PC World and Macworld Promote Michael Carroll to SVP/Group Publisher; Paul Zampitella Named Publisher of Macworld

SAN FRANCISCO, CA – APRIL 12, 2007 – Today, PC World and Macworld announced the promotion of two senior level executives, Michael Carroll and Paul Zampitella. Formerly VP/Publisher of PC World Online and Macworld Online, Carroll now assumes the role of SVP/Group Publisher of both PC World, provider of trusted technology advice for readers and buyers, and Macworld, the world's foremost Mac authority. In addition to leading the print and online sales efforts at both media companies, Carroll also oversees Ad Operations, Marketing, and Research. Zampitella moves up from Associate Publisher at Macworld to take on the role of Publisher, leading print sales efforts.

"Michael has been a tireless sales leader over the years," said Colin Crawford, president and CEO of PC World and Macworld. "I look forward to working closely with him and his entire team as we grow the PC World and Macworld brands, offering our clients integrated solutions."

A 19-year IDG veteran, Carroll began his PC World career as an Account Manager. In 1999 he was named Ad Director for Consumer Advertising and Custom Publishing. During this time he launched non-endemic sales efforts bringing in automobile, electronics, and financial advertising for the first-time. In addition, Custom Publishing sales jumped by 150% and outside publishing contracts were secured from CDW, Gateway, and Microsoft, among others. In 2001 he became Associate Publisher for PC World Online, and was promoted to VP/Publisher, Online in 2005. Since 2005, under his direction, online ad revenue increased by over 84%. A native of Keene, New Hampshire, Carroll graduated from Keene State College with a B.S. in Marketing and Management. Carroll now resides with his wife and three children in Massachusetts.

Zampitella's ascension at Macworld began in 2005 when he joined the company as Eastern Online Advertising Manager; in 2006, he was promoted to Associate Publisher. Recently, Zampitella teamed up with IDG World Expo to create the ADC (Apple Developer Connection) Go-To-Market Program which provided low-cost exhibitor packages at the Macworld Conference & Expo for the Apple developer community. The program attracted 48 new exhibitors who otherwise would not have been able to exhibit at the show. In return, the program gave Macworld a chance to build key relationships with Apple. In his new role, Zampitella will work closely with Carroll to evolve Macworld's integrated sales structure.

"Paul's done a tremendous job at Macworld in a very short time," stated Carroll. "I look forward to working with him to build on Macworld's place in the Mac industry, and further enhancing its print initiatives going forward."

Zampitella holds a B.A. in Political Science from Boston College and currently resides in Massachusetts with his wife and two children.
