International Data Group (IDG) is a technology media, research and event management organization. IDG evolved from International Data Corporation which was formed during 1964 in Newtonville, Massachusetts by Patrick Joseph McGovern and a friend, and which is now a subsidiary of IDG.
IDG publishes over 300 magazines in 85 countries and their five global publication product lines – Computerworld/InfoWorld, CIO, Macworld, Network World, and PC World – account for more than 175 of these titles. McGovern has made billions of dollars from the growth of IDG, which has remained a private company.
IDG Books, which was a public company spun off from the privately held IDG, published the popular self help "...For Dummies" books. The "...For Dummies" range was originally limited to computer related fields, but later expanded to include a much wider variety of topics. The series is now published by John Wiley & Sons; IDG Books/Hungry Minds (as IDG Books was briefly renamed before being sold to Wiley in 2001) no longer exists as a separate company.
IDG's subsidiary IDG World Expo produces a variety of large-scale events, such as conventions. These are typically conventions for technology businesses. IDG World Expo runs E for All, Macworld Conference & Expo, and LinuxWorld Conference and Expo.
IDG also has its own international news agency, IDG News Service. It is headquartered in Boston and has bureaus in New York, Washington, San Francisco, Tokyo, Taipei, Beijing, Singapore, Bangalore, Paris, London, Dublin, and Brussels. It provides news, images, video and other editorial content to IDG's web sites and print publications worldwide.
In 2005, several investors, including IDG, attempted to purchase BlogCN. Sohu.com Technology. http://it.sohu.com/20051121/n240767840.shtml. November 21, 2005. Retrieved March 1, 2007.
There is an international mother company (located in Boston), with a few publications. Every country where IDG is located in, the publications are published on a national level, where there is a lot of knowledge for that particular local market.
