How many segments are there in a Terry's Chocolate Orange?

A Terry's Chocolate Orange is an orange-shaped ball of milk chocolate combined with orange extract and divided into 20 segments, similar to a real orange. It is packaged in orange-coloured foil. It was first produced at Terry's Chocolate Works in York, England, in 1932.

There have been number of spin-off versions of the Chocolate Orange, notably the Chocolate Orange Bar, made up of six small segments. A bag of small segments is also available, marketed as Chocolate Orange Minis.

Terry's initially created the Dessert Chocolate Apple in 1926, which was gradually phased out after the Second World War. In 1979, Terry's launched the Chocolate Lemon, but it was withdrawn three years later.

The Chocolate Orange is known for its unusual adverts, which are usually shown on British television at Christmas. One of its well-known marketing slogans is "It's not Terry's, it's mine", although more recent adverts feature the words "Deliciously Unsquare".
