When the doughboys returned to the United States after World War I, they discovered there were many well-paying jobs. They found more money available and new products to spend it on. Some new inventions of the time included:
The use of credit cards started in the United States during the 1920's. Individual companies such as hotel chains and oil companies began issuing them to customers for purchases made at those businesses. People could buy "on time". All they had to do was put a little money down and make payments each month. These companies charged interest. This was usually a percent of the purchase to pay for this service. Others began investing in the stock market. They bought shares of the new growing companies of America. Business owners were spending this money to expand their businesses. Chain stores began to grow. In 1920 the A&P Company had 4,000 stores. By 1929 it had almost 16,000.
