Why are freezers on top of a refrigerator?

The coldest part of the ice box used to be the top part, where the ice was inserted. When Ice was no longer used, the cooling system fed into the top and the cold would go down.

However, you can buy refrigerators with the freezer on the side or the bottom. We like the bottom type, because it puts the fridge higher and we are fairly tall.
