Social media has changed the role of public relations in several key ways:
1) Consumers now perceive social media as a more trustworthy source of information than corporate communications, giving them more power in the marketplace.
2) PR professionals have lost some control over messaging as consumers can now talk directly with each other and spread information to vast audiences through social platforms.
3) New PR strategies focus on engaging consumers through social media by encouraging feedback, sharing consumer stories, and participating in online discussions while providing full disclosure of the organization represented.
