Television had a huge impact on American culture. Many call the 1950s "The Golden Age of Television." At the time, televisions were very expensive, so they were mainly reserved for the rich. Because the rich enjoyed the theater, directors starting filming Broadway shows in film studios. Ultimately this led to less attendance in the theater.
Also, the television shaped ideas about family life and accepted behavior. It normalized being white since almost all of the people on the television were white. It also portrayed how men and women should act and what their roles in the family should be. This also included things like appropriate social class and religion.
