John Grierson is considered the pioneer of the documentary genre. In the 1920s and 1930s in Britain, he believed documentaries could both inform and unite audiences during difficult economic times. His first film, Drifters (1929), showed fishermen working together to promote British togetherness. During World War 2, documentaries took on propaganda roles, with Grierson producing films to counter Nazi propaganda. In the 1950s, the direct cinema movement sought to capture real, unstaged footage of real people and events. Modern documentaries have become more narrative-driven and theatrical to attract larger audiences, though lower budgets remain an issue and funding from broadcasters can influence productions.
