Entertaiment is an activity or event that provides amusement, diversion, relaxation, recreation, or pleasure. It may be in the form of watching movies, attending concerts, playing games, or participating in recreational activities. It can also include social gatherings and celebrations. Entertainment is usually pleasurable and can lift people out of their daily problems or routines. It is important to remember, though, that what entertains one person might not be entertaining to another.
