Advertising is a way of informing people of something.This can range from telling them of a product for sale,or a service,or urging them to do something,or even to bring one’s name before the public.So advertising came out quite naturally and took many forms from the very beginning.For example,there is a papyrus discovered at Thebes offering a reward for a runaway slave.It is three thousand years old—and it’s really an advertisement!Signboards that notified people of services available were placed outside doors in Greece and Egypt around 1500 B.C.—a form of advertising.With the invention of printing,advertising began to take on new forms.About 1477,in London,the first printed advertisement in English announced a prayerbook sale.
