Tanya Barson looks at the rich history of art and documentary in Britain from 1929 to now.
The 1930s and 1940s can be viewed as the era in which documentary was first defined and given recognition as an independent area of production. Central to this was the film movement of the 1930s, led by the producer and film-maker John Grierson, who had coined the term 'documentary'.
Grierson defined documentary as 'the creative use of actuality'. He was influenced by modernist film practice, yet attempted to reintroduce social commentary into avant garde film.
