The English name of Snickers is Snickers. Trademark: The Snickers logo design consists of the English letters "SNICKERS" alone, with red, white and blue colors, with dark blue capital letters as the main feature, and a red frame with white hollows as a supplement.

Development history: Starting in 1930, the Mars family began to produce their second product, Snickers, named after their beloved horses.

In the UK and Ireland, the original name of Snickers was Marathon, and it was not until 1990 that it was changed to the international trade name of Snickers. For 18 months before the name change began, the words "Internationally known as Snickers" were printed on product packaging. After the name change, Snickers (formerly Marathon) rose from ninth to third place in the UK chocolate bar sales rankings.

However, the negative impact of the renamed Snickers is that the product name is very close to the British English word knickers for describing "underwear", which can easily lead to people's association. Mars applied for the original trademark to be a British registered trademark in the UK. After the name change, some people launched a campaign to return Marathon because they loved the old name or for other reasons.

In 2004, the "Manifesto for Food and Health" campaign was launched by the British Food and Drink Federation (Food and Drink Federation). During this period, the extra large Snickers chocolate Rods were replaced with other specifications. The British Food and Drink Federation's Food and Health Manifesto campaign includes a set of seven initiatives launched to the food industry. These initiatives include: reducing unit size, clearer labelling, reducing fat, sugar and salt.

After these initiatives were launched, Mars withdrew its extra-large Snickers in 2005 and replaced them with exclusive packages. A Mars spokesperson said: "Our king-size bars will be replaced by two smaller, premium sizes that consumers can share with friends or enjoy in portions. King-size ) will no longer be available."

As a result, the Snickers Duo, consisting of two small bags, replaced the original extra large bag. Although the weight of the new product has been reduced from 3.5 ounces (99 grams) to 3.29 ounces (93 grams), the selling price has not changed. Selling a large chocolate bar in two packages allows consumers to share it with others or make it easier to eat in portions. There are even four-panel illustrations on the outer packaging of Snickers Duo that teach you how to divide it into two parts.
