The World Today, Chatham House's monthly magazine, was founded in 1945. Throughout this period it has offered the best and brightest insights and analysis on current affairs – from the fallout of the Second World War, through the Cold War, into the information age and the "war" on terror. The articles are written by experts and scholars and the magazine is distributed worldwide and read by politicians, students, academics, business planners and others simply interested in keeping up-to-date on world affairs through authoritative sources. The magazine goes to subscribers in more than eighty countries. Many hundreds of libraries find it essential. Chatham House's 4,500 individual and corporate members also receive the magazine; a recent survey conducted by our membership department found 79 percent of those read it regularly.

The Royal Institute of International Affairs, also known as Chatham House, is one of the world's leading institutes for the analysis of international issues. Founded in 1920, the Institute works to stimulate debate and research on political, business, security and other key issues in the international arena. It does this through its research, meetings, conferences and publications as well as through its library and information centre and expert interviews for the media. The Chatham House Rule, used worldwide to allow for free speech and confidentiality at meetings, originated here. The Institute has a presence in the USA, where the Chatham House Foundation exists to promote support for Anglo-American relations, and to make the Institute more accessible to an American audience.
