The reasons for the movement toward a mass consumer society in the 1920s were rooted in a variety of factors, including the rise of mechanized production and new advertising techniques. This trend was driven by newly available technologies such as the radio and increased purchasing power due to rising incomes. The consequences of this new consumer society included an increase in material consumption, higher standards of living for some, and an expanded role for the federal government in regulating production and consumption. It also created a new age of corporate growth and helped to cause the Great Depression when demand outpaced supply.
