The History of Ice Cream

I recently learned some interesting facts about the history of ice cream. Here they are:

• Immigrants to Ellis Island were given free ice cream as part of their menu in 1920.
• The prohibition was a boon to the ice cream industry because almost of the breweries began to produce ice cream. Indeed, demand for ice cream from 1920 to 1930 soared 71%.
• One year after its introduction, in 1922, one million Eskimo Sandwiches were sold in America. Demand was so high just for the chocolate that covered the ice cream in these sandwiches that the resulting cocoa sales lifted Ecuador out of its depression. 
• The mafia demanded to control some of the Good Humor Ice Cream routes. When Good Humor failed to relent, the mafia blew up some eight Good Humor Ice Cream trucks. Despite the tragedy, the resulting publicity boosted ice cream sales.
• Due to its seratonin producing ability, eating ice cream lowers blood pressure.
• "Overrun" is the percentage of air that is added to ice cream. Some air must always be added to ice cream, otherwise ice cream would essentially be all ice and thus inedible. The more air that is added to ice cream, the cheaper the ice cream becomes.
