<span>The character and quality of life changed dramatically in Nebraska during the 1920s….The effects of technological change were most obvious in the cities. By the 1920s most small cities had paved streets, municipal electricity and water systems, telephone systems, streetlights, and sewage systems… The homes of most urban Nebraskans had running water and indoor plumbing…Electricity appeared in homes on a grand scale during the 1920s, at first for illumination but by the end of the decade for washing or sewing machines, irons, toasters, mixers, and vacuum cleaners…Refrigerators began to replace iceboxes for short-term food preservation, and electric fans began to cool hot summer days.
