the new media realm, HarperCollins publishes digital copies of its books and maintains them in a digital warehouse. HarperCollins has released more than 8,700 e-books, 50 enhanced e-books, and 70 apps. The e-books, as well as certain audiobooks, are available via the company's website, and through online retailers such as Powells.com (from Powells Books) and Fictionwise.
