Mars, commonly known as Mars bar, is the name of two varieties of chocolate bar produced by Mars, Incorporated. It was first manufactured in 1932 in Slough, England by Forrest Mars, Sr.^[2] The bar consists of caramel and nougat coated with milk chocolate.

An American version of the Mars bar was produced which had nougat and toasted almonds covered in milk chocolate; later, caramel was added to the recipe as well. The American version was discontinued in 2002, then revived in a slightly different form the following year under the name "Snickers Almond".

In most of the world, a Mars bar is a chocolate bar with nougat and caramel, coated with milk chocolate. In the United States, it is marketed as the Milky Way bar.^[3]

It was first manufactured in Slough, England under the Mars bar name in 1932 by Forrest Mars, Sr., son of American candy maker Frank C. Mars.^[2] He modelled it after his father's Milky Way bar, which was already popular in the US, adjusting the recipe to better suit European tastes.^[4][5] He had a staff of twelve people, and originally advertised it as using Cadbury's chocolate couverture.^[5][6] The bar and the proportions of the main components have changed over the years. With minor variations, this version is sold worldwide, except for the US, and is packaged in a black wrapper with red gold-edged lettering. Three million Mars bars accompanied the British task force to the Falklands in 1982.^[7]

The Mars brand logo went through several changes. In 1932, the first logo had a black colour font and was tilted. In 1978, the logo was rebranded to being white and having a star on the side. In 1988, the Mars bar had went through a significant change with its logo. At that time, the logo was given a more bombastic treatment, written with red thick font and golden outlier. This logo became the standard-form for future logos. The logo then changed again, in the early 2000s. This time the logo was given a much more modern and sleeker look. It was updated to have a more cursive appearance to it and has retained that appearance ever since. ^[8]

The nougat was made lighter, the chocolate on top became thinner, and the overall weight of the bar was reduced slightly. The slogan "Pleasure you can't measure" was intended to appeal more to women and youths.^[9]

Various sizes are made. As of 2008: miniature bars called "Fun Size" (19.7 g, 0.69 oz) and "Snack Time" (36.5 g, 1.29 oz) (both sold in multiple packs); a larger multi-pack size of 54 g (1.9 oz); the regular-sized single 51 g (1.8 oz) bar, and a "king-size" 84 g (3.0 oz) bar, since replaced by "Mars Duo" (85 g or 3.0 oz), a pack of two bars. The regular 58 g (2.0 oz) single bar contains 260 calories.^{[citation needed]}

In the second half of 2008, Mars UK reduced the weight of regular bars from 62.5 g (2.20 oz) to 58 g (2.0 oz). Although the reduction in size was not publicised at the time, Mars claimed the change was designed to help tackle the obesity crisis in the UK, but later acknowledged that the real reason for the change was rising costs.^[10] In 2013, the "standard" Mars bar was further reduced to 51 g (1.8 oz), for a reduction of about 20% in 5 years;^[11] it continued to be 51 g (1.8 oz) in 2023.^[12]

In May 2009, the Mars bar size reduced from 60 g (2.1 oz) to 53 g (1.9 oz) in Australia, citing portion sizes and the obesity debate as the primary driver.^[13][14] By 2022 it was noted the Mars bar size had been reduced further to 47 g (1.7 oz) in Australia and New Zealand.

In the United States, the Mars bar was a candy bar with nougat and toasted almonds coated with milk chocolate. The same candy bar is known outside the United States as a Mars Almond bar. Originally^[when?] it did not have caramel, but at some point caramel was added.^{[according to whom?]} It was discontinued in 2002.^[15]

In 2003, the company introduced a replacement called Snickers Almond containing nougat, almonds, caramel, and a milk chocolate coating,^[15] It is similar to the Mars bar, with some differences; for example, the pieces of almond are smaller in Snickers Almond than in the Mars bar.

