Arthur C. Nielsen Jr., Dead At 92
Arthur C. Nielsen Jr., who helped transform the company his father founded into the world's most powerful media and marketing research organization, died Monday. He was 92. Nielsen, who helped diversify Nielsen beyond its original radio and TV ratings, was pushed out after it merged with Dun & Bradstreet Corp. in the 1980s, after which he once quipped that he was the company's "sex consultant," because he said they told him, "We'll call you if we ever need your f***ing advice." Oddly, the current incarnation of the Nielsen Co. issued no statement on his passing.
