The Empire Marketing Board was formed in May 1926 by the Colonial Secretary Leo Amery to promote inter-Empire trade and to persuade consumers to ‘Buy Empire’.
The EMB had three principal aims: to support scientific research, promotion of economic analysis, and publicity for Empire trade. Scientific research took up a large proportion of the EMB’s work and budget. It also had its own EMB film unit led by John Grierson, often considered the father of modern documentary film, which produced around 100 films with such names as ‘Solid Sunshine’ (which promoted New Zealand butter), ‘Song of Ceylon’, ‘Wheatfields of the Empire’, ‘Industrial Britain’ and ‘One Family’.
Colonial governments were reluctant to join the EMB, however. The EMB was ended September 1933 as a result of government cuts and the introduction of Imperial Preference.
