"Advertising is happiness." John Draper, from television show, Mad Men!
Advertising and marketing are often mixed up. Most people think they are the same thing. They generally have the same effect. Well I am sorry their wrong. Advertising has been around, before marketing, but this doesn’t mean it has less importance. They are both important in the line of work you desire. Some consider advertising as one of the components of marketing. Marketing is the research you must do once you develop a product. Marketer care about the consumers wants and needs. Taking in consideration what you want. Advertising is selling a product. Advertising just appeals to your ID. Their goal is to sell as many of that product as possible! Here are some definitions of both.
