Although solid chocolate for eating was not invented until the early 19th century, milk chocolate appeared in 1876, when it was developed by Daniel Peter, a Swis confectioner. Cadbury's introduced its milk chocolate into the British market in 1905, and by 1913 Cadbury's Dairy Milk was the company's best selling brand. Cadbury's slogan 'a glas and a half of full cream milk in every half pound' began in 1938, and their recipe for chocolate remained basically the same throughout its history.
