International Thomson Organization was a development of the commercial empire founded by Lord Thomson of Fleet (Roy Thomson). It was formed in 1978 as a holding company for interests in publishing, travel, and natural resources. Under Roy Thomson's son Kenneth Thomson, ITO sold its natural resources and continued expanding in publishing and media. In 1981, it acquired the publishing operations of Litton Industries.[1] By 1986, International Thomson had acquired business publisher Warren, Gorham & Lamont; legal publishers Callaghan & Company and Clark Boardman; and automotive publishers Ward's.[2] Other publishers acquired include Gale, Mitchell, Thomson & Thomson, Sweet & Maxwell, Chapman & Hall, and Routledge. It included Jane's Information Group focused on spreading information especially military intelligence. In 1989 it joined Thomson Newspapers to become the Thomson Corporation.
