Sliced bread
Sliced bread was sold for the first time in 1928 at the Chillicothe Baking Company in Chillicothe, Missouri. Before then, people sliced their own bread. Bread consumption increased, because people found it easier to grab a slice and go. Consumption of butter, jam, and other spreads increased as well. For a short time during World War II sliced bread could not be sold. The invention led to the saying, “the best thing since sliced bread.”
