Advertising
 A certain amount of advertising is of an informative kind, the aim simply being to let consumers know what goods and services are available—“consumer education” as it is sometimes called. Most advertising, however, is of a persuasive or competitive kind, the aim of which is to persuade people to buy one thing rather than something else.
 Advertising is a selling cost particularly associated with imperfect competition. Advertising is a way of marketing goods. In the sale of branded goods, advertising is essential in order to try to impress on consumers that one maker's brand is superior to all others, although in fact the only difference between brands may sometimes be in their trade marks and labels.
 Any producer with some degree of monopoly, however slight, will generally find it more advantageous to advertise his products widely and at considerable expense rather than cut his prices.
