Entertaiment is an activity that holds the attention and interest of an audience. It can be an idea or a task, but it is more likely to be one of the activities that have developed over thousands of years specifically for the purpose of keeping an audience’s attention. The clown at a birthday party, a Broadway show, a stadium rock concert, and even your friends fighting over the last potato chip are all examples of entertainment. The word comes from the Old French entretenir meaning hold together or support, and it was associated with hospitality as a way to keep guests happy.