The Mars bar was relaunched in January 2010 (initially exclusively through Walmart stores), discontinued again at the end of 2011,^{[citation needed]} and relaunched again in September 2016 by Ethel M, the gourmet chocolate subsidiary of Mars, Inc. The 2016 version was the "original American recipe", without caramel. It was available in their stores and on Amazon.com.^[16][17]

The European or Canadian version of the Mars bar is sold in some American grocery stores that stock imported food products.

Other products have also been released using the Mars name.

The Original Mars bar in "Believe" packaging was sold in the UK from 18 April 2006 until the end of the 2006 FIFA World Cup in July. "Believe" took prominence on the packaging ("Original Mars" appeared in smaller print) to indicate support for the England national football team. Advertising in other nations of the UK was tailored to reflect their own teams after public condemnation, although in Scotland the "Believe" packaging was still used – causing negative publicity.^[21]

On 30 July 2008, the Tasmanian government announced that it had secured a major sponsor, Mars for a bid to enter the Australian Football League in a deal worth $4 million over 3 years and will temporarily change the name of its top-selling chocolate bar in Australia to Believe, to help promote Tasmania's cause.^[22]

Mars were re-branded "Hopp" ("Go!" in English) in Switzerland during UEFA Euro 2008. Like the "Believe" packaging sold in the UK in 2006, "Original Mars" was also shown in smaller print.^[23]

In 2010, to promote England's involvement in the 2010 FIFA World Cup, the background of the UK Mars packaging became the St. George cross.

First reports of Mars bars coated with batter and deep-fried being sold in Stonehaven, Scotland^[26][27] date back to 1995.^[28] Mars says that it is "not authorised or endorsed".^[29]

Deep-fried Mars bars were also sold in New York.^[30]

In Kathmandu, Nepal, momo dumplings in tourist areas have used Mars bars as an unusual filling.^[31]

In July 2005, Mars bars, along with the Snickers bar, were recalled due to an anonymous extortion attempt against Star City Casino in Sydney.^[32] The extortionist claimed to have poisoned seven Mars and Snickers bars at random stores in New South Wales.^[33] As a result, Masterfoods Corporation, the company that manufactures Mars bars in Australia, recalled the entire Mars and Snickers product from store shelves in New South Wales.^[32] In the later half of August 2005, the threat to the public was deemed negligible and the bars returned to shelves.^[34]

In February 2016, Mars, Snickers and various other Mars, Inc. chocolate products were recalled in 55 countries in Europe, the Middle East and Asia. The precautionary recall was issued after a customer found pieces of plastic in a Snickers bar purchased in Germany. The error was traced back to a Mars, Inc. factory in Veghel, The Netherlands.^[35][36][37]

In May 2007, Mars UK announced that Mars bars, along with many of their other products such as Snickers, Maltesers, Minstrels and Twix would no longer be suitable for vegetarians because of the introduction of rennet, a chemical sourced from calves' stomachs used in the production of whey.^[38] Rabbinical authorities declared that the products remained kosher for Jewish consumption.^[39]

The decision was condemned by several groups, with the Vegetarian Society stating that "at a time when more and more consumers are concerned about the provenance of their food, Mars' decision to use non-vegetarian whey is a backward step".

Mars later abandoned these plans, stating that it became "very clear, very quickly" that it had made a mistake.^[40]

It has been observed on several occasions that the price of a Mars bar correlates fairly accurately with the change in value of the pound sterling since World War II, much in the way that the Big Mac Index has proven to be a good indicator of the actual relative purchasing power of world currencies.^[41]

Northern Irish pop-punk band The Undertones wrote and recorded a song called "Mars Bars", released as a B-side in 1979.^[42]

1960s Liverpool band Gerry and the Pacemakers were originally known as Gerry Marsden and the Mars Bars before changing their name due to the objection of the Mars company.^[43]

The 1990 Newbery Medal winning novel Maniac Magee includes a character nicknamed "Mars Bar" Thompson for his habit of eating Mars Bars.^{[citation needed]}
