PR has evolved from PR 1.0 (traditional PR using tools like press releases) to PR 2.0 which utilizes online and social media. PR 2.0 requires more interaction, user-generated content, and real-time engagement as control is lost and gatekeepers like journalists have less influence. Good content is now needed to engage fragmented audiences across many online channels. Issues like astroturfing and fake identities online require transparency and responsiveness from PR professionals. The future of PR will be social, real-time, focused on quality content, and utilize multiple channels and tactics.
