The original incarnation of News Corporation was an American multinational mass media corporation operated and owned by media mogul Rupert Murdoch and headquartered in New York City. Prior to its split in 2013, it was the world's fourth-largest media group in terms of revenue, and News Corporation had become a media powerhouse since its inception, almost dominating the news, television, film and print industries. News Corporation was a publicly traded company listed on NASDAQ. Formerly incorporated in Adelaide, South Australia, the company was re-incorporated under Delaware General Corporation Law after a majority of shareholders approved the move on November 12, 2004. News Corporation was headquartered at 1211 Avenue of the Americas, New York, in the newer 1960s–1970s corridor of the Rockefeller Center complex. On June 28, 2012, after concerns from shareholders in response to its recent scandals and to "unlock even greater long-term shareholder value", founder Rupert Murdoch announced that News Corporation's assets would be split into two publicly traded companies, one oriented towards media, and the other towards publishing. The corporate spin-off formally took place on June 28, 2013; where the present News Corp. was renamed 21st Century Fox and consists primarily of media outlets, while a new News Corp was formed to take on the publishing and Australian broadcasting assets.
