The intersection of frustrated audiences with unaware presenters can often create dramatic and public breakdowns of communication and even mob mentality. In this book, master presenter and communications expert Cliff Atkinson shows that if presenters embrace the changes and join the new conversations with audiences, are harnessed and the conversation with audiences properly handled, the outcome can be a new, more effective form of communication. At the South by Southwest Interactive Festival in 2008, audience members using Twitter confronted a presenter during her interview with Facebook CEO Mark Zuckerberg when they thought she was straying off track. At SXSW 2009, author Guy Kawasaki called out to the audience, Who is Mary Ann? and when she raised her hand, he directly asked her confronted an audience member in front of hundreds of people, asking her why she was calling him a vulgar name on Twitter! Far from being isolated incidents, these examples are signs of the future of live presentations, when audience members shift from passive recipients to active participants, and even presenters become more assertive in engaging the audience. The Backchannel describes the massive impact of social technology on the live presentation environment, and lays out practical steps that audiences and presenters can take to do to take advantage of the situation harness the change to get better results for everyone involved.
