The word entertaiment is often associated with amusement, but many entertainments have a more serious purpose, such as ceremonial occasions, religious festivals, or social satire. Across the centuries, many forms of entertainment have adapted to suit new technology and fashion, but the essence remains the same. Many activities that were once used for hunting or war have become spectator sports; others have shifted from individual entertainment to the sharing of an experience among groups and communities, and then broadcast for a global audience.
