How did the issues with communism change the entertainment industry?

In the late 40s the Hollywood industry suffered the infiltration of the Red (Communists) that wanted to disseminate the communist ideals by the world of entertainment in Hollywood. That started a hunt for any writer, director or author who gave signs of being a communist, and even thought there were some actual Reds in the world of Hollywood, most of the industry suffered from repression and prosecution without a real reason. That created a very tense atmosphere within the actors, writers and directors who were afraid to express themselves for they could end up banned from the industry. All this generated a severe lack of production and expression.
