Entertaiment is the activity of amusing or entertaining oneself for enjoyment and relaxation. It encompasses many forms, such as movies and television shows; listening to music and attending concerts; reading books and poetry; participating in sports or playing video games; or enjoying visual art. Entertainment evolves and can be adapted to fit any scale: from an individual selecting their own private entertainment from a vast array of pre-recorded options; to banquets and parties for couples, friends, or large groups; to performances intended for thousands, or even global audiences. Entertaiment often focuses on themes the human brain was shaped to react deeply to, such as backstabbing and murder.
