Advertising is typically designed to make consumers more aware of people, places or products. In some cases the advertising occurs as a public service, such as a campaign to make people more aware of the dangers of smoking or alcohol use. In other instances, the purpose of advertising is to gain the interest and trust of consumers.
Advertisers seek to increase interest in buying a product, visiting a place, or using a specific service. Commercial advertising in general is the use of advertising to generate revenue.
