International Data Group, Inc. (IDG) is an American technology, media, research, event management, and venture capital organization. IDG evolved from International Data Corporation (IDC) which was formed in 1964 in Newtonville, Massachusetts, by Patrick Joseph McGovern, and his friend Fred Kirch. IDC is now a subsidiary of IDG. There is an international parent company (located in Boston), with several publications. The publications are produced on a national level in each country. ==Business== IDG's subsidiary IDG World Expo produces 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 cities such as New York, Beijing, Amsterdam 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. 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「International Data Group」の詳細全文を読む スポンサード リンク
