BEDFORD, MA, - Interactive Data Corporation (NYSE: IDC) today announced that John Makinson has been elected chairman of the company and that William B. Gauld has been elected a director.

Mr. Makinson has served as chief executive of The Penguin Group since July 2002 and chairman since 2001.  He served as a member of Interactive Data's board of directors in 2000, following its merger with Data Broadcasting Corporation.  Mr. Makinson was finance director of the Pearson group from 1996 to 2002.  From 1994 to 1996, he was managing director of the Financial Times newspaper, after co-founding and running Makinson Cowell, the consulting firm, from 1989 to 1994.  From 1986 to 1989, he held the position of vice chairman of Saatchi & Saatchi's U.S. holding company.

Mr. Gauld is chief information officer for Pearson and a member of its management committee.  He was previously chief information officer of Sony Electronics Inc. and North American liaison for Sony's worldwide ISS management team.  From 1994 to 1999, he was vice president, corporate information, and chief information officer at Textron Inc.  Prior to joining Textron, he served as chief information officer, responsible for information management of General Electric's Electric Distribution and Control business.

Stuart Clark, president and chief executive officer, commented, "I am very pleased that John is rejoining Interactive Data's board and want to extend a warm welcome to both him and Bill Gauld.  Interactive Data has continued to grow in a difficult market environment, and we see good opportunities ahead of us.  John and Bill both bring valuable ability and experience that will help us take our business forward.  I would also like to thank our previous chairman, Stephen Hill, who has provided enormous support to the development of Interactive Data."

Mr. Makinson stated, "I am very happy to be rejoining the board of a company that has achieved so much over the past three years.  Interactive Data's recent listing on the New York Stock Exchange epitomizes the progress it has made since its merger with Data Broadcasting Corporation. I look forward to using my experience to help the company continue its success."

Mr. Makinson succeeds Stephen Hill, while Mr. Gauld replaces Giles Spackman, both of whom resigned to pursue other interests.
