Which do you think had the most profound impact on American society in the 1920s, the radio or the automobile? Explain your answer.

ANSWER
Both technologies were alleged to promote family “togetherness” and have a nationalizing influence. Radio promoted racial and ethnic stereotypes, boosted mass consumption, and helped create folk heroes like Charles Lindbergh. The automobile promoted adolescent rebellion and created new sexual opportunities. It was also critical to the economic health of many collateral industries like steel and petroleum.
