Entertaiment is the activity of keeping someone amused, engaged, or distracted. The clown at a kid’s party, Broadway musicals, stadium rock concerts, your friends fighting over the last potato chip—these are all forms of entertainment. The word derives from the Latin intertenere, meaning “to hold inside.” We now use it to mean the act of entertaining, or the entertainment itself. Entertaiment is a multi-faceted, audience-centered commercial culture that spans multiple media. Some collocations, such as a clown or a musical, are familiar from one medium to another, but some, like the term sex entertainment, have a more limited scope and reach.
