International Data Group (IDG, Inc.) is a U.S.-based firm specializing in market intelligence and demand generation within the technology sector. Its core objective is to assist technology enterprises by providing research, data analytics, marketing technologies, and insights that enable long-term business partnerships.
Owned entirely by Blackstone, IDG, Inc. has been under the leadership of CEO Genevieve Juillard since 2023. The executive team also includes IDC President Crawford Del Prete and CFO Tiziana Figliolia.
With its headquarters located in Needham, Massachusetts, IDG, Inc. serves as the parent organization for International Data Corporation (IDC) and Foundry (previously known as IDG Communications).
History
International Data Group originated as International Data Corporation (IDC) in 1964, founded by Patrick Joseph McGovern shortly after his graduation from the Massachusetts Institute of Technology (MIT). Operating out of Massachusetts, the company developed a comprehensive computer installation database and published a newsletter titled "EDP Industry and Market Report," inspired by the Diebold Group’s "ADP Newsletter." Prominent clients such as RCA, Univac, Xerox, and Burroughs utilized IDC’s database. McGovern also contributed to "Computers and Automation," recognized as the first magazine dedicated to computing.
Publisher history
In its third year, McGovern contemplated closing the business but instead launched Computerworld in 1967. This publication evolved from a monthly newsletter into a weekly magazine supported by advertising revenue, forming the cornerstone of IDG’s publishing operations.
IDG expanded internationally in 1969 with the establishment of IDC UK and its initial European publication. By 1974, it introduced Computerwoche in Germany, marking its first fully translated international magazine. Throughout the 1990s, IDG broadened its global footprint to include markets such as Japan, China, the Soviet Union, Vietnam, among others.
The launch of MacWorld in 1984 coincided with the Macintosh computer’s release and featured Steve Jobs on its cover. Entering book publishing in 1991, IDG introduced the For Dummies series beginning with DOS For Dummies, which became a widely successful instructional brand until IDG Books (later Hungry Minds) was acquired by John Wiley & Sons in 2001.
By 2007, IDG discontinued the print edition of InfoWorld U.S., transitioning entirely to a digital format that signaled its shift toward online media.
Events, Research & Technology Marketing
During the 1970s and 1980s, IDG diversified into event management and research services. It created the Computer Caravan trade show in the United States, covering nine cities over an 11-week period, which expanded to Europe by 1972. In the 1980s, IDC introduced IDC Predictions, establishing a dedicated technology research and analyst division that continues to provide insights into the worldwide tech industry.
The inaugural IDG DEMO Conference was held in 1991 in La Quinta, California, offering companies a venue to present new technologies to consumers, corporate leaders, and investors. This conference was held internationally until 2015 and became renowned for launching products such as Adobe Acrobat, PalmPilot, VMware Virtual Hardware, Netscape, and Salesforce.
By the mid-2000s, IDG had cultivated an extensive collection of print and digital publications, market research offerings, and global trade events. It amassed a database exceeding six million technology buyers and professionals. This resource was utilized starting in 2006 for marketing initiatives via IDG Connect’s demand generation services. In 2010, IDG introduced an innovative advertising concept called the "Nanosite," which functions as a microsite embedded within an advertisement unit.
Ownership Transitions
Following McGovern's passing in 2014, control of the company passed to the Patrick J. McGovern Foundation. This remained until 2017, when China Oceanwide Holdings Group took ownership. Later, in May 2021, Blackstone Inc. acquired IDG, Inc. from China Oceanwide for $1.3 billion.
Corporate Divisions and Brands
IDG, Inc. serves as the holding company for two primary divisions: IDC and Foundry.
International Data Corporation (IDC)
As a fully owned subsidiary of IDG, IDC specializes in delivering market research, advisory solutions, and hosting events focused on IT, telecommunications, and consumer technology markets. Employing more than 2,500 individuals worldwide—including over 1,300 analysts—IDC provides deep expertise on technological developments and industry dynamics.
In 2019, Crawford Del Prete was promoted to president of IDC after previously holding the COO role. IDC broadened its European presence in May 2021 by acquiring Metri, a Dutch IT intelligence consultancy. This acquisition enhanced IDC’s reach within the Benelux region and strengthened its insights into the European IT landscape.
Foundry
Formerly known as IDG Communications, Foundry was a wholly owned subsidiary of IDG, Inc., delivering media and event services alongside marketing technology and intent data solutions tailored for B2B technology marketers. The rebranding to Foundry in February 2022 marked a strategic pivot from traditional publishing toward a focus on data-driven marketing technologies. With a workforce exceeding 1,400 employees operating across more than 140 countries, Foundry expanded its portfolio through acquisitions such as Triblio, Kickfire, Leadsift, and Selling Simplified between 2020 and 2022. These strategic purchases bolstered its integrated marketing technology capabilities and enriched its data offerings by leveraging established media properties to provide insights into global technology purchasing behaviors.
In March 2025, private equity firm Regent LP acquired Foundry.

Foundry managed several editorial brands aimed at technology buyers across over 90 countries. Many of these brands transitioned from print to digital formats while continuing to play a central role in its media and marketing approach:
