Milk chocolate is a form of solid chocolate containing cocoa, sugar and milk. It is the most consumed type of chocolate, and is used in a wide diversity of bars and other confectionery products. Milk chocolate contains smaller amounts of cocoa solids than dark chocolates do, and (as with white chocolate) contains milk solids. While its taste (akin to chocolate milk) has been key to its popularity, milk chocolate was historically promoted as a healthy food, particularly for children.

Major milk chocolate producers include Ferrero, Hershey, Mondelez, Mars and Nestlé; collectively these supply over half of the world's chocolate. Four-fifths of all milk chocolate is sold in the United States and Europe, and increasing amounts are consumed in both China and Latin America.

Pet food is animal feed intended for consumption by pets. Typically sold in pet stores and supermarkets, it is usually specific to the type of animal, such as dog food or cat food. Most meat used for animals is a byproduct of the human food industry, and is not regarded as "human grade". Examples of foods for pets would be canned foods and dry mix. Pet food production has environmental, land-use and climate change impacts.

In 2019, the world pet food market was valued at US$87.09 billion and is projected to grow to US$113.2 billion by the year 2024. The pet food market is dominated by five major companies, as of 2020: Mars, Inc., Nestle Purina Petcare, J. M. Smucker, Hill's Pet Nutrition, Inc. (owned by Colgate-Palmolive), and Blue Buffalo Co. Ltd (owned by General Mills).

The World Cocoa Foundation is a non-profit membership organization with more than 90 member companies striving to make the cocoa supply chain more sustainable. WCF and its members are criticized for doing too little to end child labor, deforestation and extreme poverty, with their efforts dismissed as greenwashing and “a remarkable failure”. WCF's membership includes chocolate manufacturers such as Mondelez International, Nestlé, The Hershey Company and Mars, Inc. cocoa producers and suppliers such as Barry Callebaut and Cargill, shipping companies and ports and retailers such as Starbucks.

Cadbury, formerly Cadbury's and Cadbury Schweppes, is a British multinational confectionery company owned by Mondelez International (spun off from Kraft Foods) since 2010. It is the second-largest confectionery brand in the world, after Mars. Cadbury is internationally headquartered in Greater London, and operates in more than 50 countries worldwide. It is known for its Dairy Milk chocolate, the Creme Egg and Roses selection box, and other confectionery products. One of the best-known British brands, in 2013 The Daily Telegraph named Cadbury among Britain's most successful exports.

Cadbury was founded in 1824 in Birmingham, England, by John Cadbury (1801–1889), a Quaker who sold tea, coffee and drinking chocolate. Cadbury developed the business with his brother Benjamin, followed by his sons Richard and George. George developed the Bournville estate, a model village designed to give the company's workers improved living conditions. Dairy Milk chocolate, introduced by George Jr in 1905, used a higher proportion of milk in the recipe than rival products. By 1914, it was the company's best-selling product. Successive members of the Cadbury family have made innovations with chocolate products. Cadbury, Rowntree's and Fry's were the big three British confectionery manufacturers throughout much of the 19th and 20th centuries.
