Purpose-built cinemas began appearing around Britain shortly before WWI, booming in popularity during the War and developing into the ‘picture palaces’ of the 1920s - when adverts jostled for space alongside newsreels before the main feature. Local businesses were quick to see the potential of a big screen and a captive audience to promote their wares.
While they didn’t have access to the budgets of the national brands, regionally-specific businesses had the benefit of that personal touch. Products and services evolved over time, but that scratchy ad for your local Indian restaurant, so integral to the cinema-going experience into the 1990s, had its roots in the booming entrepreneurship of the industry many decades before.
