Well, the question here is complicated. The simplest way to answer this question is to ask “What are the differences between the 1950’s and 1920’s?” In other words, what’s the difference in entertainment? Did people in the 1920s have radio or TV? How did having TV impact the 1950s and change Americans? The 1920s are immediately post World War 1. What were the impacts of world war 1 on America? In comparison the 1950s are immediately post ww2. How did world war 2 impact American life?
