History

IDC was founded by Patrick Joseph McGovern in Massachusetts in 1964. At the outset, the company produced a computer installation data base and published a newsletter, "EDP Industry and Market Report". Companies like Univac, Xerox and Burroughs paid IDC for the research. After three years, an expanding IDC was grossing US$600,000.[2]

McGovern became engaged by the concept of publishing, after IDC research showed a lack of knowledge among computer systems managers of computer industry news and product developments. He consequently launched Computerworld in 1967, which was a continuation of the monthly newsletter, published weekly instead of monthly, in a different format, with advertising, which became a cornerstone of IDG's subsequent publishing arm.[2]

IDC has had major slips in forecasts. In 2011, IDC predicted Windows Phone to overtake iPhone in market share, but in reality Windows Phone is almost dead.[3]
