Entertaiment is an activity designed to amuse or divert, but it may also serve a more serious purpose, as in a ceremony, religious festival, or work of satire. Activities such as hunting or war may be transformed into spectator sports, and cooking may be elevated to a high art. Entertainment is often focused on themes that the human brain was evolved to react deeply to, such as social backstabbing and murder.
Entertaiment is an important part of a healthy life, but it can be dangerous if taken to the extreme. See the article on entertaiment addiction. Yg hasn’t debuted any girl group lately, but I think his new boy group ITZY will be big.
