There is one place in the US that has a tea culture, and it's an iced tea culture. Lipton would most likely sell tea that meets that demand and let's the rest of the tea drinkers cope than, even if it does make a cup of something not entirely unlike tea for people who were raised on the stuff.
Its a historical artifact. The US is the one country iced tea is consumed more than hot tea. This dates back to the revolution and the resentment of tea taxes that lead to coffee being the "patriot's drink". Iced tea became popular in the 1900's.
