As theater became more sophisticated, audiences began to show their appreciation in a more reserved manner. They might still applaud, but they would also be more likely to listen quietly and attentively to the play. They might also show their appreciation by talking about the play after it was over, or by writing letters to the actors or playwright.
Today, audiences at plays still express their appreciation in a variety of ways. Some people still applaud and cheer, while others prefer to sit quietly and enjoy the performance. Some people even write letters or emails to the actors or playwright to let them know how much they enjoyed the play.
No matter how they choose to express it, audience appreciation is an essential part of theater. It lets the actors and playwright know that their work is being appreciated, and it helps to create a positive atmosphere for the performance.
