ABSTRACT
The most recent period has seen considerable authority building for business media, which have been part of a concentration process with successive mergers and acquisitions leading to a limited number of large multinational multi-media houses. The four publishers established early Wiley, Harper, Macmillan, and McGraw-Hill have been part of major structural changes during the most recent period. Another important event in the publishing industry related to the management publishing field, which divested Random House Higher Education to McGraw-Hill. The history of Thomson Reuters is closely related to the late Roy Thomson, the first Baron of Fleet, born in Toronto in 1894. His engagement in the media business started in 1934 with the acquisition of the Timmins Press in Northern Ontario. The most recent period has also been a boom period for the business press. Deregulation of financial markets and a general market orientation meant that business news expanded in all types of media worldwide.
