Haarlem, the Netherlands—Media giant VNU last Wednesday announced that David Calhoun, vice chairman of General Electric Co., has been named chairman-CEO. He succeeds Rob Ruijter, who has served as interim CEO since June and who will continue as VNU’s CFO. In addition to serving as vice chairman of GE, Calhoun was president-CEO of GE Infrastructure, where he was responsible for GE’s aviation, energy, oil and gas, transportation and water units. His appointment comes about three months after a consortium of six private equity firms, called Valcon, bought VNU for about $11 billion and took the company private. Ruijter had replaced Rob Van den Berg, who lost the confidence of shareholders late last year after VNU’s failed attempt to acquire U.S. pharmaceutical research company IMS Health.
