How did the first sliced bread and other famous foods get their names? It has been a mystery for a long time. Some researchers have decided to compile the answers and finally there is a surprising story behind the brand name. (26)Consumers had long been slicing bread themselves and any store-bought bread before the late 1920s was unsliced, and people could just bite on the loaf. But even Wonder Bread wasn’t sliced at first. Created in 1921 by the Taggart Baking Company of Indianapolis, Indiana, the new bread was almost ready for market when the question of a name arose. Making a striking name for his new bread was really a tough question. Vice president Elmer Cline happened to attend a balloon race one day. (27)The sight of dozens of brightly colored hot-air balloons in the sky filled him with, as he later said, "Wonder." And afterwards, Wonder Bread was born. (28) Cline, in fact, was so impressed with the sight of those balloons that he covered his new product’s wrapper with red, yellow and blue balloons, which is still Wonder’s package design today. You might think that a product combining balloons, bread and a sense of wonder wouldn’t get any better. But in 1933, Wonder introduced the very first pre-sliced loaf of bread to American consumers, the popularity of which is reflected in that phrase—"the best thing since sliced bread."
