Advertising and publicity are two important promotional tools used in marketing to create awareness about a product, service, brand, organization, or idea. Both help businesses communicate with customers and influence their perceptions and buying behaviour. However, they differ significantly in terms of cost, control, credibility, message delivery, and the nature of communication.

Large television campaigns, outdoor campaigns and digital advertising campaigns can require considerable financial resources. Advertising is therefore particularly expensive when a company wants frequent and extensive exposure.
