The fridgeAnother invention that became popular in the 1920s was the home refrigerator. People used different ways to keep food cool and fresh long before the 1900s, but home fridges weren’t invented until 1913 in the USA. Home fridges became very popular in the USA in the 1920s. Sales of the popular ‘Frigidaire’ model increased from 5,000 in 1921 to 750,000 in 1926. British people were less interested in fridges than Americans. They thought that they were unnecessary because the weather in Britain was cooler. But fridges were heavily advertised, and their advantages were described in detail. Soon, more fridges were sold, and the price decreased. Home refrigerators were invented in the 1920s.
