Entertaiment is a form of recreation that entertains, amuses, or diverts people from their everyday activities. It can be light-hearted and fun for everyone, or it may involve serious training such as military drills, equestrian competitions, or religious festivals. It can also be a means of social or psychological growth, like play, ritual, or satire. Entertainment evolves and adapts to the needs of an individual or a community, from a private viewing of a recorded product to performances for thousands.
