There are some old confectionaries out there, but perhaps none predates Cadbury. While it didn't start out producing chocolates when it was founded in 1824 -- John Cadbury sold drinking chocolate, as well as coffee and tea -- the brand has continued for nearly 200 years. Cadbury's big breakthrough came in 1905 when it introduced its famous Dairy Milk. Within a decade it outsold coffee, tea, and drinking chocolate, charting the path for Cadbury into the 20th Century. After a merger with J.S. Fry & Sons in 1919, Cadbury expanded its line products, releasing the world-famous Creme Eggs in 1923 (a different take on Fry's Chocolate Cream). After a merger and then demerger with Schweppes, Cadbury sold to Kraft Foods in 2010 before the company split into two, making it part of Mondelez International. Yet they continue to create some of our favorite candies, including Sour Patch Kids, Swedish Fish, and various gum brands in addition to Creme Eggs and Dairy Milk.
