Reuters was founded in 1851 by Paul Julius Reuter, a German-born entrepreneur who established a news agency in London. Reuter initially used carrier pigeons to transmit stock prices between Brussels and Aachen, bridging a gap in the telegraph network. He then established a telegraph-based news service in London, providing financial news to banks and brokers.
Reuters expanded rapidly through the second half of the 19th century, establishing bureaus across Europe, Asia, and the Americas. The agency became one of the world's most important sources of international news, providing coverage to newspapers and financial institutions globally.
Throughout the 20th century, Reuters expanded its financial data services alongside its news operations. The company became a major provider of real-time market data, trading platforms, and financial analytics, serving banks, investment firms, and other financial institutions.
Reuters went public on the London Stock Exchange in 1984, raising capital to fund its technology investments. The company continued to expand its financial data business through the 1990s and 2000s, competing with Bloomberg and other financial data providers.
The Thomson Corporation, a Canadian media and information company controlled by the Thomson family, announced a merger with Reuters Group PLC in May 2007. The deal was completed in April 2008, creating Thomson Reuters Corporation. The Thomson family's Woodbridge Company retained approximately 70% of the combined company.
Following the merger, Thomson Reuters reorganized its operations around its core professional information businesses: legal (Westlaw, Practical Law), tax and accounting (Checkpoint), corporates (Practical Law, Contract Express), and Reuters News. The company sold its financial and risk business to a private equity consortium in 2018, which was rebranded as Refinitiv. Refinitiv was subsequently acquired by the London Stock Exchange Group (LSEG) in 2021.
For full-year 2024, Thomson Reuters reported revenue of approximately $7 billion, with growth driven by its legal, tax and accounting, and corporates segments.
