I would define public relations as the maintenance of a favorable image kept up by another company or person. An example of public relations would be references used on a job application. The references will most likely give positive reviews of the applicant, and give the employers reasons to hire the applicant. They will most likely only speak about events that benefit the applicant. I also think that lawyers could fall into public relations. Lawyers will try and prove that their client is innocent of the charges being pressed, or try and lessen the verdict of the judge. The first example is public relations on an unknown person, while the second example is public relations on a person with a negative background to start.
