Excerpt:
Dow Jones & Company is an American publishing and financial information firm.
The company was founded in 1882 by three reporters: Charles Dow, Edward Jones, and Charles Bergstresser. Like The New York Times and the Washington Post, the company was in recent years publicly traded but privately controlled. The company was led by the Bancroft family, which effectively controlled 64% of all voting stock, before being acquired by News Corporation.
The company became a subsidiary of News Corporation after an extended takeover bid during 2007.^[3] It was reported on August 1, 2007 that the bid had been successful^[4][5] after an extended period of uncertainty about shareholder agreement.^[6] The transaction was completed on December 13, 2007. It was worth US$5 billion or $60 a share, giving NewsCorp control of The Wall Street Journal and ending the Bancroft family's 105 years of ownership.^[7]
In 2010, the company sold 90% of Dow Jones Indexes to the CME Group, including the Dow Jones Industrial Average.
