News Corporation, doing business as News Corp, is an American mass media and publishing company headquartered at 1211 Avenue of the Americas in Midtown Manhattan, New York City. The company was formed on June 28, 2013, as a spin-off of the first News Corporation, whose legal successor was 21st Century Fox, which held its media and entertainment assets. Operating across digital real estate information, news media, book publishing, and cable television, News Corp's notable assets include: Dow Jones & Company, which is the publisher of The Wall Street Journal; News UK, publisher of The Sun and The Times; News Corp Australia; REA Group, operator of realestate.com.au and realtor.com; and book publisher HarperCollins. After News Corp announced its plan to split publicly on June 28, 2012, they had planned for it to be a necessary change in order to prioritize the separate needs of each company. Since they were going to be separate companies, each having its own team, it was supposed to make both companies more efficient relative to market changes.
