NEW YORK  - The New York Times backed up its push for a digital future Tuesday by naming Mark Thompson, the outgoing director general of the BBC, as the paper’s new president and chief executive. The Times issued a statement saying: “BBC Director-General Mark Thompson will become its next president and CEO. He will also become a member of the company’s board of directors.” Thompson, 55, will start work in November. The Times, which is America’s most prestigious newspaper as well as a growing online news power, said it had recruited Thompson for his ability to help develop non-traditional news products.
