NEW YORK -- Media conglomerate News Corp. (NWSA) is set to appoint Robert Thomson, a veteran journalist and the managing editor of The Wall Street Journal, as the CEO of its new, as-yet-unnamed publishing company, according to a report in the Journal.The paper cited unnamed "people familiar with the matter." News Corp. did not respond to a request for comment Saturday. Thomson is also editor in chief of Dow Jones, the News Corp. division that includes the Journal and a financial news service. News Corp. said this summer that it will split into two public companies, one for its newspaper and book publishing business and the other for its fast-growing movie and TV operations. Rupert Murdoch, whose family controls the New York-based conglomerate, will be chairman of both companies.
