"Advertising" or "advertisement" comes from Latin “advertere”, which means an approach to arouse public attention to something and induce a certain direction. Traditional definitions of advertising include a series of elements that distinguish the field from others. Each innovation in communication has been used for advertising, and in some way, each has changed advertising, which in turn has changed the set of elements used in its definition. However, there are or should be some essential elements that determine whether an activity is advertising, that is to say, the essential meaning is largely identical but with minor differences. In short, advertising is the non-personal communication of information usually paid for and usually persuasive in nature about products, services or ideas by identified sponsors through the various media. And we can learn the functions of advertising from the definition above which are listed as follows:1)information function; 2)demand creation function; 3)persuasive function; 4)get attention function; 5)goodwill establishment function.
