What is the definition of Display Copy used in Advertising?

Text of a print, radio, or television message that aims at catching and holding the interest of the prospective buyer, and at persuading him or her to make a purchase—all within a few short seconds. The headline of an advertising copy is said to be the most important part, and quite often a small change in its Wording brings disproportionate results. Although a short advertising copy is more common in consumer-product advertising, according to the UK advertising guru David Ogilvy people do read (and listen or attend to) lengthy advertisements if they are skillfully written. Most advertising copy is based on advertising/consumer research and is composed by professional copywriters hired by advertising agencies. Also called advertisement copy, ad copy, or just copy.
