What is PR?

This is a question Public Relations professionals and students alike ask themselves quite often. There are many definitions of PR. Last semester my PR Theory class had a ongoing discussion of this very question all semester. We came up with answers like "managing strategic relationships", "managing and maintaining reputations and relationships with the media and various publics", "relationship builder", "creating, maintaining and managing relationships that benefit each party" etc. 
Yesterday, PRowl Public Relations posted on their blog a graphic that PRNewswire compiled of all the definitions of PR that their followers and friends came up with: http://www.bloglovin.com/frame?blog=2355207&link=aHR0cDovL3Byb3dscHVibGljcmVsYXRpb25zLmJsb2dzcG90LmNvbS8

PR(Plus) made a very creative video with how they define public relations.
