In September 2009, Pogue’s "New York Times" review of the Snow Leopard Macintosh operating system, a product for which he had also authored a "Missing Manual" book, was the subject of a column by "The Times" Public Editor Clark Hoyt. Hoyt wrote that Pogue’s "multiple interests and loyalties raise interesting ethical issues." Of three ethicists Hoyt consulted, each agreed Pogue's position created a "clear conflict of interest" and placed the paper on "tricky ethical terrain." In response, Pogue posted a statement of ethics on his "Times" Topics page and a disclosure was added to his Snow Leopard review on "The Times" web site.
