Entertaiment is a broad category of human activity that includes playing games, watching performances and sports, and participating in other social activities. It can be a form of education or training, as when children engage in play that mimics adult activities and prepares them for future responsibilities; or it can be an exercise in fitness or relaxation. It can also involve a range of other activities, including work, and can be found on many scales – from a single person choosing entertainment from a vast array of pre-recorded products; to a dinner for two; to a performance for thousands or for the global audience.
