I believe you are talking about the Columbian Exchange. This was the importing, exporting, and trading of goods between the Old World and New World. Some products included coffee, chocolate, silver, cotton, and various spices.
The Columbian Exchange is the term given to the transfer of plants, animals, disease, and technology between the Old World from which Columbus came and the New World which he found. Some exchanges were purposeful — the explorers intentionally brought animals and food — but others were accidental.
