IDG Communications last month named a new U.S. CEO, Michael Friedenberg, and worldwide president, David Hill, to succeed Bob Carrigan, who is leaving his job as CEO of IDG Communications worldwide after five years in the position. Carrigan will join Dun & Bradstreet on Oct. 7 as president-CEO.
Friedenberg joined IDG in July 2005 as president-CEO of its CXO Media subsidiary, which evolved into the IDG Enterprise unit that comprises all the company's b-to-b-focused media and event brands, including CIO, the CIO Executive Council, Computerworld, DEMO, InfoWorld, ITWorld and Network World.
He was named president-CEO of IDG Enterprise upon its formation in early 2009. Prior to joining IDG, he was VP-publisher of the InformationWeek Media Network, part of the former CMP division of UBM.
In his new position, Friedenberg adds to his IDG Enterprise responsibilities oversight of IDG's Consumer & SMB division, which includes the Macworld, PCWorld and TechHive brands; the IDG TechNetwork (in the U.S.), a digital ad network of independent IT websites and blogs; and IDG World Expo, producer of such technology-focused trade shows, conferences and events as the Electronic Entertainment Expo, Enterprise MobileNext, Game Marketing Summit and Macworld/iWorld.
Hill joined IDG in 1986. Prior to assuming his role as world-wide president of IDG Com-mun-ications, he was president-CEO of IDG International Publishing Services, where he was responsible for international business development and global editorial operations. He now picks up IDG's corporate services, global sales and international media operations in 97 countries.
