In the 1930s, camps took on a larger scale with the establishment of large chains. The first of these was Warners, founded by Harry Warner who opened his first site on Hayling Island in 1931, with another three opening before the outbreak of World War II. During the early 1930s, Warner asked funfair entrepreneur Billy Butlin to join the board of his company and in 1935 Butlin observed the construction of Warner's holiday camp in Seaton, Devon. Butlin learned from the experience of Warner, and employed the workers who had constructed the Seaton camp to build his first camp under the Butlins name at Skegness, Lincolnshire in 1936. By the outbreak of World War II, Butlin had two camps and a third under construction. By 1939, there were around 200 holiday camps in the United Kingdom, at different seaside locations.
