Tim Callahan is out as president of ACNielsen North America, VNU announced Friday. Callahan is leaving Oct. 3 to become CEO of the consumer group at Berwind, a family-owned investment management
company. VNU said the search for a successor to Callahan is underway, and that a new head of ACNielsen North America, responsible for the unit's operations in the United States and Canada, will be
announced shortly. In the interim, Steve Schmidt, president and CEO of ACNielsen and executive vice president of VNU Marketing Information, will assume direct accountability for ACNielsen's U.S.
business, while Pat Gardiner, president of ACNielsen Canada, will continue to oversee the Canadian business, reporting to Schmidt.
