Public relations involves using mass media outlets like news stories to create a positive image for a company, product, or service rather than direct sales promotion. The objective is to present a favorable impression to customers, employees, and the public through activities like assisting with new product launches, countering negative publicity, and influencing target groups. Public relations encompasses functions such as media relations, publicity, community involvement, and promoting goodwill through various types of campaigns, publications, events, and sponsorships.
