Guardian Media Group exists to support the core purpose of its owner, the Scott Trust: to secure the financial and editorial independence of the Guardian in perpetuity.
In March 2007 GMG sold 49.9% of Trader Media Group to Apax Partners, in a deal that valued Trader Media Group at £1.35 billion. In December 2007 it was announced that GMG and Apax had made a successful bid to buy Emap's business-to-business arm for around £1 billion. Their main competitor is the Daily Mail and General Trust who have operations all over eastern Europe as well as the UK.
