In 1934, Roy Thomson bought his first Canadian newspaper, the Timmins Press in Ontario, and he didn't stop there. Four years after his death in 1976, Thomson Newspapers' total daily circulation in Canada had passed one million. Two generations later, the family's media presence is set to expand again. In May, Reuters agreed to be taken over by Thomson Corp. for $17.6 billion. If all goes well, the merger will be done by spring 2008, and the combined company, Thomson-Reuters, will unite two of the leading financial information data providers.
