One important development in the 20th century was the introduction of soft ice cream (like Mr Whippy uses!).

Before become a member of parliament,  former British Prime Minister Margaret Thatcher whilst working as a research chemist for J.Lyons & Co and developing emulsifiers, quite literally found a way OF TAKING ICE CREAM FROM CHILDREN.
