Our world has faced some remarkable changes over the past few decades due to the rapid development of new technology and the Internet. However, a few years back, a new era began, an era where ordinary people have a 'say' on every possible matter, anytime, anywhere - the emergence of social media has altered our lives enormously by giving everyone the opportunity to be a publisher and a communicator. This, in turn, has had a huge impact on the Public Relations practice, which has always been concerned with communicating and building relationships with various publics on behalf of organisations. This book describes how exactly social media altered the PR industry and the way practitioners are doing PR using social media in their professional and private lives. It is therefore especially useful to both students and professionals in the fields of PR, Social Media, Communications and Marketing, or anyone else who is interested in learning more about social media's impact on PR.
