Cadbury's Hazel Nut Can

In 1905, Cadbury launched its Dairy Milk bar, with a higher proportion of milk than previous chocolate bars, and it became the company's best selling product by 1913. Fruit and Nut was introduced as part of the Dairy Milk line in 1928, soon followed by Whole Nut in 1933. By this point, Cadbury was the brand leader in the United Kingdom. These were accompanied by several other products: Flake (1920), Cream-filled eggs (1923), Crunchie (1929) and Roses (1938).[9] Cadbury's Milk Tray was first produced in 1915 and continued in production throughout the remainder of the First World War. More than 2,000 of Cadbury's male employees joined the Armed Forces and to support the war effort, Cadbury provided clothing, books and chocolate to soldiers. After the war, the Bournville factory was redeveloped and mass production began in earnest. In 1918, Cadbury opened their first overseas factory in Hobart, Tasmania and in 1919 undertook a merger with J. S. Fry & Sons, another chocolate manufacturer, resulting in the integration of well-known brands such as Fry's Chocolate Cream and Fry's Turkish Delight. During World War II, parts of the Bournville factory were turned over to war work, producing milling machines and seats for fighter aircraft. Workers ploughed football fields to plant crops. As chocolate was regarded as an essential food, it was placed under government supervision for the entire war. The wartime rationing of chocolate ended in 1949, and normal production resumed. Cadbury subsequently built new factories and had an increasing demand for their products.
