The story

1998 to 2013

Informa itself was created in 1998 by the merger of IBC Group plc (formerly International Business Communications) and LLP Group plc (publisher of Lloyd's List).

In 2004, Informa merged with academic publisher Taylor & Francis, followed in 2005 with the acquisition of IIR Holdings.

In October 2006, the company was approached by Springer Science and Business Media in a takeover bid, but in early November the Informa board rejected the offer.

In early 2007, chairman Richard Hooper announced his retirement in May and, after consulting with major shareholders, the company moved chief executive Peter Rigby to chairman, and managing director David Gilbertson to Rigby's former post.

On 8 June 2008, The Sunday Telegraph revealed that United Business Media (UBM) had proposed a merger with Informa. The talks were confirmed by Informa in a press release that same day, but described as "preliminary". On 17 June talks with UBM ended.

In May 2009 the company announced that it would restructure its business to be incorporated in Jersey but tax resident in Switzerland. In 2014, Informa was redomiciled in the UK.

In July 2013, the company announced that Peter Rigby would retire at the end of 2013 to be replaced as CEO by Stephen Carter, who was first appointed a non-executive director in 2010. Informa has since acquired other conventions and placed them under the auspices of their Fan Expo HQ brand, including Dallas Comic Con and MegaCon.

In December 2013, Informa acquired the assets of Elsevier Business Intelligence (EBI) from Reed Elsevier.
