One of the most popular and nowadays among the most used goods, the tomato, came from the New World and was introduced in the Old World.
The tomatoes originated as a wild plant in the Andes, on the territories of modern-day Ecuador, Peru, Bolivia, and Chile. The people living in this region saw their potential and started to cultivate them, and seeing what a delight they are, other people from other parts of the New World started to cultivate them as well.

Over time, this changed as people saw that they have a wonderful food product, so the tomato became one of the most popular goods.
