By what year had sales of pre-sliced loaves surpassed those of unsliced bread, fundamentally changing American eating habits?

Answer

1933

The convenience offered by pre-sliced bread, popularized heavily by mass-marketed brands like Wonder Bread introduced in 1930, led to a rapid consumer adoption rate that redefined daily eating habits. Within just three years of mass availability, specifically by the year 1933, the sales figures for loaves already cut into uniform slices overtook the sales of their unsliced counterparts. This shift demonstrates how quickly Americans embraced efficiency in the kitchen, turning what started as a novelty invention into an ingrained expectation for modern domestic living well before the wartime interruptions of the 1940s.
