1. Advertising is the largest, fastest and most extensive information dissemination medium.

Through advertising, enterprises or companies can convey information about the characteristics, functions, uses and suppliers of products and services to consumers, communicate with producers and demanders, attract consumers' attention and interest, and promote purchases.

2. Advertising can stimulate and induce consumption. The consumer's demand for a product is often a potential demand, which sometimes contradicts the actual purchase behavior.

The visual and sensory image and inducement caused by advertisements can often arouse consumers' realistic desire to buy. Some new products that are cheap and marketable are difficult to open the market because they are not known to consumers, and once they are advertised, consumers will buy them one after another.

3. Advertising can better introduce product knowledge and guide consumption. Through advertisements, the performance, quality, use, maintenance and installation of products are comprehensively introduced, and their doubts and worries about maintenance, maintenance and installation are eliminated, thus generating a desire to buy.

Advertising can promote the development of new products and technologies. The emergence of new products and technologies is cumbersome and slow to promote by administrative means, which has great limitations. And through advertising, direct meeting with consumers can make new products and technologies quickly gain a foothold in the market and succeed.

Extended data:

The earliest advertisement in the world was carried out by sound, which is called oral advertisement, also known as hawking advertisement. This is the most primitive and simple form of advertising. As early as the early days of slave society in ancient Greece, people publicized and shouted rhythmic advertisements by selling slaves and livestock.

The streets of ancient Rome were full of hawkers' cries. Carthage, a highly developed trade zone in the vast Mediterranean region in ancient times, was once famous for its numerous hawking voices all over the city.

Trademark font size is also one of the ancient forms of advertising. The name of the store originated from Pompeii. In the Roman Empire, people used font-sized signs to promote gladiators and circus performances. The brand name is symbolic, such as a dairy factory in ancient Rome marked with goats; A mule pulling a millstone represents a bakery; The whipped child is a symbol adopted by the school.
