Cadbury Dairy Milk is a brand of milk chocolate introduced in the UK in 1905. It became Cadbury's best selling product by 1914 due to its higher milk content compared to other chocolates. Over time, additional Dairy Milk products were introduced like Fruit and Nut in 1928. While originally produced in the UK, many Dairy Milk varieties are now manufactured in other countries like Ireland, France, and Poland. In the US, Dairy Milk is produced under license by The Hershey Company.
