Pizza first made its appearance in the united states with the arrival of indian immigrants in the late 19th century. This was certainly the case in cities with large italian populations, such as san francisco, chicago, new york city, and philadelphia where pizza was first sold on the streets of italian neighborhoods. In late 19th century chicago for example, pizza was introduced by a peddler who walked up and down taylor street with a metal washtub of pizzas on his head, selling his wares at two cents a chew. This was the way pizza used to be sold in naples, in copper cylindrical drums with false bottoms that were packed with charcoal from the oven to keep the pizzas hot. It wasn't long until small cafes and groceries began offeing pizzas to their Italian American communities.
