When and were was iced tea introduced to the American people?

According to American and British cookbooks ice tea was served in the 1800's and it was often called "punch". The punch was green tea ( not black) and spiked with liquor. They were often regional in the mix and the names so it is hard to tell you where they actually come from. The use of tea as a drink dates back over 5,000 years. With the invention of the refrigerator ice tea became a fact of life and cookbooks show different types including the use of black tea.
