Entertaiment — an agreeable occupation of the mind; diversion; amusement: Solving a crossword puzzle is entertainment for many people. The word entertain has also come to be associated with a range of other activities that involve some type of performance: the clown at a birthday party; a Broadway show; a stadium rock concert; your friends fighting over the last potato chip. Entertainments can be as small as an individual choice of a film from a wide array of pre-recorded options; or as large as a festival intended for thousands.
