Entertaiment is any activity that provides enjoyment and amusement. It is a means of distraction and escape from everyday problems. It can be enjoyed in many forms including theatrical entertainment as shows, visual entertainment such as movies and art, and audio entertainment as music and radio. Bates and Ferri define entertainment as activity that is understood objectively, communicates from text to audience through external stimulus, offers pleasure, requires an audience to exist and occurs in a passive form.
The clown at the birthday party, the Broadway show, your friends fighting over the last potato chip- all are examples of entertaiment.
