Mars is a chocolate bar produced by the company Mars, Incorporated.
The first Mars bars were produced 1932 in Berkshire in the United Kingdom. They were advertised as having Cadbury chococolate as couverture.
There was a separate chocolate bar in the US also called Mars. It came with nougat, soft caramel, almonds, and milk chocolate. It was discontinued in 2002, but a similar bar with the name Mars was reintroduced in the US in 2010.
Today, many different spin-offs of the Mars bar are being sold, including deep-fried Mars bars, drinks, ice cream bars, and many others.
