Public relations is a management tool used by leaders to establish beneficial relationships with other leaders and groups. PR people identify key constituencies, evaluate relationships, and design policies to improve relationships and build a positive image. While PR uses mass media to transmit messages, its goal is not media itself. PR can influence news coverage through press releases, conferences, and junkets which provide free travel, hotels, and access to celebrities in exchange for media coverage. Successful PR strategies include appearing open, making leaders available to journalists, and spinning negative news positively.
