The "radio" became very powerful in the <em>1920s.</em> Every American home displayed the radio as a necessity for entertainment.<u> It immediately became a means for many advertisers to reach out to their consumers</u>. 
<em>This gave them a chance to reach a broader variety of people. </em>Since this era was a prosperous time for people, the consumer goods increased. Many manufacturers used the radio as a means to advertise their goods and it was indeed an effective method. 
Consumption culture grew, <u>whereby people purchased goods by credit. </u>For example, the radio would announce to people that if they cannot afford to purchase a specific good for its price, then they can do so by paying it in installment basis.
