It has offices in 43 countries and around 11,000 employees. Informa owns numerous brands including CRC Press, Fan Expo, Institute for International Research, Lloyd's List (London Press Lloyd), Penton, Routledge, Taylor & Francis, and UBM.
The company has recently acquired UBM and Penton as part of its strategy to expand in North America and Asia.
Informa's oldest business started in 1734 when Lloyd's List, now one of the world's oldest continuously running journals, began covering London shipping news.
Informa itself was created in 1998 by the merger of IBC Group plc and LLP Group plc. Since then Informa has expanded considerably, including a 2004 merger with the publishing company Taylor & Francis and a 2005 acquisition of IIR Holdings, a human capital development company, for £768 million.
In 2013, Informa acquired the Canadian company Hobby Star Marketing, which runs the comic book convention brand Fan Expo. Informa has since acquired other conventions and placed them under Fan Expo's auspices, including Dallas Comic-Con and MegaCon.
