This final thesis deals with public relations in the company Philips. Nowadays, the business activities of any company cannot be successful without an efficient promotion. Every company must identify which methods and channels of communication they can use to send information about their products and services or their activities to their consumers and a broader public. In order for the promotion of a product or a service to be successful, it is necessary to pay special attention to all aspects of the promotion mix. Nowadays, public relations are an essential promotional activity used by both micro and macro businesses, including the company Philips, which produces cardiology equipment, lighting solutions and skin care products for men and women. Out of the elements of the promotion mix, Philips most commonly uses public relations to establish the best contact possible with their target audience. The main role belongs to their official internet page, as well as social networks like Facebook and Instagram. The purpose of this paper is to show how marketing decisions affect the behaviour of the consumers, how public relations create an image about a product or a service and how Philips conducts business and promotes its products through standard media of communication and through a series of promotional resources. The content of this paper leads to the conclusion that public relations have an increasing role in creating a positive and firm market position.
