[3] It is manufactured and distributed by the Hershey Company in the United States under licence from Cadbury, with a recipe that differs from the UK version.

[4] The chocolate is now available in many countries, including China, India, Sri Lanka, Pakistan, the Philippines, Indonesia, Kazakhstan and Bangladesh.

[2][5] Accounts on the origin of the Dairy Milk name differ; it has been suggested that the name change came about on the advice of a shopkeeper in Plymouth, but Cadbury maintains that a customer's daughter came up with the name.

The chief nutritionist of Public Health England, Alison Tedstone, said she was "pleased that Mondelez is the latest … name" to offer "healthier" products.

[16] As part of the celebrations, seven retro limited edition packaging designs of Cadbury Dairy Milk bars were relaunched from 1915, 1940, 1961, 1980, 1993, 2003 and 2024.

[22] According to a 2007 report in The New York Times, a British bar contained (in order) milk, sugar, cocoa mass, cocoa butter, vegetable fat and emulsifiers, whilst the American version manufactured by Hershey started its list of ingredients with sugar.

[4] According to its spokesman, Cadbury tries to adapt the taste of the product to that which local consumers are accustomed, meaning it is more akin to a Hershey bar for the US market.

[27] The advert has over twenty million views on YouTube, and put the Phil Collins song back into the UK charts.

The ad, entitled 'Trucks' features several trucks at night on an empty runway at an airport racing to the tune of Queen's "Don't Stop Me Now".

[29] On 5 September 2008, the Gorilla advert was relaunched with a new soundtrack – Bonnie Tyler's "Total Eclipse of the Heart" – a reference to online mash-ups of the commercial.

[30] In January 2009, 'Eyebrows', the third advert in the series, was released, of two children moving their eyebrows up and down rapidly to the song "Don't Stop the Rock" by Freestyle.

Chocolate fountains were put in shopping centres such as Westfield London and the first ad focused on the relaunch of Dairy Milk Bubbly.

In addition, Cadbury also brought the Joyville concept into Asia, where Singapore bloggers were invited to join in the campaign in 2013.

[33] A new design was launched for Dairy Milk (and its variants) inviting consumers to scan an on-pack QR code and visit a website featuring "Free The Joy" moments.

[41] British Dairy Milk has been blind taste-tested as providing a creamier taste and texture, with the Hershey's-made chocolate reportedly leaving a less pleasing coating on the tongue and a somewhat stale aftertaste.

[41] Cadbury was fined £1 million in July 2007 due to its products having been found to have been at risk of infection with salmonella (at a factory in Marlbrook, Herefordshire, England).

[42] On 14 September 2007, Cadbury Schweppes investigated a manufacturing error over allergy warnings, recalling for the second time in two years thousands of chocolate bars.

A printing mistake at the Keynsham factory resulted in the omission of nut allergy labels from 250g Dairy Milk Double Chocolate bars.
