The Thomson Corporation was one of the world's largest information companies. It was established in 1989 following a merger between International Thomson Organisation Ltd (ITOL) and Thomson Newspapers. In 2008, it purchased Reuters Group to form Thomson Reuters. The Thomson Corporation was active in financial services, healthcare sectors, law, science and technology research and tax and accounting sectors. The company operated through five segments (2007 onwards): Thomson Financial, Thomson Healthcare, Thomson Legal, Thomson Scientific and Thomson Tax & Accounting.
Until 2007, Thomson was also a major worldwide provider of higher education textbooks, academic information solutions and reference materials. On 26 October 2006, Thomson announced the proposed sale of its Thomson Learning assets. In May 2007, Thomson Learning was acquired by Apax Partners and subsequently renamed Cengage Learning in July. The Thomson Learning brand was used to the end of August 2007.
Subsequently, on 15 October 2007, Educational Testing Service (ETS) finalized acquisition of Thomson's Prometric. Thomson sold its global network of testing centres in 135 countries, for a reported $435 million. Prometric now operates as a wholly owned subsidiary of ETS.
On 15 May 2007, the Thomson Corporation reached an agreement with Reuters to combine the two companies, a deal valued at $17.2 billion. On 17 April 2008 the new company was created under the name of Thomson Reuters. The chief executive officer of Thomson Reuters is Jim Smith, and the chairman is David Thomson, formerly of the Thomson Corporation. Although it was officially a Canadian company and remained Canadian owned, Thomson was run from its operational headquarters in Stamford, Connecticut, in the United States.
Thomson had grown from a single Canadian newspaper, the Timmins Daily Press, acquired in 1934 by Roy Thomson, 1st Baron Thomson of Fleet, into a global media concern. The Baron acquired his first non-Canadian newspaper the Independent of St. Petersburg, Florida in 1952 and the next year it expanded to the United Kingdom. It once owned several prominent newspapers in the UK, including The Times and The Scotsman, and it owned Scottish Television.
In the 1960s, Thomson's publishing realm expanded further to include Thomson Publication (UK), a consumer magazine and book publishing house, and The Times. In 1965, Thomson Newspapers, Ltd. was formed as a publicly traded company in Canada. Roy Thomson's prolific endeavors in publishing had earned him a hereditary title, Lord Thomson of Fleet. Yet, Thomson's interests moved beyond publishing with the creation of Thomson Travel and acquisition of Britannia Airways in 1965 and 1971, and a foray into a consortium exploring the North Sea for oil and gas. Thomson used its oil profits to buy small newspapers in the United States, starting with the acquisition of Brush-Moore Newspapers in 1967 for $72 million, at the time the largest sale of newspapers.
By the end of the 1970s, Thomson Newspapers' circulation in the United States had surpassed the 1 million mark. The merger of Thomson Newspapers and the International Thomson Organization in 1989 created the Thomson Corporation.
Over the years, the company has withdrawn from its holdings in the oil and gas business, the travel industry and department stores.
In 1978, the acquisition of Wadsworth Publishing provided Thomson with its first entry into specialised information, college textbooks and professional books. (In 2007, Thomson Learning, including the Wadsworth imprint, was sold and renamed as Cengage Learning.)
Starting in the mid-1990s, Thomson invested further in specialised information services (but this time providing them in digital format) and began selling off its newspapers. That was about the time Richard J. Harrington, an accountant, became chief executive officer of the company. One of the first moves came when Thomson spent $3.4 billion to acquire the West Publishing Company, a legal information provider in Eagan, MN.
In recent years, Thomson provided much of the specialised information content the world's financial, legal, research and medical organizations rely on every day to make business-critical decisions and drive innovation. While it remained a publishing company, early and aggressive investment in electronic delivery had become a key company goal.
"Except for its educational division, which still publishes a substantial number of conventional textbooks, Thomson had the good fortune to move into these businesses as customers were demanding electronic delivery of their information," according to a 3 July 2006 article in the New York Times. "In some markets, Thomson was able to move past other players who were more cautious about digital conversion."
Some of Thomson's brands are better known than the company name itself. Its brands include Thomson ONE, Westlaw, FindLaw, BarBri, Pangea3, Physician's Desk Reference, RIA, Tax and Accounting (tax and accounting software and services for Accountants) Creative Solutions, Quickfinder, DISEASEDEX, DrugREAX, Medstat, Thomson First Call, Checkpoint, EndNote, Derwent World Patent Index, SAEGIS, Micropatent, Aureka, Faxpat, OptiPat, Just Files, Corporate Intelligence, InfoTrac, Delphion, Arco Test Prep, Peterson's Directories, NewsEdge, TradeWeb, Web of Science and the Arden Shakespeare. Thomson formerly owned Jane's Information Group. These information sources are produced by the many companies of Thomson, including West Publishing, Thomson Financial, ISI, Thomson Gale, Dialog Corporation, Brookers, Carswell, CCBN, Course Technology, Gardiner-Caldwell, IHI, Lawbook Co, Wadsworth, Thomson CompuMark and Sweet & Maxwell.
In late 2004, the company sold its Thomson Media group to Investcorp. The B2B publishing group, which features such titles as American Banker, National Mortgage News, and the Bond Buyer, is now known as SourceMedia.
In October 2006, the company confirmed it would sell the Thomson Learning market group in three parts. The first part, corporate education and training (NETg), has agreed to be sold to Skillsoft for $285 million. Apax announced its acquisition of Thomson's higher education business on 11 May 2007, for $7.5 billion in cash assets.
Thomson Reuters New Zealand Limited has been publishing and updating information on New Zealand law since 1910, formerly as John Friend Ltd, to Brooker and Friend Ltd, to Brookers, to Thomson Brookers'.
Thomson had divested many of its traditional media assets – or combined them with digital products – and had moved toward a larger reliance on information technology services and products.
On 1 January 2004, Thomson adopted a new accounting standard, which required restatement of all prior periods. The company restated its financial reports accordingly.
Members of the last board of directors of Thomson were as follows: David K.R. Thomson (chairman of the board since 2002), W. Geoffrey Beattie, Richard Harrington, Ron D. Barbaro, Mary Cirillo, Robert Daleo, Steven Denning, Maureen Darkes, Roger Martin, Vance Opperman, John M. Thompson, Peter Thomson, Richard Thomson and John A. Tory.
The Thomson family owned 70% of the company.
"David, my grandson, will have to take his part in the running of the organisation and David's son, too," Roy wrote in his 1975 autobiography. "With the fortune that we will leave to them go also responsibilities. These Thomson boys that come after Ken are not going to be able, even if they want to, to shrug off these responsibilities."
The Thomson family controlled the Thomson Corporation through a family-owned entity, the Woodbridge Company, based in Toronto. (Along with 70% of Thomson Corporation, Woodbridge also owns a 40% stake in CTVglobemedia, which now owns the Globe and Mail daily newspaper in Toronto and CTV, Canada's largest commercial TV network.) David K.R. Thomson and his brother, Peter Thomson, became co-chairmen of Woodbridge after their father's death.
