Sliced bread is a loaf of bread, sliced with a machine and packaged for convenience, as opposed to the consumer cutting it with a knife. It was first sold in 1928, advertised as "the greatest forward step in the baking industry since bread was wrapped". By 1933, around 80% of bread sold in the US was pre-sliced, leading to the popular idiom "greatest thing since sliced bread".
