Guardian Media Group

Guardian Media Group, usually shortened to GMG, is a British mass media company that owns media operations including The Guardian and, until its sale in April 2025, The Observer. The business began in 1907 as the Manchester Guardian Ltd., after C. P. Scott bought The Manchester Guardian, and it took its present name in 1993. The group is wholly owned by the Scott Trust Limited, a body that exists to secure the financial and editorial independence of The Guardian in perpetuity, so the company answers to a trust rather than to outside shareholders. Over the years it has bought and sold large stakes in other media businesses, among them regional newspapers, radio stations, the Trader Media Group and a business-to-business publishing arm. Its leadership has included Carolyn McCall, Andrew Miller, David Pemsel, Annette Thomas and, from August 2022, Anna Bateson as chief executive.
