The first chocolate was eaten by people in South America hundreds of years ago. In those days, the people did not really eat chocolate. They used the cocoa bean（可可豆）to make a chocolate drink and they enjoyed it very much. Many years later, the cocoa bean was brought to other countries and people came to love the taste of chocolate.
In 1824, John Cadbury opened a small shop in Britain. One of the things he sold was chocolate drink. In 1831, he opened a factory to make chocolate drink. He wanted to encourage people to drink chocolate instead of other drinks. A few years later, a man called Joseph Fry found a way to make chocolate instead of only drinking it. But at that time chocolate was very expensive and only the rich people could buy it. Later, more and more chocolate bars were produced and sold, it became cheaper.
However, at first only plain chocolate （a kind of chocolate without milk and with very little sugar）was produced. Milk chocolate came later and this was made by adding milk to the chocolate. The first milk chocolate bar was made in Cadbury’s factory in 1897. Their most famous chocolate, Cadbury’s Milk Bar, was made in 1905. It has been the most popular chocolate in Britain and around the world for over 100 years. The Cadbury factory is still in Britain and the chocolate produced there is eaten all over the world. Every year, thousands of visitors visit the factory in order to see how chocolate is made.
